Okay so this is part of a small uni module around the arduino board. The task is to simulate traffic lights at a junction. At the moment my code below runs through the sequence with 2 seperate lights. When one set of lights turns RED , the other turns GREEN.In my main loop method I need to add a button for a crossing. I want to be able to check if the button is pressed at each of the delays but do not want to have to hold it down.I have thought about putting it at the top of the loop but then the program will only check if button is pressed in that point therefore the user will have to hold it down?
Code:
int green1 = 13 ;
int amber1 = 12 ;
int red1 = 11 ;
int green2 = 6 ;
int amber2 = 7 ;
int red2 = 8 ;
}
how to pass a string from vb6 into the gsm module ... i am posting vb6 code ... below code passes
check1.caption=11BNELE0455 to MSCOMM2.output...
Static col As Integer
col = 3 lbl: If excelws.Cells(10, col).Value = "" Then excelws.Cells(9, col).Value = Format(Now, "dd/mm/yyyy") If (check1.Value = 1) And (Timer1.Enabled = True) Then excelws.Cells(10, 1).Value = check1.Caption
[Code]...
now i want to access this string a=0455 from c-code of arduino..how can i access this.. below is c-code for arduino uno.what is wrong with it.it is giving me error:invalid conversion from 'int' to 'const char*'.
//decalaration part of my code
#include <SoftwareSerial.h> char inchar[80][5]; // Will hold the incoming character from the GSMshield SoftwareSerial SIM900(7, 8); String textForSMS;
I am trying to implement same thing as given in following images:
i m working on "Wireless surveillance system using zigbee".
But i want to add external PIR motion sensor and wireless zigbee module with Arduino.
The images are stored in SD card. but my goal is when the PIR detects any motion the image should be stored in memory card (Done in attached code)and then that image should be transferred through zigbee (Zigbee Tx is connected with Rx Pin0 and zigbee Rx is connected with Tx Pin1). PIR sensor output is connected with Pin7 of arduino.
So what are the additions/modifications do i require for transmitting image on Pin1 in following code.
I am using this code
Code: // This is a motion-detect camera sketch using the Adafruit VC0706 library. // On start, the Arduino will find the camera and SD card and turn // on motion detection. If motion is detected, the camera will // snap a photo, saving it to the SD card. #include <Adafruit_VC0706.h> #include <SD.h>
I know how to create your basic programm that compiles as a CLI or exports and/or saves data to a .txt file... But how does one build a GUI?
I ask because I am currently working on a programm for my Arduino controlled robot, in which I want to have a virtual on screen controller next to a map of my bots path.
I am working on a project that requires using an arduino microcontroller to control the motion of a servo motor. The arduino language is pretty much C.
The original code is of the form:
Code: #include <Servo.h>
Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
[Code] .....
But the problem is I don't want the motor's motion to behave linearly (constant increments of the pos variable). My desired motion is a sinusoidal like function. How to approach this?
I am quite new to programming, especially with microcontrollers. My guess is that instead of the pos+=1, I would need something like pos+=sin(argument). I am not sure what that argument should be.
I am building a project with an Arduino Uno that involves using analogue IR sensors to detect fast motion. By placing one sensor on top of the other, I want to be able to attain a variable integer from the difference in time between the responses of the sensors.
Here is my code I have so far, it is essentially for detecting motion for 1 sensor and then converting it into a MIDI note depending on how far away the motion is detected. There is also a part which compares the value from the previous time so that only above a certain amount of movement will trigger the note. I also have a variable delay to be controlled by a potentiometer.
Here is the datasheet for the sensors I'm using.
#include <MIDI.h> MIDI_CREATE_DEFAULT_INSTANCE();
int currentvalA = 0; //current sensor A value int previousvalA = 0; //previous sensor A value int valA = 0; // value to store sensor const int valchangeA = 40; //motion change value int del = 0; //variable delay value
I'm writing a version of the classic Snake game. However, my board is not printing correctly. The right hand border is in the incorrect location. Also, when I randomly generate where the food ('X') is located, it only generates on the edges of the boundaries.
#include <iostream> #include <cstdlib> using namespace std; const int ROWS = 21; constint COLS = 61;
I'm programming tic tac toe but the board is not showing numbers, and it is simply stating the winner without any input: (the win conditions are not complete, but it shouldn't matter).
#include <iostream> #include<string> using namespace std; //Write a two-player tic-tac-toe game; use enums when possible to represent the values of the board
I am trying to read from my input file Transactions.data which is set up as follows
V 250190 A 250190 2008 4 8788.00 0.00 000 and so on and so forth.
I am trying to read my V then go to switch (decision) to choose my case and preform further functions. My problem is that i cannot get past the first line so if it was
V 213400 V 123456
My code is supposed to check that the ID (213400) is valid then go on to the next line but it wont do that and prints out the first ID 6 times. My code is as follows:
char descision; ifstream input; input.open("Transaction.data"); if (input.fail()) {cout << "File could not be opened." << endl;} input >> decision;
Im trying to make a Tic Tac Toe board for an assignment. Right now it compiles fine but when I enter an x or o it does not update the board it just prints out the '.'s that the board is initialized to. Also, when I get to player 2 the board will printout twice so its 6 rows or 3 columns. The project uses a main to ask who starts then goes to a play function that asks for inputs and calls the makeMove function to place the x's and o's and the print function to display the updated board.
bool Board::makeMove(int rowIn, int columnIn, char currentPlayer) { if (playBoard[rowIn][columnIn] == '.') { playBoard[rowIn][columnIn] = currentPlayer; return true;
I Cant get my checkers game board to refresh every time i make a move. i have system("cls") But it does nothing of the sort.. To move a pice ive created an illusion which swaps one pieces appearance with another :
I'm trying to read the input without using arrays. I would use fscanf(*arguments*) to get the first char, which is x. Then I call it again to get the second one, which is 1. Now I would need to get the second input, y2. How do I skip the white space character to get to char y ? And is it an effective way to get all inputs though ? (each input, example x1, is read into a function).
I have an HTTP/1.0 webserver that I'm building in C that needs to exhibit CGI script functionality. Specifically, what I'm having trouble with is that I have two processes: process 1 is the webserver, process 2 is the CGI script. I fork in the webserver, and then call exec to run the CGI script (specifically, I used execv()). I've read from the CGI specifications in the RFC that in the case of a webserver receiving a POST request, the CGI script should read the arguments for the POST request from stdin. However, when I write to stdin, it simply echoes what was written to the terminal window and when the CGI script tries to read from stdin, it blocks.
So, with all that said, I'm pretty sure there is some simple conceptual explanation to my problem, but I can't figure it out. Do I need to use pipes or some form of interprocess communication to send the data from the webserver to the CGI script, or can it just be done with stdin (and possible stdout)?
/* This is what I have so far what i am trying to do is to initialize the arrays at zero and output the board to the screen. Part of the problem is the user has the option of the board size.

I'm reading input from a file using an ifstream. The program doesn't seem to read any characters but continually returns eof no matter what file I use. Even when I do ifstream.open(filename) nothing changes. This program is intended to be the lexical analyzer of a compiler, so symbols are returned to indicate what kind of input is in the file.
I'm in a CIS 143 class which is Introduction to Programming using C++. We've been assigned a lab with little to no detail on how to do the things listed.
The purpose of this lab is to practice the file input and output concepts. For this lab you may assume that the input files exist and contain appropriate data inside of them.
Four separate text files* which contain the following lines, different for each file.
(*: This isn't on the lab, but don't worry about what the name, age, id, and major are. those can be random and I can just change them what they need to be)
Name Age Student ID Number Major
Your program should ask the user which of the four input files they would like to open, and then read the contents from the file. Once the contents have been read in, it should output to both the screen and a file named "output.txt" the four values were read in, arranged as follows:
"Hello <name>! You are a <age> years old <major> student, and your ID number is <ID number>"
Now I am by no means saying "Do it for me". I just need to know how to have a user type file1, file2, file3, or file4, and then have the program open that file, then have the output.txt file arrange the wording into the sentence above.
This is what I have so far and I don't think it is anywhere near correct:
#include <iostream> #include <fstream> #include <string> using namespace std; int main() { ifstream inFile; string file1; string file2;
I need to read input from a file , which contains multiple sentences of varying lengths. After each new line char, i need to store that sentence into an array.
I am working on my senior project and my currect task is to make a menu. I dont know what the best way to do it. my code is not complete and i am completely lost. code found below:
The program will prompt the user to enter a every student's first and last name, major ( of 4 choices CMPS MATH PHYSICS or EECE ), and grade. it's agreed that the professor will enter the name NoMore to stop the entry.
the program willl then store the info in a txt file. after closing the input file, the program will open it again read the records one at a time until end of file, and do some statistics including: highest grade, average grade, and highest average by major.
