I am using Arduino to control an SM5100B GSM device, everything works except when I want to send an SMS after receiving another. I get this, Error code: O K > + C M G S : 2 5 ...
I would like some sort of method to create a fairly long sequence of random numbers that I can flip through backwards and forwards. Like a machine with "next" and "previous" buttons, that will give yo...
I made a program that sends out data to my arduino which detects what was sent and then turns on the correct pin according to what key is pressed. When using the arduino software from my windows comp...
I'm using two Arduinos to sent plain text strings to each other using newsoftserial and an RF transceiver. Each string is perhaps 20-30 characters in length. How do I convert Serial.read() into a str...
I am making a vector of "waypoints" on the Arduino. Each waypoint is an object. The Arduino will obviously need to store multiple waypoints for waypoint navigation. But instead of storing these waypoi...
I've got a SWIFT application that have to send a value to my Arduino with Bluetooth LowEnergy module! I've done correctly the search and connection parts but I'm not able to send and receive any data...
Currently the python program must know which port a device (Arduino) is on before Python can communicate the device. Problem: Whenever the device is plugged out and back in, its COM port changes, so ...
I have an Arduino connected to my computer running a loop, sending a value over the serial port back to the computer every 100 ms. I want to make a Python script that will read from the serial...
Math was never my strong suit in school :( int input_start = 0; // The lowest number of the range input. int input_end = 254; // The lowest number of the range input. int output_start = 500; // The l...
I have this arduino sketch, char temperature; float temp = 10.55; sprintf(temperature,"%f F", temp); Serial.println(temperature); temperature prints out as ? F Any thoughts on how to format ...
