The servo library also uses hardware interrupts using TIMER1. IRLib uses your board’s built in hardware timers to generate an interrupt every 50µs so it can poll the input pin to see if it has changed. The example as presented here should work okay on OSOYOO Basic board or Mega however if you are using Arduino Leonardo, Arduino Micro, Arduino Yun or other ATmega32u4 based systems, you will have to make a slight modification to IRLib. Special Instructions for ATmega32u4 based systems #include //must copy IRremote library to libraries #include #define plus 0xFF18E7 //clockwise rotation button #define minus 0xFF4AB5 //counter clockwise rotation button int RECV_PIN = 3 //IR receiver pin Servo servo int val //rotation angle bool cwRotation, ccwRotation //the states of rotation IRrecv irrecv ( RECV_PIN ) decode_results results void setup ( ) Then load up the following sketch onto your board. The green power LED (labelled PWR) should go on.Open the IDE and choose corresponding board type and port type for you project. Then detect the HEX code of the buttons used to control the servo motor assume you will use two buttons of your choice, one for clockwise rotation and another for counter clockwise rotation.įor example, use (▲) for clockwise and (▼ for counterclockwise, so you have to get their HEX codes.Īfter above operations are completed, connect the board to your computer using the USB cable. Then open the serial monitor and try to click on any button on the remote control to send a signal to the IR receiver the HEX code of each button must appear in the serial monitor as shown in the picture. Open IRremote demo example from IDE, then upload it to the board. Use the IRremote Library to Control a Servoįirst, download the IR remote library for Arduino from here: IR library Follow the steps for wiring in the pictures. The wiring for the IR receiver and servo motor are shown in pictures. We use the IR receiver to read IR signals from the remote control. ![]() ![]() ![]() We use OSOYOO Basic Board to control the servo motor and give us the functionality we want. Osoyoo Basic Board (Fully compatible with Arduino UNO rev.3) x 1.You should know that the remote control sends Infrared (IR) signals, so we will learn how to receive and read these signals using board compatible with Arduino. This will give you a general concept on how to control remotely. In this lesson, we will learn how to control a servo motor with a remote control. Note: ALL OSOYOO Products for Arduino are Third Party Board which is fully compatitable with Arduino Overview
