The A, B,Īnd C buttons select a channel (red, green, or blue). The IR Remote's power button turns the LED on or off. RGB Remote Control uses a combination of SparkFun's This sketch uses Ken Shirriff's *awesome* IRremote library: Then upload it to your Arduino to create your very own, remote controlled, RGB LED. RGB Remote ControlĬopy and paste the below code into your Arduino IDE. We don't have a use for the IR LED yet, so, for now, set that safely aside. If you swap pins, make sure you reflect those changes in code! The output of the IR receiver connects to D11, but it could be connected to any digital input pin. Now that we can read the button presses, we can control your project with IR! Simply comment/uncomment the code for the remote or update the values for the remote that you are using. If you have an older version of the IR remote control or received one outside of our catalog, make sure to update the code to reflect the corresponding button presses. Press the buttons on the IR remote to see the associated button values. Serial.println("IR RECV Code Value Not Defined or Button was Held Down") ![]() Irrecv.enableIRIn() // Start the receiver Note: Comment out this section if you are using this w/ the older remote. Note: Uncomment out this section if you are using this w/ the older remote. If you want to lookĪt the individual timing of the bits, use this code: Note: This code also works with cheap remotes. Note: This is based on Ken Shirriff's code found on GitHub. If using with the IR Receiver Diode (SEN-10266): If using with the IR Receiver Breakout (SEN-8554): Hex value when a signal is received by an IR receiver. language:cĭescription: By pressing on one of the SparkFun infrared remoteĬontrol's buttons, the serial monitor will output the associated Then upload it to your Arduino to view the values associated with each button. The Arduino has an on-board surface mount LED that’s hard wired to digital pin 13.Copy and paste the below code into your Arduino IDE. ![]() You can make the LED flash by changing the length of the HIGH and LOW states. To turn off the LED, it needs to send a LOW signal to the pin. To turn on an LED, the Arduino needs to send a HIGH signal to one of it’s pins. It includes all of the parts, wiring diagrams, code, and step-by-step instructions for 58 different robotics and internet of things projects that are super fun to build! Controlling the Arduino’s LED ![]() The 3-in-1 Smart Car and IOT Learning Kit from SunFounder has everything you need to learn how to master the Arduino.
