#include <IRremote.h> const int IR_LED = 9; IRsend irsend; void setup() { Serial.begin(9600); irsend.enableIRIn(); } void loop() { if (Serial.available() > 0) { String command = Serial.readStringUntil(' '); if (command == "on") { irsend.sendNEC(0xFFA25D, 32); } else if (command == "off") { irsend.sendNEC(0xFF629D, 32); } } } This code uses the IRremote library to generate NEC IR signals. You can modify the code to support different IR protocols and devices.
A USB-C IR blaster is a device that connects to your computer or smartphone via USB-C and transmits IR signals to control devices such as TVs, air conditioners, and other appliances. It’s a simple yet powerful tool that can simplify your smart home experience. usb-c ir blaster diy
