/* Copyright 2017 stufisher * An IR LED circuit *MUST* be connected to ESP8266 GPIO4. * * TL;DR: The IR LED needs to be driven by a transistor for a good result. * * Suggested circuit: * https://github.com/markszabo/IRremoteESP8266/wiki#ir-sending * * Common mistakes & tips: * * Don't just connect the IR LED directly to the pin, it won't * have enough current to drive the IR LED effectively. * * Make sure you have the IR LED polarity correct. * See: https://learn.sparkfun.com/tutorials/polarity/diode-and-led-polarity * * Typical digital camera/phones can be used to see if the IR LED is flashed. * Replace the IR LED with a normal LED if you don't have a digital camera * when debugging. * * Avoid using the following pins unless you really know what you are doing: * * Pin 0/D3: Can interfere with the boot/program mode & support circuits. * * Pin 1/TX/TXD0: Any serial transmissions from the ESP8266 will interfere. * * Pin 3/RX/RXD0: Any serial transmissions to the ESP8266 will interfere. * * ESP-01 modules are tricky. We suggest you use a module with more GPIOs * for your first time. e.g. ESP-12 etc. */ #ifndef UNIT_TEST #include #endif #include #include #include IRTrotecESP trotecir(4); // An IR LED is controlled by GPIO4, NodeMCU D2 void setup() { trotecir.begin(); Serial.begin(115200); } void loop() { Serial.println("Sending..."); // Set up what we want to send.
