/* * IRremoteESP8266: IRServer - demonstrates sending IR codes controlled from a webserver * Version 0.3 May, 2019 * Version 0.2 June, 2017 * Copyright 2015 Mark Szabo * Copyright 2019 David Conran * * An IR LED circuit *MUST* be connected to the ESP on a pin * as specified by kIrLed below. * * TL;DR: The IR LED needs to be driven by a transistor for a good result. * * Suggested circuit: * https://github.com/crankyoldgit/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. */ #include #if defined(ESP8266) #include #include #include #endif // ESP8266 #if defined(ESP32) #include #include #include #endif // ESP32 #include #include #include const char* kSsid = "....."; const char* kPassword = "....."; MDNSResponder mdns; #if defined(ESP8266) ESP8266WebServer server(80); #undef HOSTNAME #define HOSTNAME "esp8266" #endif // ESP8266 #if defined(ESP32) WebServer server(80); #undef HOSTNAME #define HOSTNAME "esp32" #endif // ESP32 const uint16_t kIrLed = 4; // ESP GPIO pin to use.
