// IR control a Nakamichi tapedeck with Arduino, TSOP4838 and Sony CamCorder remote
// URL: https://github.com/Arduino-IRremote/Arduino-IRremote/wiki/Receiving-with-the-IRremote-library
// - drive LED's, later drive FET/transistors
// - test boards: Uno(ok), Nano(??), ESPxx(??)
// - use expander (i2c mcp23008...)
// - add MQTT status/control?
