For some reason the IR-Diode connected to my Node MCU ESP8266 stopped working.
I changed the IR-Diode because i realised it only requires 1.5V not 3.3V. I added two resistors two split the current but still it´s not working.
I can flash a programm on the Node MCU only if its not pluged into the circuit. I´m really confused can anybody help me?
(I have already tried another Node MCU with the same result)
