Hello, I have a problem because I don't know how to program the UNO WiFi board with the built-in esp8266 chip. I don't know how to write a program so that there is a message from the esp8266 that, for example, pin 4 on the Arduino has been enabled. I cannot use the GPIOs as there are not enough...

. If you have actually used all the pins then it remains a transmission by thought. Show the schematic as it is not clear where these GPIOs you have too few, what interfaces you have in use, etc.

Hello, I have a problem because I don't know how to program the UNO WiFi board with the built-in esp8266 chip. I don't know how to write a program so that there is a message from the esp8266 that, for example, pin 4 on the Arduino has been enabled. I cannot use the GPIOs as there are not enough of them. Please help. I should also add that I have already written the esp communication with the internet, now only esp-Arduino is left for me.

Do you have a problem with Arduino? Ask question. Visit our forum Arduino.
