Follow the next tutorial: Install the ESP8266 Board in Arduino IDE; Code Aug 11, 2019 · If you want to connect one or multiple switches to your Arduino, ESP8266 or ESP32 microcontroller you have to use a digital I/O pin to read the current state of the switch or button. The diagram shows wiring for a 2-channel relay module, wiring a different number of channels is similar. Now the best part is the community has made programming this inbuilt micro-controller extremely easy by adding Arduino support. SCL is the I2C clock pin. The default SPI GPIO pins of ESP8266 are being used to connect with each of the remaining I2C terminals of the BMP180 module. If you were to expand the code in the ESP8266 to do more, different things how would you go about it. When a command is entered into the serial monitor on the computer the Arduino will relay it to the ESP8266. cxtzaoihhbjlavtzhnqvyfsgtzxohximjbujyxihgtnkmzhkoftjvd
