Arduino analog read and light active switch
The repository contains examples of using the MCP23017 expander with Arduino. The MCP23017 expander uses I2C communication with Arduino.
needed equipments: esp8266 or nodemcu sensors(gives analog output) diodes breadboard nstead of having multiple analog pins like other boards, the esp8266 only has one analog pin. We make it possible to read multiple analog values using just one pin. method: By switching sensors on and off, similar to multiplexing, we achieve this. In the first s…
