Expand Your ESP8266 Analog Inputs With $10
ESP8266 is a very powerful module for building an IoT or WiFi-based project. But since it has only one analog input, you may need to use another microcontroller or circuit to connect multiple sensors and data sources with your ESP8266. Allaboutee created the second version of their...
