Building the Internet of Things with the ESP8266 Wi-Fi Module and ThingSpeak

The ESP8266 Wi-Fi Module is a low-cost Wi-Fi radio with a microcontroller on board. Costing less than $5 US, the ESP8266 brings connectivity and programmability to any “connected project” such as temperature sensor monitoring or aquarium control.

The ESP32 module is an MCU with integrated Wi-Fi and Bluetooth connectivity for many IoT applications. I recommend the HiLetgo ESP32 module to get started with the ESP32. This will allow you to use the Arduino IDE to program the module over USB and leverage your existing experience as you learn.
