This is another example project of the Abetoo IoT Framework. In this case an application for remote control of an arduino-based circuit from an android app. The arduino board used is based on the popular module esp8266. The main goal of the application is to control a Peltier element, a Fan and to show messages sent from the android app. A board with relays is used to activate/deactivate both the Peltier element and the fan. A LCD is used to show the messages received.
PinOut of the NodeMCU V3 board (esp8266 + usb-232),
In the schematic is also used a Relays PCB and a LCD,
