This project consists in the development of an app with Android Studio (Kotlin) to communicate with Arduino Nano to control a module of 16 relays and a temperature sensor.
It can be used to automate home devices and other projects.
Components:
ArduinoNano.
Bluetooth module HC-05.
DS18B20 Temperature Sensor Module.
16 channel relay shield (Hacked to operate- with 5 Volts).
Arduino NANO I/O Extension Shield.
12 Volts power adapter.
