Controlled by a smartphone app, a cheap Arduino board with an HC-05 Bluetooth module ran the show. However, when this was all assembled, the car was too heavy to climb walls or stick to the ceiling.

An HC-05 Bluetooth module is connected to an Attiny85, with some transistors to control a 5V power output. The Arduino takes care of a bluetooth connection and uses a serial input to control the ...

Description This project demonstrates a biofeedback system using Arduino UNO. It reads Galvanic Skin Response (GSR) data via the CJMCU-6701 sensor and streams this data to a Bluetooth terminal app on ...

The wearable smart glasses are controlled by an Arduino Nano Every microcontroller combined with an HC-05 Bluetooth module, that enable the glasses to connect to the mobile app, while a small LiPo ...
