SensoDuino: Configure and Transmit Sensor Data to Arduino Over Bluetooth

This video guide demonstrates how to pair and connect SensoDuino to an Arduino Uno or clone over Bluetooth using the HC-05 module or comparable Bluetooth module. It also explains the formats of the SensoDuino data being transmitted.

Configuring The HC-05 Bluetooth Module with AT Commands

In this video, I will demo how to change the settings of the ubiquitous HC-05 Bluetooth module using the AT command set. The HC-05 comes with a rich set of AT commands to perform various tasks such as changing the module’s default settings including changing the pass code, the device name, and the baud rate. Please refer to the detailed guide on to wire and set-up the HC-05 to the Arduino for AT command mode.
