Keyestudio Bluetooth 4.0 Shield Expansion Shield Board for Arduino UNO R3

The Keyestudio Bluetooth 4.0 shield is the integration of a sensor shield and a HM-10 Bluetooth-4.0, to be fully compatible with UNO R3. It's very easy to stack onto the UNO R3 board. The shield has extended all the digital and analog pins out to 3PIN headers, so it's simple to connect sensors using 3PIN wire. The HM-10 Bluetooth-4.0 is used for Bluetooth communication. The slide switch is used to control the power supply for Bluetooth. Onboard is set with jumper cap, default by communicating the Bluetooth module to UNO R3 serial port. If you connect two jumpers, you'll need to set the virtual serial port for UNO R3 board, that is D2 to TX, D3 to RX.

Sample Code

Results

The keyestudio Bluetooth 4.0 expansion board is stacked on the keyestudio UNO R3 control board. After the power is turned on, burn the procedure and dial the toggle switch to power on HM-10 Bluetooth - 4.0.

Open APP HC-COM, click search device, select the device, device is connected; the LED on the Bluetooth module is on. Enter "a" in HC-COM, click send, Bluetooth APP will display keyestudio. Every time HC-COM sends an "a", the Pin13 LED on the main board blinks once.
