==Introduction==
The keyestudio Bluetooth 4.0 shield is an integration of sensor shield and HM-10 Bluetooth-4.0, fully compatible with UNO R3. So it is very easy to stack it onto the UNO R3 board.
The shield has extended all the digital and analog pins out into 3PIN, simple to connect the sensor using 3PIN wire.
It also come with a HM-10 Bluetooth-4.0 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 connect two jumpers, need to set the virtual serial port for UNO R3 board, that is D2 to TX, D3 to RX.

Keyestudio Bluetooth 4.0 shield integrates sensor expansion board with HM -10 Bluetooth 4.0. It is fully compatible with keyestudio UNO R3 control board, which can work only through stacking the expansion board on the keyestudio UNO R3 control board, easy and convenient. It extends all digital ports and analog ports of keyestudio UNO R3 control board in the form of steering gear sequence. A sensor only needs a universal 3P sensor cable, which is very simple and fast. <br>
==PINOUT Guide==
Expansion board with HM -10 Bluetooth 4.0 can be used for the bluetooth communication, and toggle switch control the power supply for Bluetooth. There is a jumper cap set on the board, and the default jumper wire achieves the direct communications between bluetooth module and keyestudio UNO R3 control board serial port. If the jumper cap connects another two jumper wires, achieving a serial port communication needs the keyestudio UNO R3 control board to set up the virtual serial port, which needs that the digital port 2 is set to RX, and digital port 3 is set to the TX.

Keyestudio UNO R3 Board

Introduction

The keyestudio Bluetooth 4.0 shield is an integration of sensor shield and HM-10 Bluetooth-4.0, fully compatible with UNO R3. So it is very easy to stack it onto the UNO R3 board. The shield has extended all the digital and analog pins out into 3PIN, simple to connect the sensor using 3PIN wire. It also come with a HM-10 Bluetooth-4.0 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 connect two jumpers, need to set the virtual serial port for UNO R3 board, that is D2 to TX, D3 to RX.

Test Code

int val; 
int ledpin=13; 
void setup() 
{ 
Serial.begin(9600);
 pinMode(ledpin,OUTPUT); 
} void loop()
{ val=Serial.read(); 
if(val=='a')
 { 
digitalWrite(ledpin,HIGH); 
delay(250); 
digitalWrite(ledpin,LOW); 
delay(250);
 Serial.println("keyestudio");
}
}


Example Use

Stack the shield onto keyestudio UNO R3 board, power up and upload the code. Turn on the slide switch to power the HM-10 Bluetooth-4.0.
