Introduction: Connect HM-10 to Micro:bit Using Bluetooth
It all started when I was asked to make a automatic irrigation system. For notifying the user the microbit had to be connected to the HM-10. There was no other tutorial about how to do it, so I studied the Bluetooth connectivity and made an example in which the microbit shows a happy face when it is connected to the HM-10 and shows a sad face when it is disconnected.
NOTE : THIS PROJECT DOES NOT INCLUDE SENDING AND RECEIVING MESSAGES THIS WILL BE DONE IN A FUTURE PROJECT.
1: HM-10 Bluetooth Module (Please keep in mind that other modules have not been tested)
2: Arduino UNO
Step 1: Connect the Arduino to HM-10
1. Connect 3.3V of Arduino to the VCC of HM-10.
2. Connect GND of Arduino to the GND of HM-10.
3. Connect D0 of Arduino to RX of HM-10.
4. Connect D1 of Arduino to TX of HM-10.
Step 2: Upload a Blank Sketch to Arduino
Just open Arduino IDE and upload the default sketch that opens.
Step 3: Setup HM-10
Step 4: Program the Micro:bit
Step 5: Connect Micro:bit to With HM-10
