Step 1: List of Components
In this tutorial, (please refer the image above) the components needed are as follow:
- Battery 2-3 cell LiPo
- Arduino UNO
- Brushless DC Motor
- Male to Male Jumper cable
- HW30A Brushless Motor Speed Controller
- USB 2.0 cable type A/B
- Variable Resistor 10k ohm
- Crocodile Clip
Step 2: Hardware Installation
Refer the diagram above for your reference.
- Connect the battery 2-3 LiPo to HW30A Motor Speed Controller (ESC).
- Refer the diagram, connect together the HW30A Motor Speed Controller (ESC) with Arduino UNO
- Last HW30A pin output connect to Brushless DC motor
Step 3: Source Code
Download this sample source code and open it in your Arduino IDE
Step 4: Uploading
After open the code in Arduino IDE, go to the [Tools] --> [Boards Manager] --> select [Arduino/Genuino UNO] as we using Arduino UNO in this tutorial.
Then connecting the Arduino UNO to PC, after that select the correct port (go to [Tools] --> [Port] --> Select correct port for Arduino UNO).
Next, compile and upload the code into your Arduino UNO.
