The receiver is one of the most important components in any remote control toy. It receives the signal from the transmitter and sends it to the motors or actuators that control the toy. If you are building a micro-sized remote control toy, you need a receiver that is small, lightweight, and has a long range. One option is to build your own receiver using an Arduino board and a Bluetooth module.
t is basically an Arduino board with a built-in BLE module. This board is powerful enough to run any common Arduino version, such as the Arduino Nano, Mini, or Uno. I love working with the Arduino Nano, so I burned an Arduino Nano bootloader to this board. Here are the specifications:
- Size: 18.74 mm* 13.02 mm
- Power: 3.3V to 5V
- MCU: ATMega328p
- OS: Arduino Nano
- Clock: 16Mhz Crystal
- Bluetooth version: BLE 4.0
- Baudrate: 115200
- Built-in LED on D2
- Power LED
- Anti-Reverse polarity
This board needs a piece of code to work, which we can call firmware. The firmware was already burned into the board when you received it. The last thing you need is an application on your phone to connect with this board. We only have the app for Android, and you can download it from here.
The video about the board can be accessed here.
