DIY RC Transmitter & Receiver: Arduino Code + Circuit Diagrams

Building a drone? Start with this DIY RC Transmitter & Receiver! In the video I show how to make a 6-channel custom RC transmitter and receiver using Arduino & NRF24L01. This budget-friendly setup is perfect for controlling drones, robots and RC cars, and it’s comparable to commercial transmitters like FlySky.

What you get

• Arduino code for the transmitter and the receiver (ready to upload)
• Transmitter circuit diagram: full wiring of the handheld remote
• Receiver circuit diagram: wiring for the receiver that goes in your drone / RC car

Main parts used

Transmitter: Arduino Nano, NRF24L01 + PA/LNA (with antenna), 2 joysticks, 2 toggle switches, 128×64 I2C OLED display, push buttons for fine-tune trims, buzzer, 3 × 18650 cells with a 3S BMS, buck converters for charging (12.6 V) and for the radio (3.3 V).

Receiver: Arduino Nano, NRF24L01, AMS1117 3.3 V regulator with a 10 µF capacitor, 3-pin headers for each channel. Powered by 5 V from your ESC or another device.

Watch the full build video above, then download the files and start building. Pay what you want: free is fine, and anything extra helps me make more projects.
