This DIY radio controller resembles one you’d find on the market
If you’ve ever considered constructing your own wireless RC transmitter, be sure to check out this build by Electronoobs.
The device uses an nRF24L01+ module to transmit inputs from a pair of joysticks and toggle switches, along with an Arduino Nano for interface and control.
What sets this project apart from his previous versions, however, is the very nice 3D-printed enclosure for the electronics and a pair of high-quality joysticks that allow for precise input.
Additionally, Electronoobs’ latest design features tuning buttons to properly center the sticks, and an OLED display to show the actual input value that it’s sending to the receiver (a simple Nano/nRF24 setup for demo purposes).
Yes, I’ve made another radio controller. Why? well, I wanted to have a more commercial look. So, I’ve designed a 3D case, then I’ve used some high quality joysticks in order to have better analog read, It has an OLED screen so we could see the data we send and we could also digitally adjust the data. It also has 2 modes, linear and exponential
