This is based on the works of kelvineyeone and his project at https://www.hackster.io/kelvineyeone/read-pwm-decode-rc-receiver-input-and-apply-fail-safe-6b90eb
This is arudino based code for the pro micro to control gear, differentials and light with two channels
Channel 1 is designed for a toggle switch on your remote, it activates on high PWM.
- short press: toggle low and high gear
- long press: toggle light
- double press: reset state (blick lights)
Channel 2 is designed for a 3 way switch, each direction toggles the respetive differential.
On power up as well as on reset the lights blink, to confirm the controller is operational as well as visual feedback.
Designed and tested with a pro micro 5v/16MHz. This is important as the interrupr hooks are mapped to the board but might work on others.
Open the arduino IDE change parameters as needed and upload to chip.
All wiring is configured in the trx4-mixer.ino as macros at the top of the file.
- PIN 8: PWM signal from receiver to control gearing and light
- PIN 9: PWM signal from receiver to control front and back differentials
- PIN 10: PWM signal from receiver to control winch. THIS needs extra hardware and is only a proof of concept
- PIN 3: control the gearing servo
- PIN 5: control front differential servo
- PIN 6: control back differential servo
- PIN 16: control lights
Note: light pin is simply set to HIGH as it is assumming you are running a Traxxas TRX8028
- PIN RAW: any positive from the receiver
- PIN GND: any negaive from the receiver
