But not very far. Although I checked the pinout several times, I can't get the simplest of programs to set a digital pin high (the serial monitor works). Here's the killer code:

  •         RECYCLINATOR III

  •            R/C Control

  •        26 September 2021

const byte RC_Control_pin = 23;
const byte Mtr_Enable_pin = 24;
const byte RC_Active_pin = 25;

void setup() {
Serial.begin(9600);
pinMode(RC_Control_pin, OUTPUT);
pinMode(Mtr_Enable_pin, OUTPUT);
pinMode(RC_Active_pin, OUTPUT);
digitalWrite(Mtr_Enable_pin, HIGH);
}

void loop() {

}

I've looked at every pin and besides the power pin, the only pins high are reset.

The pin assignments I'm using are:
D5 23 RC_Control_pin
D6 24 Mtr_Enable_pin
D7 25 RC_Active_pin
