On your servo motor MG996R, you have tree wires:

• (Yellow) PWM signal from EPS32
• (Red) 5V
• (Brown) GND

Do you supply the servo with 5V?

You can consider GP26_A0 as an high impedance, so current iGP26_A0 can be considered as 0A.
Current iR1 = iR2. As R1 depend on light, i = 3.3V / (R1 + R2), so i is not constant.

Example with different value for R2

For a servo motor duty time on need to be between 1ms and 2ms. Currently the duty cycle has to be in the range of 0-1023.
So on an ESP32, duty cycle for 1ms is around 51 and 2ms is around 102.

An other approach, would consist of using an LED as a light sensor, amplified by a transistor.

Based on proposed schematic, you can read photocells with this code. from machine import Pin, ADC # Set sensors sensor_a = ADC(Pin(26)) # ADC0 sensor_b = ADC(Pin(27)) # ADC1 sensor_c = ADC(Pin(28)) # ADC2 # Read sensors # read value, 0-65535 across voltage range 0.0v - 3.3v sensor_a.read_u16() senso...

Are you looking for something like that?

As Peter says, it's what I'm implementing for project MicroPython-MQTTremote not finished yet.
config.json
And the code that implement the config.json is here.

Can you look at what I did for my logger? It's here.

Instead of having a config.py, you should have a config.json file.

The CS-D808 datasheet says page 6, min operating voltage 30V, typical 48V to 60V, max 80V.
The enable pin should be high to work, page 8.
