OK, which components did you plug in e.g. for 2 – Using a Light Sensor & Analog Inputs, they start with a resistor, the phototransistor and 3 wires
(I am looking at their video on youtube)
Have you got the components plugged in to the breadboard exactly as they show?
The next step would then be to run their example code

Code:
import machinelightSensor = machine.ADC(26)etc.Statistics: Posted by neilgl — Sun Feb 22, 2026 10:36 pm
