LIGHT SENSOR micro:bit It is possible to use an LDR (Light Dependent Resistor) as an analogue input. Using the code shown the LED matrix will change from 0 displayed if it is light to X as soon as it goes dark. The resister combined with the LDR creates a potential divider, this creates the trigger to change the metric display. You can change the analogue value from 0 to 1045. for the LDR. Try experimenting with the values to see what happens with higher and lower values. How would you change the code to make the LED switch on if it is light and off if it is dark?
