Final answer:
To make a photocell resistor code on a Microbit, you need to connect a photocell to an analog pin on the Microbit and use the Microbit's programming environment to read the resistance value and perform actions based on the light level.
Step-by-step explanation:
To make a photocell resistor code on a Microbit, you first need to connect a photocell to one of the analog pins on the Microbit.
A photocell is a light-sensitive resistor that changes its resistance based on the amount of light it receives.
The Microbit can read the resistance value using the analog input pins.
Once the photocell is connected, you can use the Microbit's programming environment to read the resistance value and perform various actions based on the light level.
Here is an example code snippet that reads the resistance value of the photocell:
from microbit import *
while True:
light_level = pin0.read_analog()
display.scroll(light_level)
This code continuously reads the analog value from pin 0 (where the photocell is connected) and displays the value on the Microbit's LED screen. You can modify the code to perform different actions based on the value of light_level.
