8. Several Jumper Wires
Wiring Diagram
Desired Outcome
A photoresistor can detect the presence of light in its path. Use a torch light (torch on your smartphone) and direct it on to the surface of the photoresistor. You will notice that the value on the display, which is a measure of intensity of light, increases with increased intensity of light and decreases with decreased intensity of light.
