PCB dimensions: 53mm x 41mm.
Requires 3 x AA batteries.
An electronics project with real life application. Students complete the circuitry following the instructions and then the real design begins. What will the night light look like? This design challenge allows a range of possible fabrication processes. If your school has laser cutting, vacuum forming or CNC capability then put them to good use.
The colour changing LED on this kit turns on when it goes dark and stays on for a period of time.This makes a good night light and because the LED is only on for a small amount of time the batteries last much longer. There is an on board trimmer to set the light level at which the LED turns on and another trimmer to set how long the LED stays on for.
The maximum duration is about 30 minutes. When set to 15 minutes and activated once a night the batteries will last two months.
