Timed Night Light Project Kit - Kitronik 2139

A set developed by specialists from Kitronik , designed to build a bedside lamp with a twilight sensor . The kit also includes a potentiometer with which you can adjust the sensitivity of the photoresistor and the LED lighting time. The kit requires soldering of through-hole elements on the PCB .

The elements combined create an unusual night lamp with a twilight sensor.

• Designed for self-assembly, requires soldering of elements
• Equipped with an adjustable light intensity sensor
• Possibility to set the LED lighting time in given lighting conditions
• Powered by three AA batteries - with light for up to 15 minutes and activated once a night, the batteries will last for two months
• The set provides an interesting way to convey basic theoretical and practical knowledge of electronic issues
