This Solderless kit is uses a photo-transistor to sense the ambient light level. When the light falls below the desired level, the kit will turn ON two bright LEDs which can be used as a “Night Light”.
The circuit will also turn OFF when the ambient light level increases back above the threshold level.
The level at which the Kit responds can be adjusted by the on-board Trimmer Potentiometer.
No Soldering is required as the kit comes with sockets already installed and just needs the correct components to be inserted.
The kit lends itself to simple experimentation.
Construction Notes come with each kit. The Notes include step-by-step graphics of the assembly process.
The student notes are aimed at allowing students to work at their own pace, and achieve a high probability of success.
