K1063 Light Controlled Motor

K1063 Light Controlled Motor Kit – Sensor Motor Speed Control Project (Assembly Required)

The K1063 Light Controlled Motor Kit is an engaging project that uses a light dependent resistor (LDR) to control the speed of a DC motor according to surrounding light levels. Two transistors configured as a Darlington pair provide increased current gain, allowing the circuit to drive motors up to 1 amp. As light levels change, motor speed responds accordingly, while a high-brightness LED gives visual feedback by changing brightness with motor speed. With adjustable sensitivity via an onboard trimpot, this kit gives students a practical introduction to sensors, transistor amplification, and motor control systems. It can also be expanded into creative projects such as vibrabots, alarms, or forward/reverse systems using an optional DPDT switch.
