Hands on Night light implementation by using transistors (npn & pnp) and photoresistors, programming and Robotics. Explanation of Collector, base and emitter of transistor circuit, then simulation tool (tinkercad) is used to iterate on circuit. Tool would be demostrated to students so they understand its functioning. Discuss each part role and its feature.

Testing would be carried out to assemble a part for night light getting on when it is dark. The required material for playdough circuit would be provided.
