I build this Solar light using the 12 in 1 Microduino mPuzzle kit. Solar Energy is a type of renewable energy, which means the energy is collected from a source that can be replenished on a human time scale.
Learning Objective: A light sensor is a kind of switch that can help turn things on & off. When there is light, the circuit is on, when there is no light the circuit is off.
Steps to build the Solar controlled Light:
- Place the NPN, two 1-point wire components & one 3-point wire component on the board as shown.
2. Place two 1-point wire components on the top and bottom most part of the left most 3-point wire component. put one 2-point wire component on the bottom of the NPN circuit across the 1-point wire component. Put the light sensor in the middle and the yellow LED on the top part of the npn circuit.
3. Add the graphic panel & the battery. Place one 2-point wire component on the left most side as shown in the picture.
4. Turn the switch to “ON” position & block the light from the light sensor in the middle. The light turns off.
Congratulations! You just build a Solar controlled light.
