Circuit Working: Parts List: Type Value Quantity Resistors 15Ω 1/2W 1 1.5Ω 1/2W 1 1k 1/4W 2 Semiconductors […]
Solar Tracker Circuit
Think like small helper robot for our solar panels. Solar Tracker Circuit works like smart assistant which helps solar panels to always look at sun. Sun moving in sky the whole day. This circuit have sensor it sees where sun goes and change panel direction by itself. When panel always faces the sun it get […]
Outdoor Garden Solar Lights Circuit
Imagine small suns making light in our garden at night. This Outdoor Garden Solar Lights Circuit works like small power house for our garden flowers. In daytime solar panel take sun energy and put it in battery. Then night time come smart circuit take that energy and make LED light ON so our garden stay […]
