It look easy but help us learn big and understand hard projects later. Coding: Code Explanation: Circuit Working: Parts List: Component Quantity Resistor 220Ω 1/4 watt […]
Simple Laser Diode Driver Circuit using IC LM317
One way to give steady current to laser diode is using a Simple Laser Diode Driver Circuit using IC LM317. Laser diode are very sensitive to current and with wrong current can damage it. LM317 usually gives voltage but here it gives constant current instead. Circuit Working: Parts List: Category Item Quantity Resistors 330Ω 1/4 […]
Basic Circuit for Multi-Way Lamp Switching
We can control one bulb from many places using Basic Circuit for Multi-Way Lamp Switching. Three-way switches are also called two-way and four-way switches are also called intermediate which are also used. Three-way switches go at both ends like at hallway doors. They have 3 terminals: Traveler 1, Traveler 2 and Common. Four-way switches go […]
