Simple Current Limiting Circuit using IC LM317/LM338
The Simple Current Limiting Circuit using the LM317/LM338 controls the current flowing to the load and these ICs also work as current limiters when we configure them properly. Here, power comes in as Vin and LM317/LM338 have 3 pins: input, output and adjust. Vin goes to input pin ad output pin (Vout) goes to load […]
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; as laser diode are very sensitive to current and with wrong current can damage it. Furthermore, LM317 usually gives voltage but here it gives constant current instead. Circuit Working: Parts List: Components Values Quantity Resistors […]
Simple Tilt Sensor Switch Circuit
Simple Tilt Sensor Switch Circuit control ON/OFF of LED or buzzer, also this tilt sensor work like small seesaw switch. In this circuit , inside a sensor there can be a small metal ball. When sensor stand straight the ball touch two points and then the current can pass and when sensor tilts the ball […]
Simple Door Keyhole Light Circuit
When ON, small device like Simple Door Keyhole Light Circuit gives light to keyhole, as it helps to put key in hole when light is low. Also, it uses light sensor and circuit to check light level, hence, to switch it by light we used transistor and LDR. Circuit Working: Parts List: Components Values Quantity […]
Simple Footstep Electricity Generator Circuit using Piezo Transducer
To begin with, we use piezoelectric transducers in a footstep power circuit because they convert foot pressure into small electrical power. Furthermore, piezoelectric effect means crystal which makes electricity when press or stress happen and if we press special crystal a small current comes out. Hence, Simple Footstep Electricity Generator Circuit uses parts like piezo […]
