Power Battery Saver Circuit
This is power battery saver circuit using an IC-555 timer. The lamp is controlled with a PWM mode by adjusting of potentiometer VR1. And, PNP power transistor drives a lamp. Sometimes a light bulbs or lamp is too brightness. It is shorter lifespan and wastes too much electricity. You need just enough light only. First, you may use a variable resistor in sires. To adjust the brightness. But it does not work. Because it uses a high power. There a lot of ways to fix the problem. This is on another way you may like it. It can save the power of a battery. The…
