Simple Solar Garden Light Circuit using One Transistor
Simple Solar Garden Light Circuit using One Transistor, uses one special switch and a sun power to turn on LED at night. Also, when sun goes down the light turns ON by itself and when sun come back the light turns OFF, like a magic! Circuit Working: Parts List: Components Values Quantity Resistors 1k, 47Ω, […]
How to Illuminate 18 LEDs from a 3.7V Battery
In this post for How to Illuminate 18 LEDs from a 3.7V Battery we need to power 18 LEDs with 3.7V battery like a small light party! Also, to light all LEDs well we need smart plan; we have to make small LED groups and connect in clever way. So use series in line and […]
Buck Converter Circuit for 1 Watt LED Driver
Imagine we have a strong water hose of 12V, but plant need soft sprinkle with 3.3V to 3.5V, then in that case a Buck Converter Circuit for 1 Watt LED Driver is like adapter for hose. Also, it makes pressure low and is good for plant and it control water flow like current, so plant […]
Simple 1.5V White LED Driver Circuit
Simple 1.5V White LED Driver Circuit is like power translator; it takes power from battery and changes it to right voltage and current for LED. Furthermore, this helps LED shine bright and safe, but without driver LED may be it might dim or may burn. Circuit Working: Parts List: Components Values Quantity Resistors 33k, 470Ω […]
