12V SMPS Driver Circuit for LED Strip
12V SMPS driver change big AC power from 110V or 220V into small 12V DC, also circuit is good for LED strip light. Furthermore, in this DIY project we can make cheap and strong LED driver, which can power full 12V LED strip with 100 or 200 LEDs. Important points to follow: Here, Circuit uses […]
Simple Flasher Circuit using LED and LDR
This simple flasher circuit uses an LED and an LDR to create the flashing effect; as the light level changes, the LDR changes its resistance, which controls the LEDs blinking. Hence, there is no need for big chips or transistors but still the LED blink happens, also it uses simple parts like resistor, capacitor and […]
