Rersduyt NE555LED Dimming Desk Lamp Set Kit Electronic Production Parts Set PWM Circuit DIY Welding Practice Skills Assembly
£12.17
The charging circuit uses 4056 charging IC. The 4056 is a linear charger circuit designed for potassium ion or potassium polymer batteries. It uses power transistors within the chip to charge the battery at a constant current and constant voltage. The circuit consists of three parts: charging circuit, PWM signal generator and LED light board. Battery capacity: 1200mAH This is a PWM dimming desk lamp based on 555 timer. PWM is known as pulse width modulation signal, which uses pulse width to adjust brightness. The larger the pulse width, the higher the brightness, the narrower the pulse width, the the brightness. Since heat wastes less electricity, the efficiency can reach 90%. The basic frequency of this circuit is about 30KHz, so flicker not occur. If you like DIY and just need a desk lamp, this desk lamp kit is a great choice. Get a desk lamp while practicing your soldering skills, Manufacturer: I500454621
