Simple silicon-controlled dimmer circuit diagram
A simple silicon-controlled rectifier (SCR) dimmer circuit is depicted in Figure 13. This circuit is designed to control the brightness of lights. As the resistance in the potentiometer decreases, the conduction angle of the SCR increases, resulting in an increase...
LED ramping circuit
In this circuit, the intensity of the LED varies in a ramping fashion. The circuit comprises three integrated circuits: two 555 timer ICs and one LM393 operational amplifier. IC1 and IC2 are configured as oscillators to generate frequencies of 10...
28 led clock timer
This is a programmable clock timer circuit that utilizes individual LEDs to signify hours and minutes. Twelve LEDs can be arranged in a circular formation to represent the 12 hours of a clock face, while an additional 12 LEDs can...
PWM Controller Circuit
This PWM controller circuit is suitable for managing small motors with a maximum current consumption of 2A. For higher currents, additional cooling is required.
The PWM (Pulse Width Modulation) controller circuit is designed to efficiently control the speed of small DC...
LED driven tail/brake Light Cluster
This circuit was designed on request to drive a Light-cluster formed by several LEDs that can be mounted in the vehicle as a tail and brake light. When SW1 is on, the cluster will illuminate at medium brightness. When brakes...
PWM DC Motor Speed Control
This is a circuit for controlling the speed of small DC motors; it works nicely as a speed controller for an HO or N gauge model railroad. More: The left half of the 556 dual timer IC is used as...
Mains operated LED night lamp
A simple and effective LED-based night lamp circuit is designed to operate directly from the 230V mains supply. The circuit utilizes a total of 24 white LEDs, producing an output of approximately 15W. Current limiting is achieved through resistor R1...
LED lights inside the refrigerator circuit diagram
The schematic for the LED lighting circuit in a refrigerator consists of eight high-brightness white LED lights. These LEDs are housed in a transparent white plastic tube, which is the same height as the refrigerator cabinet. The circuit receives AC...
About a PWM power inverter
A few months ago, a search was conducted for an easy-to-build PWM inverter that does not require any PIC programming. The investigation led to a consideration of a 555 PWM amplifier circuit.
The 555 timer IC is widely used in various...
