A linear dimming controller
An AC voltage of 30V is rectified. The positive terminal is connected to a fuse and a 100W bulb, while the negative terminal is connected to a thyristor. A Zener diode provides a stable bias voltage. A variable resistor (VR)...
touch sensor switch using inverters
This touch sensor switch is designed using inverters (N1, N2) and several common electronic components. In the standby state, a signal is produced by the oscillator N3/N4 at the inputs of N1. When the touch sensor is activated, the hand's...
Capacitive Touch Sensor
For this special Halloween project, a spooky candy bowl was created that lights up when an unsuspecting trick-or-treater reaches in. While similar devices exist, many utilize complicated proximity sensors. The approach taken here is simpler, making it a suitable DIY...
lamp dimmer
This is an advanced dimmer circuit design that allows the triac to be triggered at lower voltage levels. Typically, the triggering voltage for a triac is approximately 70V; however, this circuit enables triggering at around 35V through the incorporation of...
AC Light Dimmer (isolated control)
This is another AC light dimmer, with the primary distinction being that its control circuit is isolated from the AC line, making it much safer to use. The circuit can operate on both 120V and 220V AC lines. Note: The...
Touching dimmer circuit composed of S7232
A touch dimmer circuit is illustrated in the accompanying diagram. It utilizes a finger touch control piece to enable the turning on, off, or stepless adjustment of incandescent lighting. This circuit is applicable in dimming filament lamps and for the...
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...
quick question about dimmers
Inquiry regarding the possibility of connecting two dimmers in series to achieve precise control over the light emitted by a bulb. The objective is to attain medium to high precision in light emission for a school project. Additionally, there is...
Dimmer Circuit
A light dimmer circuit is utilized to adjust the brightness of a lamp to various levels. This dimmer circuit is designed specifically for incandescent lamps, and it is not suitable for use with fluorescent lamps.
The light dimmer circuit typically employs...
