Led dimmer circuit with potentiometer. Check the electronic components you need here. When the potentiometer is turned all the way to the side where it has a resistance of near 0ω the led shines the brightest because the circuit has the least amount of resistance at this point so it produces the greatest amount of current which is fed into the led. Voltage variation fades led when you rotate the knob of the potentiometer resistance decreases and the current starts flowing. These voltage levels are sent to the transistor s base with a 10k current limiting resistor.
Construction and testing for led strip dimmer circuit. Connect the other end of led to ground in series with a resistance. More than 800 original brands mo. This potentiometer will be used for varying the voltage for dc dimmer circuit.
If you have a controller with a 0 10v output signal consider using the eln that can work with that type of circuit. Resistance can be in range of 120 ohm to 4 7 k ohm. Schematics for strip dimmer circuit. Simple resistance dimming with some shortcomings.
The potentiometer creates a voltage divider in the circuit. After watching this tutorial you can control or adjust your led b. In this way the led dimmer circuit with potentiometer will work. Control your leds or led strip by using your own led dimmer circuit diy with potentiometer.
This is how the circuit works. And when we rotate the potentiometer then it creates different voltage levels for the led dimmer. This is an instructable that teaches you how to use a potentiometer to dim an led. The most common issue is people trying to use a standard triac type wall mounted dimmer with a mean well led driver that has the 3 in 1 dimming feature.
