Description
The AC Dimmer is designed to control the alternating current voltage, which can transfer current up to 600V/16А.
In most cases, Dimmer is used to turn power ON/OFF for lamps or heating elements, it can also be used in fans, pumps, air cleaners, etc.
Lately, Dimmer has become an often used decision for the smart home systems.
For example, when you need to smoothly change the light brightness.
The lamp is slowly turning ON or OFF, creating a comfortable atmosphere.
Dimmer works most effective with filament lamps.
ItÕs less stable with low brightness dimmable LED lamps, but with moderate and high brightness it will perform a solid job.
Note that luminescent lamps (gas discharge lamps) do not support dimming.
The logical level is tolerant to 5V and 3.3V, therefore it can be connected to the microcontroller with 5V and 3.3V level logic.
In , dimmer is controlled with RBDdimmer.
h library, which uses external interrupts and process time interrupts.
It simplifies the code writing and gives more processing time for main code.
Which is why you can control multiple Dimmers from one microcontroller.
Dimmer is connected to controllers via two digital pins.
First (Zero) to control the passing of Phase Null of AC, which is used to initiate the interrupt signal.
Second (DIM/PSM) to control (dim) current.
You can download RBDDimmer.
h library and a few examples in ÔDocumentsÕ or on GitHub.

It’s less stable with low brightness dimmable LED lamps, but with moderate and high brightness it will perform a solid job. Note that luminescent lamps (gas discharge lamps) do not support dimming.
3. Power part of dimmer is isolated from the control part, to exclude the possibility of high current disruption to a microcontroller.
4. The logical level is tolerant to 5V and 3.3V, therefore it can be connected to the microcontroller with 5V and 3.3V level logic.
5. In , dimmer is controlled with RBDdimmer.h library, which uses external interrupts and process time interrupts. It simplifies the code writing and gives more processing time for main code. Which is why you can control multiple Dimmers from one microcontroller.
6. Dimmer is connected to controllers via two digital pins. First (Zero) to control the passing of Phase Null of AC, which is used to initiate the interrupt signal. Second (DIM/PSM) to control (dim) current.
7. Note that Zero requires connection to designated microcontroller pins (which are different depending on the model of Uno, Nano, Leonardo, Mega), since it tied to microcontroller interrupts.
8. You can download RBDDimmer.h library and a few examples in «Documents» or on GitHub.
Theory:
Dimming can be achieved by Pulse Skip Modulation:
Method 1 — One or more cycles (sine wave signal) are transferred to the load while following one or several cycles are blocked.
Method 2 — Partial transferrence of each sine wave to the load.
Method 3 — Generation of modulated full sine signal of different frequency up to a few hundred hertz. This method requires specialized powerful AC generators with different modulation.
Methods 1 and 2 are the easiest to execute with the help of a Dimmer and program code: in both cases, there is a need of circuit that detects the zero crossings and can control a triac.
