The 4 channel AC Dimmer is designed to control the alternating current voltage for 4 independent loads, which can transfer current up to 4A. In most cases, Dimmer is used for adjusting voltage levels and turning the power ON/OFF for lamps or heating elements, it can also be used in fans, pumps, air cleaners, e.t.c. Lately, Dimmer has become an often used decision for 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 effectively with filament lamps. 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 ( discharge lamps) do not support dimming. The power components of dimmer are isolated from the control part, to exclude the possibility of high current disruption to a microcontroller. 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. the 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. You can download RBDDimmer.h library and a few examples in «Documents» or on GitHub. We are constantly updating our library, so we recommend checking for website updates or subscribing to our newsletter. Dimmer is connected to dino 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. Note that Zero requires connection to designated microcontroller pins (which are different depending on the model of Uno, Nano, Leonardo, and Mega) since it is tied to microcontroller interrupts. ATTENTION: With dimmer can use only DIMMABLE LED BULB. The simple LED bulb, luminescent lamp or any other lamp with built-in power regulator CAN’T to dimming! Which way you can use the dimmer? Dimming is an easy way to enhance a room or create the right light for any activity. Make your home project for Light control with Adino and Dimmer. With a dimmer, you can control light automatically: At night, switch on and off lighting smoothly and comfortably for your eyes. To adjust the lighting level depending on light brightness from a window. Create your comfort with a sensor. Save energy on lighting, when have is daylight from the street and when it is necessary for you the muffled light in a corridor or in the children’s room. Start Your Smart Home with Adino Light Dimmer In the kitchen, lower lights for dining In the family room, brighten lights for homework, then dim for movie night In the bathroom, dim lights to gently start your day In the nursery, dim lights to check on a ing baby Control with voice Tell your voice assistant (Siri, Alexa, Alisa) what lighting you want for viewing of the TV, for kitchen or a workplace, in the children’s room. How does it work? Step 1: Connect a Dimmer to your microcontroller board (any micro controller) Step 2: Download examples and library from GitHub: https://github.com/RobotDynOfficial/RBDDimmer Step 3: Create an awesome project with more functions and controls. Step 4: Joint to a DIY community.
