Couple it with logic level NMOS and a few more components can be skipped. Is there anything you could recommend to show up the flaws of the software PWM? Main problem with software PWM is usually if you try to dim to a very low light level, such as fade to black. Chip used in the featured article is great since it has 16 PWM channels, so is easily expandable. Depends on what frequency and resolution you want. I like having at least bits to get a good resolution in actual perceived brightness.

Couple that with a high enough frequency and you will get the ESP to spend most of its time in interrupts. The module works in the network as an ArtNET node, so that it can be controlled by a host of software. I cannnot way for my brother in law, who works as an LJ, to come with his console :. Most of the code is not mine. Also, make sure you do not make the same mistake as I did: this code leaves ESP in dual mode, so it acts also as a WiFi access point with default credentials.

It is not only rather insecure, but then the additional WiFi shows up around the house. Unfortunately, my device is rather inaccessible now…. This site uses Akismet to reduce spam. Learn how your comment data is processed.

Search Search for:.While trying to make my household more sustainable, I was exchanging halogen bulbs for led lights.

There are plenty of alternatives available, to replace any type of light bulb. While doing this, I came across the following problem: I had a light fixture which used 7 12 volt halogen bulbs, each 10 Watts. This light was controlled by a dimmer, which worked fine. When I exchanged the bulbs for 12 volt led lights, each 1 Watt, the dimmer worked badly: the light was flickering, and the dimming somewhat erratic. This is a problem with a lot of classical dimmers: they have a minimal power rating, which they need in order to work.

So, based on my domotics system, I decided to exchange this manual dimmer by a new one, which would have the added advantage of being able to be controlled remotely. I want to use this dimmer for another fixture which has 12 bulbs, each 2 watts, which gives a maximum of 2 Amps, so that is also sufficient.

Pin 0 is also connected to the on-board red led, so I could check the function of the button on the encode by watching this led. Pin 16 is used for the PWM output, and I connected this directly to the green led on the Sparkfun encoder. This Gate is pulled high to 12 volts by a 4. I used the DC-DC converter to convert the 12 volts to 5. I could have used 3.

What is the command to turn off and on please? Reply 8 months ago. The commands are as stated in the sketch: 'ON' and 'OFF' without quotes, of course to turn the led on and off, and an integer to set the brightness.Not a member? You should Sign Up.

Touching live wire or powered ON board is danger and not advisable, it may cause death, please avoid it. Please Switch off the mains before you make or change connections, be very careful. If you are not sure of anything related to the AC supply lines, please call an electrician ask and him to help you with it. Do not attempt to interface with mains unless you have adequate training and access to appropriate safety equipment.

Never work on high voltages by yourself when you are alone.

These are used for resistive, and inductive loads, such as incandescent,cold cathode and low voltage inductive lamp sources.

Note that not all electronic transformers used for low voltage lamps are suitable for dimming by Triac or Thyristors dimmers. In case of Thyristors you need 2 of them as Thyristor is a Unidirectional device and because AC power flows in both directions! Why using Thyristors? One of the reasons is that they are available in higher power ratings than Triacs and are more robust. A A to 1kA ratings is something common for Thyristors. Usually you will find this kind of Thyristors in Industrial applications, not exacty a hobbist part.

BTAB is a good example. And this is because of the way the dimming process is going and depending on our own ZCD zero cross detection function. In our case zero cross detection is done by the biphase optocoupler as in the schematic below. The number of cycles in one second is called the frequency. The value 50 or 60Hz is dependent on the countries power system.

The current alternates back and forth changing direction at the zero point. If we will to look at the waveform yellow with the Osciloscope it would appear as a sinusoidal shape. Drawing a line through the middle and this is what is called the zero crossing point. At this instant in time no current is flowing in either direction. By chopping the waveform at the zero-crossing point, smooth dimming can be achieved without the lamp flickering. This turning on and off of the power device occurs every time the mains crossing point is reached half phaseor times per second 50 or 60Hz.

For very simple reasons. But this is not affecting at all the general view of the process. MPDMv3 Software. Define used GPIO pin :. As you have seen above on the Osciloscope, zero crossing is the moment when the sinusoide goes through zero. After each zero crossing there is one full half of the sinuswave available to send through the Triac to the Load. So what the software needs to do is to detect the zerocrossing, and then wait for a set amount of time on that sinuswave to switch on the TRIAC.

We have a 50Hz VAC that means is 50 waves per second. That means that after every zero crossing detection there is a 10ms period that we can regulate.

If we switch Triac directly at the beginning of that period, the load will receive full power If we do it at the end of that 10ms period the load will receive none and if we do it halfway, the load will receive half power.

It is Triac driven and intended to be used for lighting control. Tested and working ok with standard lightbulbs incandescent lamps or the new Halogen ECO. For LED or fluorescent lights you need to check first that they are dimmable units. All the proper Zero Crossing Detection and processing functions are done driver side, onboard!
