Vegaswinner does it with 256 steps 8bit (not so very smooth). I do it with 4096 steps 12bit (very smooth). I dont use a lm358. There is no reverence voltage. I do not convert the 5V PWM signal to 0V-10V. No analog bullocks. I switch (connect/disconnect) the dim+ and the dim- wire of the driver...

I am hurt so badly now. My tears fill the river "Maas". Will I ever get over this? And of course 4096 steps PWM is way too much. No one could handle 4096 steps. Oh, I dont feel hurt anymore. I already got over it. I do this for fun and now I do this to prove I build better than u. I like to...

Okay??? I have to check what real styles is and I have to take a nap now first. I am from the netherlands and it is 1:05 pm here. Glad to talk to u later.

240 meanwell drivers to dim simultaniously? I am dutch and have poor english/american language technologie. What do u want to accomplish?

Oh that is true. Maybe....... very maybe (sorry for the poor language), I can make a complete assembled (on a neat pcb), programmed, 16 channel, 12 bit, smooth running, internet controllable (or only via wifi homenetwork or only with the touchbuttons and a menu on the lcd) and ready to go 10V...

If u want a duty cycle of 50/50%. Just say to the chip 50/50% and the chip makes the required PWM signal till u give a new command like 60/40% then the chip makes the new required PWM signal. Just send the commando via i2c databus to the chip. The chip communicates with i2c.

The pca9685 is the best for PWM. It has 4096 steps (12 bit), 16 channels and it drives it self. Set it to a certain frequency and duty cycle (once) and it runs by it self. It does not consume mcu/mpu sources. And the best thing is that it is produced by NXP from the netherlands. The "thing"...

I win because I prototype just for fun. Not for the fame or the money.

:wall:

Why not? The data sheets of the hlg drivers says the the drivers can dim through resistance (10K-100K+), voltage (1V-10V) or a 10V PWM signal with a frequency between 100Hz and 3KHz. The PCA9685 PWM chip is set to 1KHz and outputs 5 volt, 12 bits PWM. I use that signal to switch the 10 volt +...

The experiment will be done by me soon. I am curious about the results.

I am planning to use a raspberry pi for complete automation too. All lights connected via WiFi to the raspberry and the raspberry controls the lights. I want to make it possible to change the settings of the lights via internet (wan) in the raspberry. If internet connection fails the lights will...

That is one esp8266. All useable pins used for spi (4), i2c (2) and onewire (1). The lcd works via an i2c port expander (the black ic). the relais and buttons work via the i2c port expander also. The little blue thingy is an level shifter for communication between the esp8266 (3.3V) and the i2c...

Dimmable via internet (PWM). 60 Watt 6500K CXB3590 (highest bin CXB3590-65E-CD-N0H)and 200 Watt 2700K CXB3590 (highest bin CXB3590-27G-CB-N0H) to make different color temperatures by mixing. Make schedules like sunrise and sunset and lenght of day. Every led has an ds18b20 temperature sensor on...

And vote for Manas Manohar. He can win education a trip to NASA spacecentre and Disneyland. This 15 year old boy already build that internet grow room controller.

At least they can dim to 0% instead of +-10%. :roll:. Everyone seems to have their own prioritys.

Another thought...... It would be great to log powerusage of the lamps. Because the lamps use various power (dimmable), it would be great to see how much KWh/W each lamp uses. I need to implement a watt meter in each lamp and send the data to the control website. The website does the conversion...

I know that there are many ways to achieve things. The best ways are the ways that work and are simple and cheap. A transistor and base resistor is cheap and simple. Cheap is always a good thing and simple things don't tent to break quick. I am not going to share because i write the libraries...
