Face detection enrollment in a persistant storage

Hello there, I started fiddling around with the Esp-who repository and compiled this in a "TTGO T-Camera ESP32 Wrover2" board and it works very well. So I though about extending the examples in some real life-device, like for example, enrolling faces with a name in a persistant storage. And do somet...

Doing a RGBW lamp, White channel PWM ?

just wanted to know what is the right way of doing a RGBW lamp: https://hackaday.io/project/163672-esp32-meshkit-unexpensive-rgb-led-panels Started a project in Hackaday to make your own ESP-Mesh lamp and I'm using just the RGB PWM outputs. I though it would be possible to combine all Red, Green and...

Re: Inverting PWM signal on RGB Light

Thanks! Another option I found to separate the Logic from the Led power line, is to use one 74HC125 Quad Bus Buffer Then you have the advantage of not soldiering 3 different components with a max output of 35 mA which is enough to power quite a lot of 5mm leds (35 in my case) But I will try invertin...

Re: Inverting PWM signal on RGB Light

Thank you very much costaud! That looks like the smartest solution since I can use the P-Channel mosfets. I though also that we can power the RGB Channels directly from the GPIO, taking in account the they don't consume more than the allowed mA. Will start a project in Hackaday to make your own smar...

Inverting PWM signal on RGB Light

Hello all, I'm testing the Light example https://github.com/espressif/esp-mdf/tree/master/examples/development_kit/light I tried to compile this and attach an RGB in the Gpios and works great: https://twitter.com/martinfasani/status/1090168545026150400 And as I have a lot of P-Channel mosfets in my ...
