Re: Anyone working on HD44780 library?

I do get something now but I still have to lay it almost completely flat just to see something, the blue potentiometer on the back is already fully open...

Re: Anyone working on HD44780 library?

Any of you ever had the issues that the backlight on/off does work but nothing appears on the screen?

Although I bought it as a v3 but it looks light I got http://arduino-info.wikispaces.com/LCD-Blue-I2C#v1

Re: Wemos D1 Interrupt trouble

awesome! thanks that did indeed fix it although I still don't understand why this toggles the blue led on the chip itself.

Wemos D1 Interrupt trouble

I'm using a Wemos D1 mini v2 and I'm trying to hook up a 4x4 keypad via a MM74C922N chip which sets a pin to low when a button is pressed. I figured I would use an interrupt to set a bool to True but the only thing that happens is it turns on the LED on the ESP chip... I'm new to the interrupt way o...

Re: SCT-013 values

I'm using the SCT-013-030 which should have a 62 ohm build-in and is 1800:1 ratio based on http://webmeteobox.ru/docs/SCT013-030V.pdf I made my circuit based on the design below but with different resistors. http://myelectronichome.altervista.org/joomla/images/FotoPerGliArticoli/Circuito_per_collega...

Re: SCT-013 values

It is indeed 230/240V AC but since my electric bill is quite high and I don't know why so I thought I would measure it. Since I'm not sure wetter to place it over the blue, brown or both I tried all but same difference in the readings. You clip the CT around the "live" conductor. That should be the...

SCT-013 values

Hey Guys, I hooked up four SCT-013 (-030 / 30A) with a CD4051BE to the ESP8266 (NodeMCU). The CD4051BE is only to expand the amount of analogue interfaces. I hooked it up to the 4 groups in my fusebox but I think I'm getting crap readings. Anyone any idea? You can find the values here: https://thing...

Re: Astral port/alternative

Awesome! thank you so much!

As soon as I have the time I'll port and publish it and later on try to add the twilight phases. The lunar phases might come in handy to set the lights when it's a full moon.

Re: Astral port/alternative

That would be awesome! Does is support twilight phases? and (even more important) would you like to share it?
