| Feb 28, 2018 at 13:40 | comment | added | Jasper van den Boezem | Thanks for your answers. I'm relative new to this world. I will try to draw one but never did, so will take me some time I guess.. It is 4.0Ah indeed.. Basically I have a Raspberry Pie, an 18v power supply, and 30 leds which I want to control to create something like this: bertspaan.nl/led-wheel | |
