I'm trying to learn a bit of AVR coding by using an ATtiny13 controller to drive a number of red LEDs, probably high efficiency indicator LEDs. They are controlled by a push switch, where a long press turns them on/off and short presses vary the LEDs intensity level.
At the moment I think I finished the electronic diagram, but I don't know if is correct or not.
All parts are SMD. This is a gift for a friend and due to time constrains my plan is to make sure the PCB is correct, order it at a supplier in China and during the time boards are delivered to sort out the software bit.
I think I got it right but, just for reassurance, can any of you confirm if it looks ok or not?
I'm tinkering this as a hobby so sorry if the schematic looks a bit hairy or if it contains gross mistakes.
