Now it works with IR + PIR control. I had to sacrifice the onboard LED for that. Why aren't there any DIP-10 chips?

Plugged right into the ISP header.

Quite small PIR sensor

Sensitivity is not adjustable. Range is a couple of meters. It needs some external intelligence to be useful as a lamp controller (off-time hysteresis).

By changing the position of a 0-Ohm resistor (from L to H) it can be adjusted to re-trigger-able mode. When using a micro this is not really necessary.

Completed the first board of the 2nd revision. The 3rd revision has some minor changes, more suitable footprints and better locations for parts. This one works nicely too.

Total power consumption is about 6mA - with the LED on (powered by the pull-up). So far the only power-relevant code shuts off the analog comparator. Maybe the ADC should go to sleep as well.

IR receiver module added

It works reasonably well, although in real-world applications the IR sensor would probably have to be placed elsewhere (i.e. add wires).

If there should be a reincarnation of this board at some point, it would probably have dedicated PWM drivers.

To allow for further shrinkage, I will have to use a tinier AVR package and probably get a hot-air thingy.
