I did a few electronics projects for myself and for school which I intend to post here if I have the time. I will focus mainly on the schematic captures and perhaps a little bit of the documentation may be posted here in the form of a pdf document.
Interfacing the digital logic and timing from a counting System with the AC mains circuit to turn on the incandescent lights synchronously and appropriately.
Automatic day-night sensing using an optical sensor (like an LDR). This circuitry will draw power from Subsystem 1 which supplies 5 V.
Adjusting the brightness to the load in accordance with the ambient brightness sensed using a triac for phase control dimming.
This was meant to be a practical task for a digital systems module at university. It was surprisingly challenging and took a long time to debug. I managed to program all functions from scratch. It took me several days to perfect it.
