This morning I spent some time breadboarding. I removed everything on the main breadboard, and started from scratch with a new layout. I thought about how to set it up so I will have enough space for all other components needed.

The SLG46826V module has a new home on the main breadboard. I will use the ICSP capabilities to program it, once the design is finalized I will write it to the NVRAM.

Now with the breadboard set up, I need to revisit the main project code. I need to read the LUT's and determine which key is pressed.

I've also been looking at the bell ringer part a little bit, and I've found an IC that could be used to make a new better PSU. Looked at gate drivers, and N-Channel H-bridge designs.
