A 3×3 font for Led Matrices

For the clock project I require text to appear in a small container, that is 4×4.

Since in this 4×4 I have to add vertical and horizontal spacing this ends with a 3×3 font.

Never in my life I designed a font, and if you check my hand writing… it is horrible. Luckily 3×3 only leads up to 2^9 options, 512 different characters, and I believed I could handle this.

After writing the font in a squared notebook, I checked that other fronts already exist, and, unsurprisingly they were very similar to mine.

Arduino Clock wiring

Before any soldering or programming happens at all, I’ll need to have a general idea of what connects where.

This post presents the schematic for the Secret Santa Clock and a quick explanation of each “module” of the system. Everything from a bird’s-eye perspective that is enough for you to reproduce it.
