Rebuilding a scrolling sign project that I originally made from 74HC595's. Started a new circuit from scratch using MAX7219 chips. I was following this video on youtube as closely as I could https://www.youtube.com/watch?v=v1vRjOU_pGA&t=608s
I bought the MAX7219s. I cut my sign into 8 segment sections. I’ve wired up a breadboard test with 8x7(I only have 7 rows), and just the first 24 columns just to test out the idea.
I’m lost on something. I don’t understand how to wire the capacitors in the circuit correctly. I’m sure this is 101 for anyone into electronics, but I’m quickly over my head without a good foundation in electronics.
If I’m understanding it correctly, 5v is supplied to pin 18 of the max with a resistor between the pin and the 5v power supply.
Then pin 19....this is where I get lost. I am connecting 5v directly to pin 19, and in that same flow, adding one 10uf capacitor, and one .1uf capacitor. One leg of each on pin 19, then the other to ground. For the 10uf, I have the striped side with the ‘-‘ on the negative.
Does it sound like I’m doing this correctly?
