Hola, mi amigo! I looked through my PCB design, then realized “This isn’t going to work.” So I used my brain, then started over with the basic format, where each key should be.
The improvements I made today:

• Re-designed the basic structure of the keyboard.
• learnt how to connect the diodes properly.
• Most imp: don’t do stuff when you’re sick and have a fever, it will reduce productivity.
