Hello, before I continue I would like to let you guys know that I'm a novice using Circuit wizard.

I'm using the Genie E18 board (it's a must) and I'm trying to do so that I can press a certain number. For clarification, Pin 1 (row 1) and pin 2 (column 1) should result in the number 1 as it is the intersection of the two pin. However It seems that I cannot figure out how to make it so that it would ONLY be number 1 and not the rest of the numbers on row 1 and column 1 (2,3,4,7,*). So my question is how do I programme so that it would only be a CERTAIN number and not the whole 7 numbers (3 in a row, 4 in a column)?

You have to scan the keyboard by delivering HIGHs to it and looking for a LOW or a HIGH.

Can someone please show a circuit wizard flowchart to replicate this?

You need in-out for a keypad. The Genie E18 has 8-out and 5-in. You have to show how the keypad is wired.

No, you are the only user of Circuit Wizard - I've never heard of it.

I've watched the videos and I was wondering if you have any ideas on how to use the same concept but on an E18 Genie board?

We need to know the keypad configuration.

I think this whole thing is beyond your capabilities.

Bringing this thread back to life, why doesn't this work?

You cant make lines high and low. You have to have inputs and you need pull up resistors.
You need 5 years of electronics study before starting to develop a program for a keyboard.
