Hello Astro1234,

Yes this should be easy enough. all you have to do is collect the number from the keypad and then shift 1 by the number.

output = 1 << number

You might have to subtract 1 from number otherwise this will light LED 1 when number is equal to 0, LED 4 when number is equal to 3.

for example in pseudocode

Decision number > 0
Yes: Calculation output = 1 << (number - 1)
No: Calculation output = 0
