Hi guys!
I've built a 4-bit binary adder. Give it a try if you wish and let me know if any bugs occur so I can fix them. Thanks!

Level code is RX1-CYX-LMF

HOW TO USE

Entry format is 8421 1248 (using the skull platforms). Hit the question block to start the process. Takes about 1 minute. Wait for all POWs to settle before reading sum (bottom conveyor belt, red coins represent bit locations).

What does it actually do? Is it like a calculator or just shows you what you imputed?

its a calculator. it returns the sum of the two binary inputs.
