Tell us about yourself!
I used your code for this project. This looper only has a little noise from the relays as you mentioned, but this goes away with a buffer before. I didn't use any decoupling capacitors either. one of my distortion pedals creates a very small going noise, but it's too quiet to warrant using decoupling caps. Thanks for posting this project, it so much fun and very hand to have. On my pedal board.
This is my build of the 5 pedal switcher.I couldn't find the right size of enclosure. This one was hard to fit everything in. but i got it all to fit anyhow. I've added an extra footswitch / LED to add an extra feature, like a boost or bypass all. I just havn't hooked it up yet. But the switcher is done for now.
well done! can you please share your arduino code? i like how you can program the preset without using a rotary switch. thanks!
One more question for you. After programming a preset to footswitches, should the relays go into bypass after hitting the switch again? Or does one of the present have to be set to all pedals off, to get a bypass mode?
CarraN, how hard would it be to change this project, so that there is no read / write / select switch. But instead another momentary on/off footswitch. That would change from read mode to select mode. And the method of storing the preset was holding down the desired footswitch for 3 seconds?
