Changing the functionality of a foot switch using transistor - Looking for some advice from the pro

@Grumpy_Mike

Hello Mike,

First of all a lot for your help, I really appreciate it.

  1. The picture below shows the jack input I am plan on using :

From the reference manual.

  1. The circuit I sent earlier with the tittle Boss FS-6 Clone is for a 2-switch foot-switch. I am trying to construct something like the FS-5U below

  1. The original Boss FS foot-switch have a polarity switch at the back (see photo above). The switch toggle the foot-switch between Normally-Close and Normally-Open. I don't need that what I am building (always Normally-Close is what I need - unless I press the foot switch the tip and sleeve are connected)

  2. The footswitch I am using is a DPDT (Double Throw Double Pole). So I am hoping to create a Normally-Close circuit for the RC5 pedal and using the same DPDT,create a Normaly - Open circuit to trigger D8 on the Arduino. D7 on the Arduino will be used to toggle between what the DTDP does

  3. I am not familiar with relays (only use that one on my motorcycle when I had to change the horn).
    I wrongly thought I could use transistors for this project. So I will look up the relays and post a new circuit.

Have a great day

P.
