Hello,
This is my first dive into arduino and I have very little prior experience aside from rudimentary coding and breadboarding.
I am trying to set up an adhesive electrode pad to be an output. The electrode has a female 2mm pin connector. I looked everywhere online for a male 2mm pin to bare end wire but could not find one. What I found instead was this 2mm male pin connector to 3.5mm jack. I also found this breadboard friendly stereo jack that would be able to receive the 3.5mm end of the wire.
My question is, essentially: would it be feasible to connect the electrode to the breadboard using this configuration? I am trying to write a program that will receive an input signal from a pressure-based sensor and send a variable amount of current to the adhesive electrode based on the amount of pressure detected.
A second and implied part to this question is: can anyone think of a better way to do this? Especially a way that would require less components? My end goal is to condense and move the project from a temporary breadboard to a veroboard.
I would greatly appreciate help, advice, and any suggestions you might have. Thank you
Cut the jackplug off the 2mm to jackplug lead and solder on a couple of leads with Dupont pins on them to go into the breadboard. If/when you move from breadboard to Veroboard unsolder the wires that go to the Dupont pins and solder them onto the Veroboard
send a variable amount of current to the adhesive electrode based on the amount of pressure detected.
What sort of voltage and current is involved ?
Thanks for the reply! Not sure about what voltage/current is going to be involved, but most likely pretty low. Will need to do some testing as the adhesive pads will be exposed to bare skin and I need to make sure that it is safe for medical application. There needs to be enough current for sensation without breaking the pain threshold

Good luck with the testing. Where on the body will the pads be placed ?
When I had my nerves/reflexes tested, the Doctor set
the "test set" to between 20 and 25 milliamps. I didn't
ask what voltage he used. He applied the electrodes
to my forearm and I felt the mild shocks.

The pads will be placed on the upper arm, so I'll probably try a bit less than Herb suggested because I just need stimulation and not shock. Thanks to both of you for the advice
