I found this schematic on how to construct a TENS machine.
I would like to create a TENS machine but use the arduino to control the output. Instead of using integrated circuit to control the frequency and pulse width, I want to use an arduino. Rather than having a constantly pulsing output, I want to be able to program patterns on the fly. For example, a constant current for 1 second, then a 2 second pause, then a constant 2 second current, then a 10hz pulse with 100 microsecond pulse width for 5 seconds…etc
From reading the schematic, the voltage can be stepped up using this schematic (although it was not used for the final implementation)
Would it be feasible to create this step up converter and control it using the arduino?
