Only bid if you have worked with Arduino or are aware of technical specs.
I need a circuit designed that will have two electrodes, medical grade. They will need to have 9V and about 1.2-1.4mA going to the skin from them. They need to have the ability to be controlled for the waveforms, most likely through PWM pins, so I can control the electrical signals being sent to either electrode independently.
I will want guidance on acquiring the needed parts, also. NO PROGRAMMING IS REQUIRED. I just need the circuit.
I will want to order, build, and test the schematic parts out before payment is to be released.
