I've been using this paper to build an arduino-based potentiostat.
Development_of_a_low-cost_Arduino-based_potentiostat.pdf (850.7 KB)
I've made all the connections as shown in the circuit schematic but I can't figure out how the batteries are connected. All the connections to to pin 2,3 and 6 of the op-amps but are any additional connections to op-amps I need to make that are not shown on the schematic?
Here's what my circuit looks like.
Looking at the code, I was wondering how steptime was being calculated in milliseconds in Fig 7 of the paper. For polarization experiments, step size is always increased in the units of mV/s but I am stumped.
I've never really used arduino before I would really appreciate it if somebody helped me understand this. Thank you
