ElectroCookie Circuit Debugging Expert

I have a custom circuit already wired up on an ElectroCookie prototyping board, but it refuses to behave the way the schematic says it should. I need a seasoned set of eyes and hands to track down the fault, correct it, and prove the board works reliably afterward. Here’s what I expect from you: • Inspect the existing ElectroCookie layout, trace connections, and identify any wiring or component errors. • Suggest and implement the fixes—whether that means swapping components, re-routing jumpers, or revising the layout. • Verify the repair with scope or multimeter readings and a short video or photo set that shows the circuit running as intended. • Provide an updated schematic (KiCad, Eagle, Altium, or even a clear hand-drawn PDF) that reflects the final, working design, plus a brief fault-analysis note so I know what went wrong. If you are comfortable probing live boards, reading datasheets on the fly, and know the quirks of the ElectroCookie platform, this should be a quick turnaround job.
