summary

A breadboard is instrumented with row-level ADCs, LED bars and a web client that scans at 200 Hz and routes measurements through a CC3200 multiplexer chain. The system builds a virtual breadboard, runs checker functions that flag reversed LEDs and off-by-one wiring, and graphs signals (example: 1 kHz transient view). Float detection pulls rows down to avoid spurious readings. An informal 7-user study (mostly novices) finds faster diagnosis, with limitations: no arbitrary external power, cumbersome virtual placement, and simplistic checkers for advanced use.
