Each fault really happens in the simulation. Trigger one, watch the figure, then read why.

Light the centre of the matrix and an LED on ring 1 together, then turn them off, once a second.
| Pin | Connects to | What it does |
|---|---|---|
P1 | LED long leg, through 470 Ω | Drives the LED |
GND | LED short leg | Ground |
Sensors and actuators this board drives, with the real connections.
Clip ring 1 to the LED's long leg through a 470 Ω resistor and the short leg to GND: about 3 mA.
| Part pin | Board pin |
|---|---|
| A | P1Wire colour yellow |
| K | GNDWire colour black |
A V2 pin gives only 1 to 4 mA. Never connect an LED without a resistor.
