Attaching the components is relatively straightforward; just be careful to align the rows of pins slowly together when mating the two boards. I find it easiest to rest one set first against their mating socket, not yet inserted, and then slowly lower the other half into place and verify that alignment, re-adjusting if necessary.
- Verify that the Pin labelled 1 on the Pico WH aligns with the Pin labelled 1 on the Terminal PiCowbell, then connect the boards together carefully (insert both pin rows at the same time with even force)
- The next steps require a small flat headed screwdriver (approximately 2mm)
- Attach one wire of the Magnetic Contact Switch to the screw terminal for Pin
GPIO 13(or chosen pin)
- Attach the other wire of the Magnetic Contact Switch to a ground pin terminal (labelled
GND)
If not using a USB cable to power the Pico, then wire your connector into the Terminal PiCowbell, for example the Male JST-PH 2-pin connector wires to VSYS and GND (do not connect the battery yet).
On the next page, the firmware (software) will be installed onto the microcontroller, and then afterwards move on to configuring the Wippersnapper device and switch component, and finally setup an automated Action to send the notification message.
