Here’s the contents of the breadboard. Some of this stock was ordered from uk.farnell.com but was sent by Newark, their US partner. As a result, postage costs £16 per order, so make sure you include all you need. In my case it was
- 3 breadboards for 2 more Alarms and the AlarmHub
- 3 more Adafruit Pi Cobbler kits
- 3 new sounders which are the loudest I can find that’ll work from 3.3V
- 2 more digital PIR detectors (from the UK)
Here’s the code – you can tell from GPIO_SWITCH, GPIO_LED, GPIO_PIR and GPIO_SOUNDER which device (sensor or output) is connected to which pin on the breadboard Pi Cobbler.
Here’s a bigger pic of the breadboard. +3.3v from Cobbler pin one is connected to both red lines. Ground from Cobbler pins 6 & 9 are connected to both the blue rails.
That’s all for now, both because I’m gonna have another shot (metaphorically for the moment) at the Drone, and also, there’s a minor restriction in the RPi.GPIO library which needs fixing (by me?) before I can progress on the hubs. I’ll explain more in another post.
