Driving a Blinkt! as an IoT device


I managed to buy a Raspberry Pi Zero when they first came out in December 2015. This was not easy since they were very scarce. I also bought a first-generation case from Pimoroni and some 40-pin headers. With the Zero this header is not pre-installed and it’s necessary to solder it onto the Pi yourself.

I have had various project ideas for this Pi Zero, but had not decided on one until recently. Within the last month or two Pimoroni produced a device called the Blinkt! which has eight APA102 RGB LEDs and attaches to the GPIO header. This costs £5, just a little more than the Zero itself.

My plan was to combine the two and turn them into a status indicator for various things going on that needed my attention.

Long notes

I have written out a moderately long set of notes for this episode and these are available here

You light up your life

I'm posting this comment with the sole purpose of turning Dave's light on. :) Super cool episode Dave! One of these days I'll use the IO pins on one of my Pis. I have an LED-related episode in mind too, though a very different kind. Once the semester is over I'll stop just lurking and post a new episode. Thanks for a great show.

It worked!!

Thanks Jon,

As someone who studied Operant Conditioning back in my university days I am rather aware that I might have constructed a means of conditioning my own behaviour! I should work on a food reward dispenser system of some kind perhaps.

Looking forward to hearing about your LED project at some point too :-)
