Arduino with Multiple Displays – Part 3

Whilst messing around a little more with my Arduino with Multiple Displays – Part 2, I've optimised the code a little and found out a bit more about these displays! In this part, I'm actually using a PCB that can hold four displays, powered by a Waveshare Zero device. More on that here: Waveshare Zero Multi … Continue reading Arduino with Multiple Displays – Part 3 →

Arduino with Multiple Displays – Part 2

As I mentioned in my last post on Arduino with Multiple Displays I'm going to look at other microcontrollers too. This post takes a wander through my Waveshare Zero and similar format boards that each support one of the RP2040, ESP32-C3 or ESP32-S3. Warning! I strongly recommend using old or second hand equipment for your experiments.  … Continue reading Arduino with Multiple Displays – Part 2 →

Duppa I2C MIDI Controller – Part 4

This is revisiting my Duppa I2C MIDI Controller this time using a Waveshare Zero format device. Part 1 - getting to know the devices and testing them out. Part 2 - adding MIDI to the LED ring and I2C encoder. Part 3 - adding normal encoder, plain potentiometer, and endless potentiometer control. Part 4 - revisits the idea with … Continue reading Duppa I2C MIDI Controller – Part 4 →

Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2

This revisits my Forbidden Planet “Krell” Display – MIDI CC Controller using my Forbidden Planet “Krell” Display PCB with a Waveshare RP2040 to create more of a "all in one" device. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! If you … Continue reading Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2 →

Waveshare RP2040 Matrix MIDI Monitor

Following on from my ESP32C3 OLED Mini MIDI Montor and Waveshare Zero, Pimoroni Tiny, and Neopixels this project uses a Waveshare RP2040 mini Matrix display. This is largely the same pinout as the other Waveshare boards, but includes a 5x5 programmable LED (i.e. neopixel-like) matrix. https://makertube.net/w/cdxAJJvsqsPKrzVg6xWodD Warning! I strongly recommend using old or second hand equipment for … Continue reading Waveshare RP2040 Matrix MIDI Monitor →

Waveshare Zero, Pimoroni Tiny, and Neopixels

I want to revisit my Forbidden Planet “Krell” Display looking at an alternative way to do the electronics. In particular, I'm looking at how I might embed a microcontroller in each display. This post is a short diversion into the world of some Waveshare "Zero" format devices and a bit of background on driving programmable … Continue reading Waveshare Zero, Pimoroni Tiny, and Neopixels →
