Arduino Touchscreen Auduino

Continuing my experimentation with my touchscreen Arduino, this project adds five touchscreen slider potentiometer inputs to my Auduino granular synthesizer. https://youtu.be/O5qaZX_7GSc Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main concepts used … Continue reading Arduino Touchscreen Auduino →

Arduino Touchscreen PWM Sound Output

Somewhat inspired by Daphne Oram, the thing I really wanted to do with my touchscreen was to use it to draw a waveform. I now have all the bits and pieces I need to do this, so in this project I'm combining the touch screen with PWM sound output and the "drawing" idea from my … Continue reading Arduino Touchscreen PWM Sound Output →

Arduino PWM Sound Output – Part 2

My previous post looked at all the theory of using PWM on an Arduino and finished with an example showing how to use Timer 1 to generate a PWM output on pin 9. This post provides an alternative set of PWM routines that allows you to generate an audio signal on pin 3 using Timer … Continue reading Arduino PWM Sound Output – Part 2 →

Arduino Touchscreen MIDI Controller – Part 2

Here is another format for my newly found cheap touchscreen MIDI controller. This time, presenting twelve virtual "slider pots" for use as MIDI controllers. https://youtu.be/FHu0BoCBEAw Warning!

These are the key Arduino tutorials for … Continue reading Arduino Touchscreen MIDI Controller – Part 2 →

Arduino Touchscreen MIDI Controller

I picked up a cheap touchscreen display online, but it wasn't easy to work out how to get it all working. Full details can be found here, so having got to this point I thought I'd start to explore its use as a MIDI controller. Here are some follow-up projects based on this touchscreen: Arduino … Continue reading Arduino Touchscreen MIDI Controller →

Arduino Twitter Follower R2R Tones

One thing I wanted to do as a follow-up to my Pico MIDI (H)Arp was to use some data from the Internet as the source for some generative music. This post is my first try at taking my Twitter follower data and turning it into sound. A follow-up project uses a Raspberry Pi Pico to turn … Continue reading Arduino Twitter Follower R2R Tones →

Arduino MIDI Slider OLED R2R Waveform Generator

This project moves on a step from my Arduino MIDI Slider R2R Waveform Generator and adds a small 0.96" OLED I2C display. https://youtu.be/MGwdu017e00 Warning!

These are the key projects for the main concepts used … Continue reading Arduino MIDI Slider OLED R2R Waveform Generator →

Arduino MIDI Slider R2R Waveform Generator

When I first started looking at using fader/slider potentiometers I always anticipated using it to generate waveforms for my Arduino MIDI R2R Digital Audio board. But as that is currently part of the Lo-Fi Orchestra, I decided I'd build a new one, hence the diversion into using PWM first whilst I decided exactly what to do. … Continue reading Arduino MIDI Slider R2R Waveform Generator →

Arduino MIDI Slider PWM Waveform Generator

This is a short update, to demonstrate the MIDI version of my Arduino Slider PWM Waveform Generator. A future project shows a similar system using an R2R ladder. https://youtu.be/chMNcMcGbXY Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key … Continue reading Arduino MIDI Slider PWM Waveform Generator →

Arduino Slider PWM Waveform Generator

Having finally been through the details of PWM audio output, I can now link this up with my 16 slider potentiometers and start creating more complex waveforms by actually "drawing" out the wave with the pots. https://youtu.be/PbkMxU_cBL0 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for … Continue reading Arduino Slider PWM Waveform Generator →
