Hi!
First off, I'm completely new to teensy (or similar devices) and circuit design in general which may result in me asking stupid questions... but hey, I'm here to learn!
For example, I know what a lot of components can do and how they are useful, but don't know how to hook them up in any circuit, or what resistors to use etc.
Anyway, I'm working on a project where I need an AM effect off which I can change the waveform and speed.
simply: Mic input --> amplitude-modulated amplification --> line output (to speaker or recording interface etc.)
in the end it should basically be like a code-able tremolo effect of which I can change the modulation speed and waveform with knobs.
let me first list the parts I have at the moment:
- a Teensy 3.2
- a header kit that I can solder on for breadboard use
- a small amplifier board with a built-in potentiometer (a small one you have to turn with a screwdriver)
- a breadboard and some wires to go with it
if I need anything else I'll just have to buy it somewhere. Shouldn't be too hard!
Now this was what I wanted to achieve practically:
What I want to do is basically "replacing" the POT on the amplifier board with the Teensy, so that the Teensy controls the volume output of the amplifierboard instead of the POT.
The Teensy is then supposed to modulate the volume output with an Oscillator. Ultimately I want to be able to change or morph between Waveforms (saw waves, square waves, sine waves, etc.) but that will be a coding issue for later.
my main questions for now are:
- If a Teensy can function as a digital potentiometer at all, or do I need a seperate digital pot chip for this?
- If so: how and where would I hook it up to a teensy (which pins to use and how to get them to function)
I don't know if this is too complex to ask in just one post but any help is welcome really... this is the first time I'm doing anything like this so maybe this is a little harsh for a starter project. OR maybe it's much easier than it seems to me. I really don't know haha! I'd already be really really happy if I could get a simple saw wave modulating that volume.
I hope I was clear enough explaining what I want to accomplish. If I left out any useful information do ask!
I hope some of you more experienced people can help me out. thanks in advance!
