First School Project update: Audio Amp schematic
My first plan for an audio amp circuit was a bit naive, i didn't think i'd need an increase in power for some reason, so i just didn't have any transistors,
the whole thing was just boosting the amplitude of the signal.
This circuit is pretty much just a modified version of a circuit i had to do for my analog circuits class.
the main difference is the amp's gain changed to maximize it's +12/-12V power supply on my arduino's lowered signal (a resistor divider lowers the signal from 5V to 500mV before going to the amp)
Made with LibrePCB
My School project: Arduino Synth
I really enjoyed using arduino boards during my classes, and i really wanted to get familiar with some analog synth concepts
before possibly making my own during this summer.
This "Arduino Synth" would work by letting the arduino play pre-made melodies as square waves, with an lcd screen showing which ones are playing.
The electronic meat of this project would be found in an active low pass filter and an audio amplifying circuit for 2 speakers on both ends.
