Arduino Night (25 Jan, 7-10PM)
We will cover how to use an operational amplifier to both amplify a signal, and add DC offset. Then we will go over how to use a R2R ladder to convert digital to analog. Finally we will combine both to have the Arduino sample audio using it’s A2D converter, and then spit it right back…
