TL:DR - Real Time Digital signal processing: UART Controlled Arduino UNO signal generator

April 13 2021, Roy Ben Avraham;Mk;Ge

In this project, the goal is to write a skech for Arduino Uno which will enable to produce (by using 4 bits R2R DAC) the following Analog signals:

1) Sin wave

2) Sawtooth wave

3) Dumped cosine wave

Show a menu for the user (by pressing '?') - User interface

In the user interface the user will be able to change certain values: (and choose the signals 1-3)

A- Amplitude in Volts in the range [0-5] [V] F- Signal frequency, F=1/T (T- period in seconds, created signal must contain 64 counts per period)

B- Amplitude of the Pseudo-random flat noise (in the range [0-5] [V]) C- Number of positive bumps per period T with amplitude 1V, C is in the range [0-5][V]

In this project I will use TinkerCAD simulation to demonstrate some of the functions of this project.
