I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.
In this Simple Tutorial we will learn how to make a PWM using Arduino and observe the Signal on the Oscilloscope.
Things you should know while amplifying a 10mv DC signal to 100mv or 1volt and different approaches to the configuration.
A simple TTL modulated diode laser.
A small, cheap, low-powered FM Radio Transmitter to create your own Radio Station at home.
Do you have a bunch of servos? What about a couple of big ol' motors, or even a ton of LEDs? You will probably need a capacitor pack.
In this tutorial we will learn how to use MCP4725 12Bit Digital to Analog Converter with Arduino to generate Square, Sine & Triangle waves.
