How to get a arduino to use 3push buttons as inputs, and output a different signal on a speaker
I am new to the whole arduino using world. I have a project that uses 3push buttons, a breadboard, arduino, lcd display, and speaker.
The goal is to write program to play a certain freq. signal through the speaker, (each pushbutton has it's own frequency for the signal) when each of the buttons is pushed, and also display each signal on the LCD display while doing it.
