In this article you will learn how to build an optical theremin using a 555 Timer IC. You will learn the functions of the pins on the 555 chip that are used in this build. You will learn that when the ...
Many microcontrollers or PICs will have uncommitted digital-to-analog converter (DAC) outputs that can be used to generate sine waves. But these are generally low resolution (8 to 10 bits), yielding a ...
