2AN AUTOMATED AGITATOR FOR PCB ETCHING

image

This project uses the Arduino microcontroller to sense change in a motor’s current drain (the rate at which the motor uses electricity) and then reverse the direction of the motor. There are numerous applications for the measurement and use of current drain, and this project provides an example method that can prove useful in the development of future electronics projects.

Making Your Own PCBs” on page 13 illustrates different ways to design and make circuit boards at home for a very modest cost using readily available and environmentally safe household products. Part of this process includes etching the ...
