The “5 minute” agitator

This is why Arduino is awesome: 5 minutes, some junk, instant PCB etching agitator!

Confused about whats going on here? Basically Matt Stultz, my fellow cohort at Hack Pittsburgh, was etching a custom PCB breakout board and got tired of agitating the acid bath by hand. Since I’m such a nice guy, I quickly whipped up a little agitator system using a surplus servo unit and an Arduino microcontroller to control it.

The sketch looks something like this:

#include <Servo.h>
 
Servo myservo;
 
void setup() {
  myservo.attach(9);
}
 
void loop() {
  myservo.write(100);
  delay(1000);
  myservo.write(120);
  delay(1000);
}
