Automated Fertilizer Spreader #ArduinoMonday

Excellent project from Courtney Achen up on Hackster.io.

One day I fertilizing my yard and thinking about what my next project should be. After about an hour of trying to get the rate set correctly on the fertilizer spreader, and uncomfortably reaching behind me to turn it on and off manually I decided there had to be an easier way.

So I decided to automate the process with an Arduino and a stepper motor. Check out the video below. Now all I have to do is press a button to turn it on and off, and use a knob to adjust the rate.

Panel Mount 10K potentiometer (Breadboard Friendly) – 10K Linear: This potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2″ apart with pin-points, so you can plug it into a breadboard or perfboard. Once you’re done prototyping, you can drill a hole into your project box and mount the potentiometer that way. (Read more)
