I wanted to challenge my nephews and nieces for Christmas. While searching the Internet, I stumbled on Clickspring machined impossible dovetail puzzle on Youtube. It is an amazing job and I decided to design one myself. Taking it as an inspiration, I modified it a little and added some extras to make it more challenging.
After a few months, it was about time to release a new OpenRC tractor tool. In this case it’s a spring loaded cultivator. It levels the surface of soil to prepare a perfect seed-bed. As it is spring loaded, it’s suitable for use in stone and root obstructed soil. If one tine strikes a hidden object, the others will continue working at the correct depth.
In this activity you’ll program your first Arduino code.
This code turns a LED on for a second, then off for one second, repeatedly. You can find this code under Arduino IDE -> File ->Examples -> Basics ->Blink
You don’t need any extra components as it uses a LED connected to pin13 that most Arduino boards have.
