Microcontrollers are perfect tools for making things move, and controlling other things like home automation, wheels, legs, tracks, terminator robots and more!

How to enter the Microcontroller Contest?

Create a new photo, video, or step by step Instructable which incorporates a microcontroller and share your code. It can be as simple as scaring your cat with a buzzer, or a high tech rover for Mars exploration. A video showing what it does is a big plus!

Bonus: everyone who enters will receive a discount code for 50% off a DFRobotShop Rover from RobotShop!

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Jun 8, 2011 and Jul 4, 2011 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Microcontroller Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
