The HERO is a derivative of “Arduino UNO R3 Reference design” we just changed up a few things to make it our own. If you’re curious about what goes into our HERO board we published the open-source hardware files on our GitHub.
I have found a way to include arduino into my science class without being a coding / robotics class.
In this case, I use the DHT11 sensor as a tool to measure climate conditions and help students track the weather for a given amount of time.
This code measures temperature, humidity and heat index.
