In Martha's Flex Friday session, Jim Stafford, retired electrical engineer and member of the North Fulton Amateur Radio League's Education Committee, presented an introductory lesson on Arduinos to PreUpper students Andrew Buchberger, Adriano Hagedorn, Michael Mendoza, and Matthew Carlson. An Arduino is a microcomputer, small in size but amazingly powerful.The first task accomplished by all of the students was to control the rate at which a LED flashed."I did it!" exclaimed several students. "If you can control a LED, you can control a door, a switch, or other things," Jim told the students and made reference to how Martha used an Arduino to make record some measurements of the atmosphere at a model rocketry program this past summer.Next students put together electronic components on a breadboard, a device where circuits can be mocked up to see if they will work before connections are soldered into place. These circuits were connected to the Arduinos and the program on the Arduino now controlled the LED on the breadboard. Students instantly wanted to do more and more complicated things. Alas, we were nearly out of time for this session. "Well, we'll do that in the next class," Jim said. "When is that?" asked the students. "Tomorrow" Jim kidded. "What time?" Even though tomorrow would be Saturday, the students wanted to come in and do more.
