Cali’s Portfolio

Electronics  By Cali, 11

In this class, we learned how to program Arduinos, a micro-controller created by a couple MIT alumni.  We used variables such as “int”, “float”, and “long”, and functions such as “pinMode”, “digitalWrite”, “digitalRead”, “analogRead”, and “analogWrite” to program different projects.  Our circuits were made up of resistors, LEDs (lights emitting diode), buttons, speakers, 7-segment displays, and some other pieces.  We also learned about many types of communication, such as serial communication, I2C communication (which uses only 2 wires to communicate with 1008 different computers!), and many others.  One of the fun activities was making two projects- an ultrasound range finder and a sound reactive lights and speaker coordination.  I liked the latter best!  All together, I had a fun time learning the basics of electronics and programming with an Arduino.
