PURPOSE/GOAL• Design an applied physics course (PHYS 306) centered around use of the

Arduino microcontroller. • Pre-requisites: Physics 105 and 106 (circuits and electronics). • 3rd semester, 2 days a week, 2 hours each day. • Each student will have an Arduino UNO Super Starter Kit.• Several smaller projects using components/sensors.• One big final project – Solar Panel Project!

USING AN ARDUINO• Choose the components/sensors you will need and determine how will

you connect them. (Circuit Design)• Wire them to the Arduino via breadboard. (The Build)• Write your program to control the components in, and read the data.
