Learn how circuits and signals work in a robotic system
Electrical Foundations focuses on the foundational concepts around basic electricity and how circuits work. In this course, students learn how to use multimeters to measure various parts of a circuit. Students learn how to control signals using a microcontroller, how to utilize binary sensors like Limit Switches, and analog sensors like an Ultrasonic Sensor. The culminating project is an e-panel consisting of all of the components found in a typical robotic system. SMART is an ARM Endorsed program
