In these lessons, you will learn the basic concepts of circuits, coding, and how they can be applied to sensors. The lessons focus around using the Arduino Uno microcontroller in order to read inputs from sensors and manipulate outputs with lights.
Through these lessons, you will learn:
- How to wire circuits containing electrical components such as LED’s, resistors, pushbuttons, and potentiometers
- How to create voltage dividers and calculate their output voltages
- How to use flex and pressure sensors
- How to read inputs using the Arduino and create an output effect using code
The first three units will walk you through how to create basic circuits using LED’s, pushbuttons, and potentiometers. Each unit will first demonstrate how power travels through the circuit and how each component affects the circuit by learning hardware. The unit will then walk you through a similar circuit set up that implements Arduino code using Arduino software to show how the circuit can be manipulated using code.
