This hands-on class introduces the core building blocks of interactive electronics: inputs, outputs, and control. Participants will learn how microcontrollers read information from a sensor and translate that information into physical motion using motors.
Electrics & Microcontrollers: Inputs + Outputs
Next Occurrence: February 14, 2026
This class emphasizes practical experimentation and real-world applications. Students will work with a simple sensor input and control multiple types of outputs including DC motors, servo motors, and stepper motors using a microcontroller.
By the end of the session, participants will understand how interactive systems are structured and leave with the confidence to build projects like kinetic sculptures, automated mechanisms, robotics, and responsive installations.
What You’ll Learn
- How microcontrollers read and interpret sensor data
- The difference between analog and digital inputs
- How to control motion using DC motors, servos, and stepper motors
Tools & Equipment Used
- Microcontroller (Arduino-compatible)
- Breadboard and basic electronic components
- Sensor input (potentiometer or distance sensor)
- DC motor
- Servo motor
