Arduino, the family of open-source single-board microcontrollers, can power a variety of complex projects, from robots to wearable tech. Arduino enables programmers to experiment with hardware and build interactive, digital projects connected to lights, sensors, and motors. This course introduces you to the Arduino microcontroller, showing how to interface with three common components: an LCD screen, a seven-segment LED, and a keypad.

Arduino helps engineers and DIY enthusiasts build functional, interactive prototypes and electronics projects. Integrating analog devices allows you to take your Arduino projects to the next level, bridging the digital and physical worlds. With analog components, you can collect data from sensors, make motors run, and display information to users. This course teaches you the basics you need to get started.

Pulse width modulation (PWM) is an essential skill for connecting Arduino microcontrollers to motors or lights, providing a way to approximate analog voltage levels with digital signals. Using PWM, you can control and program the brightness of lights and the speed of motors—bringing your projects to life. 

This technology is relatively easy to pick up, even for those without an electronics background.
