Learning Arduino: Interfacing with Hardware

Description

In this course, you will learn :

• Programmers can use Arduino to experiment with hardware and create interactive, digital projects that are linked to lights, sensors, and motors. This training course introduces you to the Arduino microcontroller and demonstrates how to connect it to three common components: an LCD screen, a seven-segment LED, and a keypad.
• Zahraa Khalil demonstrates how to wire and programme the interfaces and perform basic tasks such as displaying randomised numbers, looping through an LED pattern, and accepting keypad input.
• The course includes zoomed-in, hands-on demonstrations of how to finish the physical wiring as well as tutorials that walk you through high-level Arduino concepts and practical coding techniques.
• Follow along to discover how to make your own electronics using this popular maker technology platform.
