Learn Arduino Using Maker UNO - Lesson 6

The biggest problem I faced when I wanted to learn Arduino was there are too many documents, learning guides, tutorials flooding around the internet and I had no idea which one to refer to.

Most of the learning guides that claim they were crafted for the beginners are just too surface while most of the time they only show you the schematics, give you the sample codes and tell you what to expect but they do not explain how it works. It is very frustrating for people like me who do not have C-programming background. Although I can achieve the expected results by following the schematic and codes given but I am pretty sure I can’t create my own project after I completed the lessons.

Another problem that I observed was most of the learning guides are created by the techies where things are assumed to be understood.

There is nothing special with the projects that I covered in this learning guide, I just added some notes and reminders on things that I did not understand. I try to simplify the technical part and I hope that at least the beginners benefit from this and enjoy learning with Arduino.

This beginner guide covers 7 lessons. Each lesson comes with several projects and one open-ended challenge.

Lesson 0 - Setting Up The Hardware & Software

Lesson 1 - Digital Output

Lesson 2 - Digital Input

Lesson 3 - Analog Output

Lesson 4 - Melody Tone

Lesson 5 - Analog Input

Lesson 6 - DC Motor

Lesson 7 - Ultrasonic Sensor

Lesson 6 > Project 14: Control A DC Motor

Step 1. Get ready these components

Step 2. Construct the circuit as shown below.

Step 3: Write these codes then upload to your board.

Step 4. Hold the DC motor then press the on-board pushbutton switch.

Step 5. Check your result.

Lesson 6 > Project 15: Controlling Motor Speed Using A Pushbutton

Step 1. Write these codes then upload to your board.

Step 2. Check your result.

Q: The motor will run at a constant speed when you press and hold the pushbutton. It will stop when you release the button. When you press the pushbutton for the second time, the motor’s speed will change.
