PJ019: 1st Experience with Arduino

Step 1: Create a "Sketch (program file)" with example codes

In Arduino toolchains, "Sketch" refers to the program files (with .ino extension) that contains the C/C++ codes. I.e. "Sketch" is the .ino file.

Create a new "Sketch", input the codes as example here.

Be careful with the writing and punctuation, formats, it's not necessary to understand the exact "what/how" for now, let's focus on the "work flow" steps in this task.

Check what target board you have got, update the pin ID accordingly

• 13 for Arduino UNO R3

• 25 for Arduino UNO WiFi Rev2

Step 2: Verify/Compile the "Sketch (program)"

Click the "tick icon" for "Verify/Compile"

Step 3: Upload program to target board

Step 3: Upload program to target board

This challenge uses combined digital input/output and external wiring.

• pin 10 for external button

• pin 11 for external LED

• also uses built-in LED, mapped to pin 13 for UNO R3, pin 25 for UNO WiFi Rev2

Create a fun logic in program, here is an example, it uses the button to alternate the on/off between the 2 LEDs.

Below are some examples of the hardware wiring, you can use either type of button provided by the tutor, use breadboard or even just direct connection using alligator clips.
