Part 1: Setting up the Arduino
1. Connect to your wireless network
2. Install Arduino software from www.arduino.cc
3. Check if Windows automatically installs CP2112 USB-UART driver. Else, download driver from:
https://tinyurl.com/CP2112driver
NOTE for MAC users: Go to the Appendix at the back for help on how to install driver.
4. Connect Arduino board via USB cable to PC
5. Add Additional Board Manager URLs: FILE -> Preferences

Part 2: Running the Blink Program
10. Open the File -> Examples -> Basics -> Blink
11. Investigate the program – which function blocks do what? Check that the LED is blinking properly.
Hint: Compile and Upload are in the top left corner of the IDE:
Part 3: Morse code
12. Alter the blink program to Morse SOS. Save the Blink program with name:
”Morse_SOS_yourname”
13. A few tips:
•All timings are defined as multiples of one dot length
•A dash is three times the length of a dot
•Each dot or dash has a short gap of silence after it (usually 1 dot length)
•Letters in a word have a slightly longer gap of silence between them (usually 3 dot lengths)
•Words have an even longer gap of silence between them (usually 7 dot lengths)
