Arduino Microcontrollers

There are multiple flavors of Arduino:

• Uno – 16 Mhz ATmega328 with 14 Digital I/O pins
• Due – 84 Mhz AT91SAM3X8e with 54 Digital I/O pins
• Mega – 16 Mhz ATmega2560 with 54 Digital I/O pins
• Leonardo – 16 Mhz ATmega32u4 with 20 Digital I/O pins

Arduino Lesson

How to program 4 Arduinos in 4 minutes.

1. Turn on the HP Ultrabook and login with the Password Fox.Build.
2. Open Arduino.
3. Take the UNO on the left off the wall, and plug it it in to the computer with the USB ‘B’ cable.
4. Open File->Examples->Basics->Blink
5. Then select the board
6. Tools-> Board->Arduino/Genuino UNO
7. Check Tools/ Port and choose what ever port is showing.
8. Click on the upload round button under the edit menu item. It is an arrow.
9. Once it uploads the Uno should start flashing.
10. Change the number in the program next to delay to what ever you want.
11. This is the number of milliseconds the program waits while the LED is on or off.
12. Click upload again and confirm the speed the LED flashes changes.
13. Congratulations, you just completed an Arduino “Hello World”.
14. Now lets do the other 3 boards.
15. Return the UNO and take the little Nano next to it.
16. Swap out the ‘B”‘ cable for the Mini cable on the left.
17. Change the board with Tools->Board to Nano.
18. Check the port again to make sure a port is available.
19. Tools/ Port and choose whatever is there.
20. Upload the program and change the delay again as you like.
21. Wash and repeat for the ESP8266.
22. Choose Tools/Boards -> Wemos D1 R2 and Mini (Way at the bottom.)
23. Check the port and upload.

Wash and repeat for the Mega.

You have done it!
