The document discusses the Arduino ecosystem. It describes the components that were needed in early microcontroller development like an MCU, clock source, programmer, voltage converter, breadboard and development tools. It then outlines what is included with an Arduino board like the Atmega chip, USB connectivity, voltage regulator, headers, LEDs and buttons. It also mentions Arduino libraries and the IDE. The document goes on to discuss variants like the Pro Mini and wireless boards. It describes shields that add functionality and lists examples. It closes by showing sample Arduino code and discussing issues with GSM modules.

- 1. Arduino ecosystem Steve Perkson (Teadusmosaiik)
- 2. The good/bad old days
- 3. The good/bad old days ● ● ● ● ● ● MCU of some kind Some clock source usually crystal Chip programmer. Serial level converter 5V or 3.3V to 12V Breadboard Development toolchain
- 4. Arduino
- 5. Arduino - what do you get? ● ● ● ● ● ● ● Atmega 168/328/644p/1284 Some sort of serial to USB capability 5V voltage stabilizer easy to connect headers 2 leds and 1 switch somewhat working development library IDE
- 6. *duinos
- 7. pro mini
- 8. wireless?
- 9. Need something thin and flexible
- 10. Shields ● ● ● ● Sort of standard pinout Sort of standard voltage range Quite a lot of different goodies Even more problems
- 11. Shields ● ● ● ● ● ● ● Bluetooth GSM Xbee Ethernet Wifi CNC, 3d printer, laser cutter Quadcopter
- 12. Ethernet
- 13. and more ;)
- 14. How does the code look like? void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); }
- 15. code part 2 // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); delay(1000); } // turn the LED off by making the voltage LOW // wait for a second
- 16. Code was supposed to be C++, where are the includes? ● Arduino IDE hides all the complexity. ● IF it breaks, it breaks and you get to keep all the pieces ● It breaks.
- 17. GSM modules ● ● ● ● RTFM and then read it again. Then find an older/newer manual and read it. Also compare to previous HW version. Never ask your Telco for any QOS class
