Introducing the Arduino
- 1. Introducing the Arduino Boadu A. Charles Jnr
- 2. Definition …an open-source electronics platform based on easy-to-use hardware and software.
- 3. • Eaaaaasy to use • Inexpensive • Cross-platform • Simple, clear programming environment • Open source and extensible software • Open source and extensible hardware Why Arduino?
- 6. How to Use the Arduino • Write code in Arduino IDE. • Connect Arduino to PC using USB cable. • Click button on IDE to compile program. • Click button on IDE to load program unto microcontroller. • Voila!
- 7. …any device that accepts input, performs some computations or processing of the input and produces an output. Technically, that makes an Arduino a computer. Compared to a Computer
- 9. Input
- 10. Input Pins 20 Input Pins 14 Digital Input Pins 0-13 6 Analog Input Pins A0-A5
- 11. Input Pins - Example
- 12. Processing
- 14. Processing Atmega328P Specs Program Memory Size 32KB (16K x 16) Program Memory Type FLASH FLASH Memory 32 K EEPROM Size 1KB RAM Size 2KB Voltage - Supply (Vcc/Vdd) 1.8 V ~ 5.5 V
- 15. Output
- 16. Output Pins 14 Output Pins 8 0/1 Pins 0,1,2,4,7,8,12,13 6 PWM Pins 3,5,6,9,10,11
- 17. Output Pins - Example
- 18. The Arduino and Power
- 19. Power Ports Male Power Jack A-B USB Socket
- 20. Power Supply 9V Adapter Standard A-B USB Cable Battery Pack with Female Jack
- 23. Software IDE
- 25. Code Structure 1 void setup() { 2 3 } 4 5 void loop() { 6 7 }
- 26. Sample Program 1 1 void setup() { 2 pinMode(13, OUTPUT); 3 } 4 5 void loop() { 6 digitalWrite(13, HIGH); 7 delay(1000); 8 9 digitalWrite(13, LOW); 10 delay(1000); 11 }
- 27. Sample Program 2 1 void setup() { 2 pinMode(11, OUTPUT); 3 } 4 5 void loop() { 6 for (int i=0; i<255; i++) { 7 analogWrite(11, i); 8 delay(500); 9 } 10 }
- 28. Programming Workflow 2. Verify/compile code 3. Upload code unto microcontroller Converts wiring language to bytes of instructions in one Intel hex file. Loads hex file unto microcontroller 1. Write code Keep your eye on the logs
