Open Source Software

Power of Community

Collection of Best Practice

• Stop trying reinvent the wheels.
• Fix them instead.

Open source projects I love most

What makes a great open source project

• User & Hacker friendly
• Well documented source code
• Clear designed interfaces
• Keep in touch with community

Why Open Hardware?

• Bring ideas off your chair
• More fun with REAL objects
• Make your dream come true, make life better

Great Open Hardware

Raspberry Pi

Credit-card Sized Computer

Arduino

Single-board Microprocessor with Great Toolsets

Why Arduino is great?

• Cheap, easy to get
• Expandable modules
• Excellent programming interfaces
• Open source community

C Code

void main(void) {
          WDTCTL = WDTPW + WDTHOLD; // Password, and stop the timer
          P1DIR = 0x40;             // P1 Direction is OUTPUT
          P1OUT = 0;                // P1 OUTPUT low
          BCSCTL3 |= LFXT1S_2;      // VLO
          IFG1 &= ~OFIFG;           // Use DCO if clock fault
          _bis_SR_register(SCG1 + SCG0);  //stop DCO to wait for VLO
          BCSCTL2 |= SELM_3 + DIVM_3;
          while(1) {
            P1OUT = 0x40;
            _delay_cycles(100);
            P1OUT = 0;
            _delay_cycles(5000);
          }
        }

Arduino Code

void setup() {                
          pinMode(RED_LED, OUTPUT);     
        }

        void loop() {
          digitalWrite(RED_LED, HIGH);   // turn the LED on 
          delay(1000);               // wait for a second
          digitalWrite(RED_LED, LOW);    // turn the LED off
          delay(1000);               // wait for a second
        }

It's Easy!

Arduino is the brain
