Board description of Arduino
Board description varies with Arduino models, basic model Arduino UNO contains 6 analog pins and 14 digital pins. Along with power supply pins. The maximum input supply is 12V. operation voltage at 5V.
General Input /Output Devices for Arduino
- Analog pin starts from A0 to A5
- A4-SCL
- A5-SDA
- DIGITAL pin starts from 0 to 13 in which 0-RX, 1-tx, 13-SCK, 12-MISO, 11-MOSI, 10-SS.
- PIN number 3,5,6,9,10,11 act as PWM (pulse width modulation) pins
Software Arduino IDE
Arduino ide is a graphical user interface used for Arduino commanding. Here we use embedded c for commanding.
