Arduino Keywords

setup()
This is the function that tells the arduino how to set its self up.

loop()
This is what the arduino is to do while it is running.

analogRead(pinnumber)
read an analog value (0 -> 1023) from the pinnumber given

Serial.print()
print ASCII to the serial

Serial.println()
Print ASCII to the serial port but also add a line break after

pinMode(pinnumber, mode)
pinnumber = the number of the digital pin on the arduino board.
mode = Can be ether 'INPUT' for receving data or 'OUTPUT' for sending data.

digitalRead(pinnumber)
pinnumber = the number of the digital pin on the arduino board.

Task 11 & 12 - Blink2 (Controlling 2 blinking LEDs)

/*

Blink2

Turns on a LED on for half a second, then off for half a second, repeatedly. It also does the same to an off-board LED connected to pin 12 so that when one LED is on the other is off.

The circuit:

* LED connected from digital pin 13 to ground via resistor.

* second LED connected from digital pin 12 to ground via resistor. I used 330 ohms.

* Note: On most Arduino boards, there is already an LED on the board

connected to pin 13.

LED Mono Color Matrix Completed

This is my home made board for my LED Matrix, its a 5x5 grid of Green LEDs, now i can move on and start the programming.

LED Assignment

My LED assignment is a martix, using a 5x5 grid of Green LEDs i will make a simple pattern turning LEDs on and off using the arduino
