Arduino Project Board

The complete Arduino Project Board Kit includes:

(x1) Arduino Project Board PCB (or you can make your own with ProjectBoard.pcb)
(x1) Bootloaded ATMEGA328 chip
(x1) 28-pin socket
(x1) 16 mhz crystal
(x2) 22pF capacitors
(x1) 0.1uF, 25V capacitor
(x1) 10uF – 47uF, 25V capacitor
(x1) 1K, 1/4 watt resistor
(x1) tactile switch
(x1) 7805 regulator
(x1) 9V battery clip

Solder the 1K resistor to R1 on the board.

Don’t forget to clip away the excess leads from the back side of the board.

Line up the switch with SW1. Then press it down until it “pops” in and becomes flush with the board.

Solder it in place.

Put the socket atop the spot for the Arduino. Make certain that the notch cut into the end of the socket is located next to the 1K resistor.

Solder all 28 pins in place.

Solder the electrolytic capacitor in the spot labeled C3.

Don’t forget to make sure the “-” stripe on the capacitor is opposite from the + label on the board.

Add the LM7805 voltage regulator to the board in the spot labeled 7805.

The metal plate on the back of the regulator should be on the side opposite of the capacitors.

I added a test LED to the board of this example to demonstrate it is working.

I suggest that you don’t do this if you don’t have to and only add the parts you need for your project.

Anyhow… in this example the LED is connected to Pin 12 (Digital Pin 6) and then to ground through a 220 ohm resistor.

Program your chip and transfer it to the board.

Here is the blink code for the LED example shown in Step 11:

/*
  Standard Blink example set to Digital Pin 6 (ATMEGA328 pin 12)
  There is one long blink on startup before going into main routine

  This example code is in the public domain.
 */

void setup() {                
  // initialize the digital pin as an output.
  // Pin 6 has an LED connected on most Arduino boards:
  pinMode(6, OUTPUT);   

  digitalWrite(6, LOW);    // startup routine for testing rest button
  delay(1000);             // LED turns on for 5 seconds and waits for 3
  digitalWrite(6, HIGH);   
  delay(5000);              
  digitalWrite(6, LOW);    
  delay(3000);              
}  

void loop() {
  digitalWrite(6, HIGH);   // set the LED on
  delay(1000);              // wait for a second
  digitalWrite(6, LOW);    // set the LED off
  delay(1000);              // wait for a second
}
