ArrBot: Assembling the Arduinos

Assemble The Arduino Micro

Solder the male pins down each long row.

• Put the pins in the breadboard.
• Long end of pins go into the breadboard.
• Line up the Arduino Micro so that it sits on the pins.
• CPU goes on top.

Assemble The Arduino Mini

Solder the male pins down each row.  Same as for the Micro.

Solder the end pins.

• Those are the 90 degree pins.
• They go into the 6 through holes on the short end.
• Use the helping hands.
• Flip the board over, the CPU should be on the bottom.
• The short end of the 90 degree pins should come through the holes.

Test the Arduino Micro

• Put the Micro on a breadboard.
• Run a wire from GND to the row next to output pin 9.
• Put an LED on pin 9 and the GND wire.  Don't worry about a resistor.
• In the Arduino IDE, be sure to select Tools / Board / Sparkfun Pro Micro 5V/16MHz.
• Load Files / Examples / Basics / Blink
• Set  led = 9 in the source code.
• Set  delay(100) in the source code.
• Download the program.
• The LED should blink quickly.  If it doesn't, make sure your LED polarity isn't backwards.
• Set led = ??? in the source code to use the built-in LED.

Test the Arduino Mini

• This one has a built-in LED, so it's a bit easier.
• In the Arduino IDE, be sure to select Tools / Board / Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATMega328.
• Note that the black wire on the FTDI connector connects to GND.
• Load Blink as above.
• Keep led = 13.  Change delay(100)
• Download the program.
• The LED should blink quickly.
