Build an Arduino based thermal scanner

Step 2: Hardware setup - Electronics

First you need to get the hardware all set up. I used an old IDE connector and stripped out the pins for an easy connector, but anything will work fine. My only reason was to make it quickly removal and neat. 

Pictures describe best, but here's a text breakdown:

pin 9/10 are servo Pan/tilt connections
pin 2 is IR clock
pin 12 is IR data

Servo connection:
wire servo 1 white (pwm pos.) wire to pin 9, red to 5V and black to ground
wire servo 2 white wire to pin 10, red to 5V and black to ground

IR module (http://www.metrisinst.com/item_management/assets/files/TN9_UserManual_009.pdf):
wire IR data (pin D on module) to pin 12
wire IR clock (pin C on module) to pin 2
wire IR power (pin V on module) to diode from 3.3V supply
wire IR ground (pin G on module) to ground
(laser pointer versions -- solder a wire from V to the laser pos wire to have that on when measuring)
Remove the battery from the module!

Now you'r electronics are all set up and ready to be placed somewhere.
