Wrap one end of resistor to one leg of the thermistor, solder and trim leads.
the thermistor/resistor module does not need to be soldered into the 3-pin clip. When inserted into the clip end of the 3-pin clip, the
bare thermistor leg should connect to the BLACK wire, the resistor leg should connect to the RED wire and the thermistor leg that has the resistor soldered should connect to the DATA wire (the DATA wire could be YELLOW, WHITE or even BLUE)

Attach the header pins to the arduino on the front right side of the arduino.  These pins will be used with the FTDI cable to program the arduino.

Bend pins out flat then straight again so the footprint is wide enough to fit in the Arduino holes. you will also need to bend the #9 pin
so it fits in the GND hole on the TOP FRONT of the Arduino.

Align the 7 segment display so the pins fit the Arduino holes and confirm that the #9 pin on the 7 segment display fits in the GND hole
on the FRONT TOP of the Arduino.

Connect your computer to the Arduino with your FTDI connection and upload the thermistor program (source program included here made up of parts taken from samples online)

Confirm the pins on the 7 segment display fit in the holes on the BOTTOM FRONT of the Arduino.
