Instructions | Room Temperature Cup Holder

1

Attach Thermal Adhesive to Heat/Coldsink
2

Attach Peltier to Heatsink via Thermal Adhesive

Remove the blue protective plastic from the thermal adhesive. Place the Peltier module on the thermal tape numbers down
3

Attach Thermal Adhesive to Peltier and Attach Cup Holder

Apply 2 pieces of adhesive tape to the Peltier heater/cooler, remove the blue plastic from the adhesive and attach the cup holder. Make sure you get it centered the first time as the adhesive is very strong and the Peltier units are fairly fragile!
4

Solder 2 Wires on Both Red and Black Wires of Peltier

Split the red and black wires into 2. Don't forget the shrink wrap
5

Attach Peltier Wires to H-Bridge

Attach both black and both red wires to the H-Bridge as shown. The reason for splitting the wires is to take advantage of both sides of the dual H-Bridge for maximum current. The Peltier can pull ~4A at its peak.
6

Connect the +12V Supply Power and Ground Wires to The H-Bridge

See the Orange and Black Wires in blue terminal block in the photo above and Schematic
7

Create 3 Single Male to Dual Female

Cut solder and shrink wrap 3x Single Male to Dual Female jumper wires like shown in picture
8

Connect the Wires Created in Previous Step to the H-Bridge and Arduino

Arduino UNO
H-Bridge
Pin 9
ENA, ENB
Pin 10
IN2, IN3
PIN 11
IN1, IN4
