Temperature controller with PID and H-Bridge

In this video I show how I control the temperature of the heatsink (the upper heatsink). This is just a prototype.

The peltier modul is between two heatsinks. The bottom is in the water for cooling. For reading the temperature I use BMP180 temperature sensor, which is in the upper heatsink (this is the feedback). The modules is controlled by atmega328 with PID regulator. The output of the PID regualtor is PWM signal connected to H-bridge (I can heat if it is needed).
