• A phase-shift oscillator converts actual temperature into frequency
• Arduino measures frequency and computes the corresponding temperature
• A solid-state H bridge controls the current (amplitude and direction) flowing through a TEC
• The desired temperature is set via a infra-red remote
• The observed temperature shows on the LCD screen
