Question: What’s got four 7-segment displays (and driver), a temperature sensor, a PWM RGB LED, and plugs into an Arduino? Why it’s the Arduino 7-Segment Shield! This is a 7-segment shield for Arduino NG/Dicimila/Duemilanove and many Freeduino boards. It has tons of cool features! Fully assembled and tested! NOTE: Does not include the Arduino board.

Features:

• I2C 4 digits 7-segment driver
• I2C temperature sensor
• I2C EEPROM
• PWM RGB LED
• Blue PWR LED
• Reset button
• All pins breakout

With the ability to read temperature data and display it on its four digits, this could be just the shield you need to push your kegerator project over the top.
