Nearly every project needs a user interface. The ATS-1 Terminal Shield is the quick way to add one to your Arduino project without using up all your I/O lines. It includes a 16x2 alphanumeric LCD display, a master reset switch, a programmable LED, 6 user navigation buttons and a buzzer. This shield uses only 2 of the Arduino's digital I/O lines, saving the rest for your application.

The ATS-1 shield works with the Arduino Uno, Duemilanove and other compatible CPU modules. It only needs the D0 and D1 serial lines for communication. Send text to the display and control the LED and buzzer with the standard Serial.print() functions. User switch presses send the switch number to the Arduino. Use the Serial.read() function to capture them.

The ATS-1 can also use software serial libraries (available on the Arduino site) to use other digital I/O lines for communication. Wire jumpers let you select which pins you want to use. Solder pads also let you wire the ATS-1 to your non-Arduino based microcontroller project.

The ATS-1 comes assembled and tested. LCD style may vary slightly from picture.
