Overview
The 7‐Segments shield is developed for Arduino compatible boards, to provide a user‐friendly
interface that allows users to go through the menu, make selections etc.
It consists of a 4 Digit 7‐Segments (Single pin Serial Interface 9600bps), Analog Pushbuttons
Switch 5 that form a joystick‐style keypad, LED 3 bit User define, DS1307 Real Time Clock, 24L128
EEPROM, TMP75 Digital Temperature sensor all onboard.
For test and develop basic microcontroller in peripheral device interfaces.

Signal Interface
The 7‐Segments RX serial RS232 TTL level compatible interfaces. RS232 TTL control interfaces
(9600, n, 8, 1), for software serial interfaces or hardware serial interfaces. A different set of IO pins is
used. See Schematic.
The power pins are as follows:
• 5V. the 5V supply.
• GND. Ground pins.
