Arduino Ethernet Shield Real Time Clock which can be controlled directly

which can be controlled directly by a wide range of microcontrollers such as Arduino

Supply Voltage Range: 2V to 6V

the select inputsselect one of the four binary inputs and routes it to the multiplexer output (nY)

Gauge - 22 AWG

It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings

Arduino Ethernet Shield Real Time Clock which can be controlled directlyIntroduction : Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the W5100 ethernet chip . The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet Library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire wrap headers which extend through
