SparkFun Item #: SF-BOB-11733 -

    The SN74HC165N is a neat little IC that will take an input of up to 8 parallel lines and produce a single, serial output. It’s a great way to increase the number of inputs on a microcontroller. This breakout makes it easy to prototype using the 74HC165 by breaking out all of the pins you need to standard 0.1" spaced headers. We’ve also lined up the data and power pins so that you can easily make chains of them and expand the number of outputs under your control! This chip works with a voltage...

    Seeed Studio Item #: SS-COM22639P -

      Description The Relay Grove is a digital normally open switch that controls a relay capable of switching much higher voltages and currents than your normal Arduino boards. When set to HIGH, the LED will light up and the relay will close allowing current to flow. The peak voltage capability is 250V at 10 amps. Please exercise great care when working with mains voltages— if in doubt contact a professional such as a licensed electrician for help. Document How to use ...

        Time to step up the voltage with this Arduino Relay Board. The Arduino platform is a great way to control lights, buzzers, displays and more - but what if you have a device that doesn't run on the Arduino's native 5 volts? One simple way to do it is to use the RobotGeek Relay. This little relay board will use a signal from a 5v microcontroller to make a mechanical connection. This connection is physically seprated from the arduino, meaning you can connect devices that have different voltages...
