IO Expansion shield is one of the market favourites. Fast robotics prototyping made affordable and simple thanks to this design. Soldering and wiring often becomes a problem when a bridged connection happens and components break. Increasing time and cost for projects. Often, without this solution and a soldering station, wire cripping tools or soldering station, robot prototyping or electronics DIY becomes a very long term project.
The DFRobot Expansion shield introduced to the market the famous color code for sensors and actuators input and output. The 3 pin format for Signal, Voltage and Ground is extremely useful, specially if used altogether with our increasingly large range of modules, sensors and devices that just fit .
Alternatively, the board includes power input for salvaged power supplies or laboratory power supplies. Very common Xbee socket for multipurpose wireless connectivity such as RF, wireless, bluetooth.
The new version includes a voltage hardware setting through a jumper to allow compatibility with a bigger range of components at 3.3v like Raspberry pi, Due and others.
It also includes a Servo external power, with a protective diode. This way you can enable a large range of servos from your Arduino.
Latest version features a convenient switch that lets you program your ATmega328 boards like UNO, while you have another Serial device connected like a Xbee. Switch it, program it and get it back up and running with another switch. You don"t need to disassemble your hardware or wiring.
A LED on top board and a reset button is in order to make it just a natural extension to Arduino boards. The LED is connected to pin 13.

KnowFlow is the name of this water quality monitoring device, based on Arduino Uno. It can automatically monitor 5 parameters of water: pH, Temperature, Dissolved Oxygen, Electronic Conductivity, ORP.
Project 7. How to Make a Santa Alarm Using the new RGB color sensor available at DFRobot, I rigged up a simple proximity alarm. I can use this to warn me if someone is in a close range of my Christmas tree putting presents under there. The hardware of this project is pretty simple and suitable for beginners. 1 x Bluno Microcontroller v2.0 (SKU: DFR0267) 1 x Gesture Sensor 1 x I/O Expansion Shield v7.1 (SKU: DFR0265) (the extra I/Orsquo;s are very useful and prevent messy wiring!) 1 x Digital Buzzer Module (SKU: DFR0032) 1 x 220R Resistor (any will do) 1 x Red LED 1 x Breadboard (for prototyping and checking the circuit ndash; any will do.) Jumper Wires for connections
When finishing reading this tutorial, you will find those very simple devices, principles and technologies can help you build very interesting equipment.
