INTRODUCTION
Here is the simplest sound making module that you can use High/Low to drive it. Just change the frequency it buzz, you can hear
different sound. It is widely used on your daily application, like PC, refrigerator,phones and so on. And you also can create many
interesting interactive project with this small but useful module.
To ease the difficult of using this sensor, a Gravity Interface is adapted to allow plug&play. The IO expansion shield is the best
match for this sound senor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry
Pi, intel edison, joule and curie.
FEATURES
Wide voltage range from 3.3V to 5V
Standard assembling structure (two 3mm holes with multiple of 5cm as interval)
Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)
Icons to simplely illustrate sensor function
High quality connector
Immersion gold surface
SPECIFICATION
Type: Digital
Power supply: 5VDC

Project 2. 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/O’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 – any will do.)
Jumper Wires for connections
Project 3. Annoying Soil Moisture Sensor with Photon and IFTTT Project
Never forget to water your plants again with this super annoying project. It combines visual, auditory, and textual cues that will prevent you from doing anything else until you provide your plant with much-needed hydration.
A piezo buzzer constantly blares a shrill note, while a super-bright LED annoys your peripheral vision. In addition, this project will send constant texts to your phone reminding you that your plant needs to be watered. Sounds
like fun, right?

Corey McGuire — First of all, this limits the application to LiPo batteries. LiIon
batteries are superior and valid. They are also inherently safer since they can vent
gas build up (as opposed to pouch battery formats, which can't) but they are still …

Walt Kiefer — What I want to do is use it for a text display on a video monitor. I don't
need the overlay function at this time.
