Arduino Basics

  Description Using the HMC5883L magnetometer sensor of the GY-80 module from ICStation to monitor a garage door and notify when it has been opened or closed. The Cayenne service provides much of the monitoring and notifying functionality. A major feature of this project. Cayenne takes care of all of the complicated work behind the scenes, making it easy to connect your Arduino to the cloud and allow you to monitor your garage from virtually anywhere.   This project was created specifically to monitor a garage, but you will soon discover that this project could be used to monitor a whole host of other things. Monitor your front door, your back door, your bag, your chair, your cookie jar.   Monitor for peace of mind, or catch someone in the act of stealing your stuff. This project has got you covered. Let's see how:   Part...

Project Description We will be using an MT8870 DTMF module with an Arduino UNO to control a small servo motor in this project. The DTMF module gives the Arduino super-powers and allows you to control the Servo motor in so many ways. For example, this tutorial will show you how to control the servo motor using: a YouTube Video a voice recorder A web application (Online tone generator) A smart phone app (DTMF Pad) A touch-tone phone to cell-phone call All of these control methods will take advantage of the same exact Arduino code/sketch. But how??? The MT8870 DTMF decoder is quite a neat little module that allows you incorporate DTMF technology into your arduino projects. DTMF stands for D ual- T one M ulti- F requency. DTMF tones are commonly associated with touch-tone phones and other telecommunication systems. When you press the number "1" on a touch-tone phone, two sine wav...

This project makes use of Seeedstudio's Grove Sound Sensor. Which essentially gives your Arduino ears ! The small sound sensor (microphone) attaches to an Analog pin on the Arduino and can be used to detect the level of noise in the surrounding environment. You could potentially use this sensor to turn a light on in your house after recognising a specific clap/whistle sequence. In this tutorial we are going to connect a few LEDs to the Arduino, and get it to listen for a click/clap, and respond accordingly. Have a look at the video below for this project in Action. Parts Required Arduino UNO or compatible Grove Sound Sensor Grove - Base Shield Protoshield Headers LEDs and 330ohm resistors Mini Breadboard 4.5cm x 3.5cm Grove Universal 4 Pin Cable Breadboard Jumper Wire Assembly Place the Grove Base shield onto the Arduino UNO or compatible microcontroller. Solder some headers onto a ProtoBoard and then stack this onto the Grove Base Shield Stick a Mini-Bread board onto the ProtoBoa...
