Arduino Basics

  Description This is an Arduino based home security project that uses the power of "Cayenne" for extraordinary capabilities. Cayenne Beta Cayenne is a new IoT drag and drop platform originally released for the Raspberry Pi, but now available for Arduino. Cayenne makes the task of connecting your Arduino to the internet as simple as possible. All of the complexity of internet connectivity is hidden within the Cayenne library. You can easily create a Network of Arduinos and build an IoT system which can be managed and operated within the Cayenne dashboard. This dashboard is accessible through your browser or via the Cayenne smart phone app (on IOS or Android). The feature I liked the most, was the ability to change the position of sensors or actuators on the Arduino without having to re-upload Arduino code. I could manage the changed position from wi...

Create your very own Arduino BeatBox ! Home-made capacitive touch sensors are used to trigger the MP3 drum sounds stored on the Grove Serial MP3 player. I have used a number of tricks to get the most out of this module, and I was quite impressed on how well it did. Over 130 sounds were loaded onto the SDHC card. Most were drum sounds, but I added some farm animal noises to provide an extra element of surprise and entertainment. You can put any sounds you want on the module and play them back quickly. We'll put the Grove Serial MP3 module through it's paces and make it into a neat little BeatBox !! Key learning objectives How to make your own beatbox How to make capacitive drum pad sensors without using resistors How to speed up Arduino's Analog readings for better performance How to generate random numbers on ...

Add sound or music to your project using the "Grove Serial MP3 Player". An Arduino UNO will be used to control the Grove Serial MP3 player by sending it specific serial commands. The Grove Base Shield allows for the easy connection of Grove sensor modules to an Arduino UNO without the need for a breadboard. A sliding potentiometer, switch and button will be connected to the Base shield along with the Serial MP3 player. A specific function will be assigned to each of the connected sensor modules to provide a useful interface: Sliding Potentiometer – Volume control Button – Next Song Switch – On/Off (toggle) Once the MP3 module is working the way we want, we can then build a simple enclosure for it. Grab a shoe-box, print out your favourite design, and ...
