Grove Button Tutorial

-
The Grove Button is a handy little component which simplifies the push-button experience. It doesn't take much programming to get this component to work. And while the button works extremely well with the Grove Base Shield, we will be connecting this button directly to the Arduino UNO.

The button will be LOW in its normal resting state, and report HIGH when the button is pressed. Have a look at the video below to see this project in action.

 void setup(){
   pinMode(8, INPUT);
   pinMode(13, OUTPUT);
 }

 void loop(){
   digitalWrite(13, digitalRead(8));
 }

The signal pin of the Grove Button attaches to digital pin 8 on the Arduino, and the LED is connected to digital pin 13 on the Arduino. When the button is pressed, it will send a HIGH signal to digital pin 8, which will turn the LED on. When the button is released, the signal will change to LOW and the LED will turn off.

Have you ever wondered if there was a way to store and retrieve data from a USB stick with an Arduino UNO? Most people choose SD cards to store their project data, but you may be surprised there IS a way! IC Station have a nice little module which allows you store and retrieve your Arduino (or other MCU) project data to a USB stick.   I am not too sure why USB storage is not widely used in Arduino projects? These modules are not expensive, they have been around for quite a while, and are relatively simple to use. You do not need any libraries to get them to work, however, I must say that documentation for this module is not that easy to find. This site and this document proved to be very useful in my endevour to get this module working, and I hope my tutorial below will help you get started and bridge some of the information gaps.   The...

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 ...
