Arduino Hardware

You will notice that the arduino has 32 holes which are called pins.

Arduino hardware. The arduino uno has 14 digital pins 0 13. Most arduino designs have two hardware interrupts referred to as interrupt0 and interrupt1 hard wired to digital i o pins 2 and 3 respectively. The arduino mega has six hardware interrupts including the additional interrupts interrupt2 through interrupt5 on pins 21 20 19 and 18. The arduino now has the data it needs to determine if the light should be on or off.

The current basic board the duemilanove uses the atmel atmega328 datasheet. I entered the smd world years ago when i dug into arduino pcb design while i was a part of a team redesigning a diy clone for arduino uno. The starter kit is a great way to get started with arduino coding and electronics. Shields are additional boards that usually follow the form factor of the arduino uno and can be attached to the arduino to add different functionalities.

Hardware there are multiple versions of the arduino board. You can read and write sensor data through the arduino and immediately see the results in matlab without having to compile. Download the previous version of the current release the classic arduino 1 0 x or the arduino 1 5 x beta version. The starter kit includes the components you need to make 15 fun projects following the step by step tutorials on the project book.

Arduino products browse the full range of official arduino products including boards modules a smaller form factor of classic boards shields elements that can be plugged onto a board to give it extra features and kits. This provides data and current. It also has a slot for external power supply. Arduino starter kit multi language.

So for output we take a wire from the arduino digital pin 9 to a new row on the breadboard. In addition to powering up the arduino uno hardware the power supplied via the barrel connector can be accessed at vin to power up components on the breadboard or arduino shields. The older diecimila and the first run of duemilanoves used the atmel atmega168 datasheet while older boards use the atmega8 datasheet. All the arduino 00xx versions are also available for download.

The pcb design of the arduino uno uses smd surface mount device components. The bases of each pin are conductive. The arduino ide can be used on windows linux both 32 and 64 bits and mac os x. Matlab support package for arduino hardware enables you to use matlab to communicate with an arduino board.

The grounding wire goes from that row on the breadboard back to the arduino completing circuit circle 1. If you need more info you can compare the specs of each board here.
