Arduino speaker connection bi

This particular project, by Instructables user zvizvi comes with a list of predefined emoticons, each assigned to a single digit and matched with a uniquely colored LED. Then gently remove the flat, opaque disc located behind the finger holes of the dialer. Keeping in mind where the finger holes are, drill 10 3mm holes into the plastic behind the dialer. Also, remember to leave some wire at the end to connect to the Arduino. Connect the ends of these wires to the MCP or the Arduino and test your connections, making sure all LEDs are mounted firmly and light up when connected to 3V power. Replace the opaque disc and the the dialer and re-test.

Bi-Directional Logic Level Converter Hookup Guide

To get over this obstacle you need a device that can shift 3. This is called logic level shifting. Level shifting is a dilemma so common we designed a simple PCB assembly to make interfacing devices a little easier: the Bi-Directional Logic Level Converter.

The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3. Though they're share the same shape and size, this bi-directional logic level converter shouldn't be confused with the more "uni-directional" version.

It's perfect for level-shifting between devices that are sharing a data wire, like I 2 C or a one-wire interface. We'll examine the schematic and board layout -- explaining what each pin on the board does.

At the end we'll go over some hookup examples to show how you might hook the board up for various interfaces. If you take a peek at the board's schematic , you'd find that the bi-directional logic level converter let's shorten that to BD-LLC is actually a very simple device. There is basically one level-shifting circuit on the board, which is repeated four times to create four level-shifting channels.

A 0V signal on one end remains a 0V signal on the other. One row contains all of the high voltage e. The pins are labeled on both the bottom and top sides of the board, and organized into groups. Let's look closer at some of the pin groups:. Supplying a steady, regulated voltage to both of these inputs is required.

For example, if you're interfacing from 5V to 3. There are four separate data channels on the BD-LLC, each capable of shifting data to and from high and low voltages.

The number at the end of each label designates the channel of the pin, and the HV or LV prefix determines whether it's on the high or low side of the channel. A low-voltage signal sent in to LV1 , for example, will be shifted up to the higher voltage and sent out HV1. Something sent in HV3 will be shifted down and sent out of LV3. Use as many of these channels as your project requires. You don't have to use every single one. Keep in mind that these level shifters are purely digital.

They can't map an analog voltage from one max voltage to another. There are a lot of options here. You could solder straight male headers in, and plug it right into a breadboard. Or perhaps you want to solder wires directly into it. Pick an assembly method that melds with how you intend to use the board. Your hookup will probably vary depending on which communication interface you're using. Below we'll show how to hook the level converter for three of the most common communication protocols.

Although you won't be taking advantage of the BD-LCC's bi-directional abilities, it's perfectly fine to use the board to shift serial communication. Serial usually requires two signal wires -- RX receive and TX transmit -- which both have a defined direction. Let's say, for example, you want to hookup an Electric Imp Breakout Board which has a 3. Here's one possible hook up:. Please note that the Arduino and the Electric both have their own power supplies in this example.

Make sure LV is powered at 3. Double-check that the channels match up, and a-shifting you will go! You've even got two extra channels to shift as you please. We can even add another I 2 C device Since I 2 C is only a two-wire interface, we have room on the BD-LLC to fit in a couple of extra signals, like the interrupt outputs from each board. The two 3. Even more I 2 C device can be added, as long as they have unique addresses.

Arduino Led Matrix Example. I soldered 2 matricies with MAX chips and will see it runs on it. You can then easily draw shapes, text and animation without having to calculate every X. Open the sketch for this section. The power on and single row and single column will turn on a single LED. It then scrolls to the left while the next. The MAX chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board.

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the ISM bands , from 2. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. In the most widely used mode, transmission power is limited to 2. Bluetooth is managed by the Bluetooth Special Interest Group SIG , which has more than 35, member companies in the areas of telecommunication, computing, networking, and consumer electronics. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks.
