<p class="p__0">2 common questions we receive: 1. How can I use more than one 8x8 matrix backpack in an Arduino sketch? 2. We have actually had creepy Halloween screens on the brain lately, but the ideas here are similarly appropriate to more benign principles. Craft stores have these terrific reasonable styrofoam skulls around Halloween time. Here we're using LED matrices for just</p>

<p class="p__1">the eyes, no mouth( the" roboface" sketch will work all the same). The eyes peer around and blink. These LED backpack display screens utilize the Arduino's Two Wire Interface( or TWI though you'll also sometimes see this called IC, Philips' trademarked name for the company's original implementation ). TWI permits numerous devices to communicate on the very same bus. Simply This Is Cool are requiredyou don't require to commit Arduino pins to every different gadget. Newer "R3" Arduino boards also consist of distinct SDA and SCL pins serving the very same functions, though analog pins 4 and 5 still work too. In order to differentiate amongst several gadgets on the bus, each should be assigned a special numeric address. Most devices( sensors, etc) are factory-configured for one specific address, however others( like these LED backpacks) are at least partially configurable. Bridging the "A1" box will add 2, and both can be used in combination for 3. This allows 4 possible addresses on the" mini" 8x8 matrices. The" small" matrices include an" A2 "address selection which includes 4 to the gadget's address (once again usable in mix, so there's an overall of 8 possible addresses with the small matrices ). We prepare to use a small 8x8 matrix for each eye, and 3 side-by-side to form a mouth. But there's only 4 addresses, and we have five matrices! So we'll utilize a little compromise here: both eyes will constantly point the exact same instructions and blink togetherno winking or crossed eyes.</p>

<p class="p__2">( And that's all there is to thatsorry if you were anticipating a more technical treatment!) The 3 mouth matrices are then each designated a distinct address, separate from the "eyes" address. Here's the view from the back: Turning this over then, our circuitry diagram will look something like the following.</p>

The buttons are optional one of the example sketches(" wavface ") interacts with a Wave Shield, and these are used to trigger noises. A simpler example( "roboface") does not require the Wave Shield</p>
