![]() ![]() ![]() Modifying the Arduino toneMelody example is as simple as adding a line and modifying two lines: #include "pitches. With this configuration playing a tone on the buzzer is as simple as: void setup() Positive terminal connected to D4 and negative terminal connected to D5. I happened to mount mine with the words up and positive terminal down. It seems the buzzer can be mounted either end up. It took me a minute or two to figure out the buzzer so I posted a quick write up at TechSpin/Arduino Pro Buzzer. Digital IO: 12 digital I / O (5 with PWM capability) Serial Interface: Rx and Tx hardware serial connection. **Note: **A portion of this sale is given back to Arduino LLC to help fund continued development of new tools and new IDE features. Programming / Debugging Interface: Micro USB connector. Not sure which Arduino or Arduino-compatible board is right for you? Check out our Arduino Buying Guide! We've also populated it with a sturdier power selection switch. In this latest version of the Arduino Pro we've also moved the FTDI headers back* just a skoach* so that the pins don't hang over the edge of the board. The Arduino Pro also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. ![]() This board connects directly to the FTDI Basic Breakout board and supports auto-reset. Also, to keep the cost low, we made changes like using all SMD components and switching to a two layer PCB. We recommend running the board with a LiPo battery for better portability. To keep things affordable and low profile, we've chosen to make the DC power jack footprint available, but not to populate it. The Arduino Pro series is meant for users that understand the limitations of this lack of connectors and USB off board. It's a great board that will get you up and running quickly. We recommend first time Arduino users start with the Uno R3. This is a 5V Arduino running the 16MHz bootloader in a super-sleek form factor that will fit easily into your next small project.Īrduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. It's blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach to Arduino. ![]()
