If you have multiple IDEs installed, rename them so you don’t get confused! e.g. “Arduino”, “Arduino-GEMMA”, “Arduino-FLORA”) • FLORA: learn.adafruit.com/getting-started-with-ﬂora/download-software Note: On Mac Mavericks, change your Security & Privacy settings to “Anywhere” to launch IDE. Then restore your settings back to normal afterwards. 2. Plug in the FLORA via USB and conﬁgure Arduino IDE Tools > Board > Adafruit FLORA Tools > Serial Port > /dev/tty.usbmodemXXXXX (Mac) or COMX (Windows) 3. Open up the Blink sketch Check the USB thumbdrive for: Adafruit FLORA > Sketches > Blink > Blink.ino Note: Pin 7 (the internal red LED does not support PWM so you can’t use Pulse.ino on that pin) 4. Upload the sketch
e l e ro m e t e r N E X T S T E P S 1. Download and install the Adafruit_LSM303 library learn.adafruit.com/ﬂora-accelerometer/programming Place the “Adafruit_LSM303” folder in your Arduino libraries folder (e.g. ~/Documents/Arduino/ libraries) and restart the IDE. 2. Open and upload the LSM303 “Test” sketch. From Arduino menu: File > Examples > Adafruit_LSM303 > Test 3. Use alligator clips to complete the following circuit: (Use USB or battery power.) 4. Open up the Arduino serial monitor. Move the accelerometer around to see logged values.
y p i n g U S I N G T H E F LO R A F O R : • Ideal for soft-circuit prototypes. • Use alligator clips (or just twist wire onto the pads) to test ﬁrst circuit designs. • Ecosystem of FLORA accessories/modules available: Bluetooth, GPS, 3-axis accelerometer, compass module, ﬂex sensor, piezo, IR LED, push button, embroidered + capacitive keypad, OLED and more.
