This project uses the Adafruit Bluefruit LE connect app (available free for Android and iOS) to trigger the lights and sounds. It uses the Color Picker module to choose different colors. If you haven't downloaded the app yet, use the button below to install it on your mobile device.
Turn on the Feather by either connecting it via USB to your computer or with the slide switch.
Open the Bluefruit LE Connect app and locate the device named CIRCUITPY and tap the connect button. Locate and tap on Controller. Under module, tab on Color Picker.
You can change the color of the NeoPixel LEDs by using the Color Picker. Tap connect, select Controller. Under module, tap on Color Picker. Use the color wheel to select a color and the slider to adjust the brightness. Tap the send color button to trigger the color.
If you have an Apple Watch, you can use the Bluefruit LE Connect App just like the mobile app. The Apple Watch app is included with the iOS app download.
