Light Bluetooth

LED light that operates off iPhone app. Apple does not let you may your own iPhone apps. The only way I could find to control Bluetooth with my phone was with Dabble.

You must download Dabble app on your phone.

I used:
Common anode RGB light and 100K ohm resister on each leg
Bluetooth module: HM-10
Arduino Nano
Nano I/O Breakout Expansion Board Shield

The shield is used so NANO can be removed for other projects.
Bluetooth is attached using small perf board and header pins - allows easy removal of Bluetooth.
Resisters are attached using small perf board - done to keep wires neat


LED legs are connected to NANO pins 5,6, and 9 - Red, Green, Blue - ground leg connected to ground. A 100K resister is in series with each color leg

HM-10 VCC to NANO 3.3 volt
GND to NANO ground
TXD to NANO pin 2
RXD to NANO pin 3

DABBLE uses pins 2 and 3 for TXD and RXD - it is a clever set-up - allows upload
