Putting the pieces together
Go ahead and create this circuit for Arduino:
The connections are as follows:
- PIR → Arduino
- GND → GND
- OUT → D02
- VCC → 5V
- HC-06 → Arduino
- VCC → 3.3V
- GND → GND
- TXD → D10
- RXD → D11
Don't get mad, but there is one last library that you need to install in order to allow Arduino to communicate with Python: pySerial. Go to https://pypi.python.org/pypi/pyserial, download pyserial-2.7.win32.exe, and install it just like you install any other software. Then, we are ready.
Open Arduino and load the alarm_bluetooth.ino file that came with this chapter. It is recommended that you have the most up-to-date Arduino software before proceeding:
