Once you have the image burn on the SD card and the Bluetooth control application on your phone it is time to connect with the phone to the Raspberry Pi.

TL. DR.
When connecting to the Raspberry PI with the Phone the diode will blink to indicate a successfull connection. We use a Bluetooth connection.
Connect indication
The goal, at this step, is to connect the phone with the raspberry pi and to make sure that when connecting with the phone to the Raspberry PI the diode will blink. This is the simplest indication we could implement. When the phone connects to the Raspberry PI the diode will blink.
The diode already blinks when starting up the Raspberry PI?
Yes, it is true. When we power the Raspberry PI and the operating system is loaded the diode will blink. It will also blink when connecting to the Phone. It is possible to use two different diodes for this, but we've decided to use a single diode to make it very very simple.
How to connect?
The connection process is the following
Start the raspberry PI
Open Bluetooth settings on the phone and find the "PerfectPi" device.
Click on the PerfectPi device. It will be automatically paired. Nice. We've done some magic here for this automatic pairing to work without requiring any passwords.
Open the Bluetooth communication application on the phone and you will see the PerfectPi device.
After connecting you will see the diode blink

Perfect STEM course. Module 1 - Smart Car with Raspberry PI
Disassemble a remote control car. Change the brain of the car with a smart computer like Raspberry Pi. Build a smart device with artificial intelligence that you could control from your phone and that could freely navigate itself in the real world and on the Internet. Use your hands. Develop programs for your robot and your phone. Be curious and invent.
The perfect course lives up to its name. You move through the content, we check it and return feedback to you.
In the end, you should be able to better understand how to program and design smart devices that would make the world a better place. For everybody age 12+, 16+, 21+, 35+, etc. The hardware costs about 150$. It changes through the years so it might take some time for you to find it as Raspberry PI, motor drivers, power banks and h-bridges.. they change. Note that the course was designed to be led by a teacher with a decent knowledge in embedded hardware and software. This, on the other hand should not stop you, if you are curious.

Phone to Controller Indication with Diode
This section depends on the fact that the diode is already connected. If the students have not connected it you should return them to the previous section and connect the diode again.
