The article explains driver installation with Arduino IDE for Vortex, describes Bluetooth communication protocols, outlines the use of infrared sensors for obstacle avoidance, and offers instructions for customizing system voice using the MP3 switch.
Driver
it will install the driver automatically if you have installed Arduino IDE. If not, you can find it in the driver file in Arduino IDE folder-->Drivers folder.
Library
Communication Protocol Description
Vortex supports Bluetooth wireless communication, you can refer to the Bluno wiki page for the Bluetooth configuration and firmware upgrade.
Principle
- Vortex is using 2 pairs of Infrared transmitter and receiver as its obstacle avoidance sensor. The transmitter will send 20 pulse at 38KHz frequency. Since the obstacle will reflect infrared light, we can judge the distance via the feedback pulse.
- Vortex is using optical-electricity encoder.
Other Supplementary Information
Do you still remember the MP3 Switch in the USB programming section? There is a switch close to the USB port, make sure the trigger is close to the USB side. This is MP3 switch, we'll teach you how to add new song in the following chapter.
Now here we go, we'll tell you how to replace vortex system voice with your own one.
1.Turn the switch trigger to the opposite side (away from the USB port).
2.Connect Vortex to your computer via USB port. and it will appear a new flash disk.
3.Rename your voice or your song file, and put them in the disk.
NOTE: The MP3 chip recognizes the file by the modified time, not its name, so you will need to rank the file again! Just cut all file outside, and move them in the disk in order.
