ProxioSence

This project contains the source code for an arduino based prototype.

This project uses the Arduino IDE to build and upload the sources to an Arduino Nano 33 BLE Sense. We use an RPLidar A1 with 8 Grove Vibration Motors.

Setup

1. Install AruinoIDE
2. Open it, set Sketchbook location under file -> preferences to this folder
3. Code
4. Connect the Arduino
5. Upload
6. ???
7. Profit

Pinout

Pin Name	PIN	Type	PWM	Use
lidarRxPin	0	Input	❌	Serial RX for Lidar -> Arduino communication
lidarTxPin	1	Output	❌	Serial TX for Arduino -> Lidar communication
lidarMotorPin	2	Output	(✅)	Controll the motor of the lidar. Always HIGH
NorthPin	3	Output	✅	Controll the vibration strengh on the north side.
NorthEastPin	4	Output	✅	Controll the vibration strengh on the north east side.
EastPin	5	Output	✅	Controll the vibration strengh on the east side.
SouthEastPin	6	Output	✅	Controll the vibration strengh on the south east side.
SouthPin	7	Output	✅	Controll the vibration strengh on the south side.
SouthWestPin	8	Output	✅	Controll the vibration strengh on the south west side.
WestPin	9	Output	✅	Controll the vibration strengh on the west side.
NorthWestPin	10	Output	✅	Controll the vibration strengh on the north west side.

Schematic

The schematic can be found at schematic.png. Just keep in mind that this schematic shows an Arduino Uno and not an Arduino nano 33 BLE that is required for this project. Building it with an uno and keeping the same pinout as the schematic shows will not work, simply because the nano 33 BLE has PWM control on different pins than the uno!

Model

All individual components that have to be printed can be found as .obj files in the assets folder. A complete model showing the final assembly is available in assets/ProxioSense - complete model.zip.
