I don't know what you are, but there is no car, in addition to the bus, the preferred travel method is Uber. As a person who is determined by a workplace location, the family, the company and the shopping center are three places that are often taxed. Every time I use Uber to take a taxi, I need to take out my mobile phone, choose service, etc., if I can have a button called the car!
Of course, there is no such tool on the market that does not mean that we can't have such a tool, but we have a pair of hardworking hands, then do it yourself.
Step 1: Tools and components
Arduino Mega 2560
1Sheeld
Button
2 seven paragraphs of digital tube
LCD 2x16
USB
PCB
15 330Ω resistors
Small breadboard
Wire, etc.
Plywood used as a shell
Step 2: Uber box
The design of the Uber box is of course related to other materials you choose, if you use the same LCD (70x25 mm), digital tube (12.5x19mm), buttons (30mm diameter), you can download Uberbox.ai file as a box Cutting standard.
Step 3: Test LCD
Of course, if you make sure your LCD is intact, this step can be omitted.
You can test the LCD and related connections in accordance with the connection method and code LCD_HELLOWORLD__. INO.
Step 4: Test seven paragraphs of digital tube
Test the digital tube and need to use the breadboard. The connection method is shown below:
in:
A connected 22,23 feet
B connection 24,25 feet
C connected 26, 27 feet
D connection 28,29 feet
E connection 30,31 foot
F connection 32,33 feet
G connection 34,35 feet
Note that a 330Ω resistor is required between each of the digital tubes and Arduino's connections.
The test code is _2Digit_segments.ino.
Step 5: Making a PCB board
After the test is completed, you need to make a system that can be used for a long time. This is not to say it.
Be
Step 6: Connect the button and the 12th
Note that the pin selection here is actually defining the pin according to your own needs, but also needs to modify the code of Arduino.
Step 7: Access to Uber API
In order to be able to use Uber, we need to access our apps through the Uber's API, so you need to get access token on the Uber developer website. Here we can use Sandbox services.
Note: If you are using Firefox browser, recommend an interesting associated plugin RESTCLIENT, which helps you test a variety of web services.
Add the following to your head:
Authorization
Bearer Oauth2-Key

{"START_LATITITUDE": "Your_LAT", "start_longitude": "Your_long"}
The process of execution of the command is as follows:
Release
Https://sandbox-api.uber.com/v1/requests
{"start_latitude": "Your_LAT", "start_longitude": "Your_long", "Product_ID": "Product_ID"}
2. Push
Https://sandbox-api.uber.com/v1/sandbox/requests/request_id_from_previous_request_response
{"status": "accepted"}
3. Get
https://sandbox-api.uber.com/v1/requests/same_request_id
The code that needs to be configured on Arduino is as follows:
Ubersandbox_public.ino
Ubermain_public.ino
Eight step eight: The final assembly
Put the various parts into the box to fix it.
Test it.
