Profile

Developing Python App on Raspberry Pi
*** Please read this. If you cannot deliver this in 5 days or less AND have not done anything like this before, please do not apply ***
*** Please message me samples of apps similar to this ***
Raspberry pi OS / Pi 3 B hardware
Other hardware: pi camera, pi 7 display, buzzer, HC-SR04 ultrasonic
Code: Python (code samples for ultrasonic & buzzer will be given)
Need a python application that does the following:
* Display will display the text in white big capital letters across multiple lines
APPROACH DISPLAY SLOWLY TO ACTIVATE TEST on a black background which covers
the entire display
* Cars will drive up to the display that is on a wall, once the ultrasonic
senses they are within 150 cm they will see the display change to an overlay
talked about below and nagivate a specific part of their car in the square on the display
until they are within 50 cm
* Displays a real-time image on the display (no borders, menus, etc. from the camera)
* Has an overlay of a centered bracketed box on a specific part of the image on the display
as shown below
i.e.
(See attached [login to view URL])
where bracket height should be red color and adjustable in size vertically and horizontally
and the entire image the camera sees is shown on the screen
* When they get to 50cm to 20 cm, they will get 1 buzz to let them know to stop.
* They will wait for 3 seconds and then get another buzz to let them know to backup.
* During the 3 second time they are waiting - they will have an image (picture)
taken BUT after the 3 seonds, the app will have the image placed that was just taken
on the display with an overlay of the word Pass in green text in the bottom right
of the image. If they get closer than 10 cm during the 3 seconds, it will put red
text in the bottom right of the image of Fail.
* After displaying the image for 5 seconds, the app will loop to the top
of this program displaying the original text described in the first bullet
**** Lastly... since the app takes up the entire display, it should not be able
to be stopped via the touch screen or keyboard on the display
