Hatching a new idea with carpc - Toyota Celica, 2002

As far as many know, the capabilities of a car computer are more limited by the imagination ...

Memories of the series and the movie Knight Rider of the same name do not give peace of mind and constantly visit ideas such as "why else stir up such a thing")))

set a task for myself:
displaying information about the open doors separately, the headlights on, the included dimensions, the underbody lights on (and so on) as graphic images, namely photos of my swallow from two angles.

I decided to use the universal controller Carduino Nano for implementation.

Those who are not familiar with the Carduino Nano give a description:
14 digital I / Os, 6 of which can provide a PWM signal of
8 analog inputs with a resolution of 1024 values, for comparison, the Arduino Diecimila has only 6 analog inputs.
Load voltage for each of the outputs 40 mA
Operating voltage of the microcontroller 5V
Input voltage at the power connector 6-20V Microcontroller
type ATmega168
Clock frequency 16 MHz
Program memory (Flash) 16 KB
RAM (SRAM) 1 KB
Non-volatile memory (EEPROM) 512 bytes
Size 18 X 43 mm

Automatic microcontroller reset when program is written
Miniature power-on
LED Indicator LEDs for modes: (TxD), (RxD), (L), (Power)
Automatic detection and switching of power supplies
Using mini USB connector for programming and computer communication
ICSP connector for direct loading the program into the controller.
Standard 2.54 mm (0.1``) pin pitch of output connectors
Manual reset button

The Carduino Nano can be powered from the USB connector, from an external unregulated 6 ... 20 V supply (pin 30 VIN), from an external stabilized +5 V supply (pin 27). The system automatically selects that source.

back to the idea ... we connect
to the digital outputs according to the diagram below

then you will need to write software, which, depending on the state, will display the corresponding images on the screen. Something like this.

from the image on the screen we will see that both doors and the trunk are open ...
now just photos from my album are used as an example ... naturally, photographs of various states will need to be taken from one angle, filming every possible variation ...

if anyone has any ideas or comments, please unsubscribe ... my nubism in programming still complicates the implementation, again I will accept help in this)))

Thank you all!
