I just want some advice about my project. I'm a beginner in electronics, programming and also arduino.
It's a dashboard of a Baja (off-road car) with an arduino UNO and three Hall effect sensors to measure speed, rpm and fuel level. It has two 7 segments displays to indicate the speed, six leds to indicate rpm and four leds to indicate fuel level.
I found an IC MAX7219 to bind all these leds and i'm having some doubts to project it.
I want to know if it is correct and if it needs some additional components. Regarding the programming, i want to know if there is an easier way to project it.
I've developed the design using Proteus >
Thank you very much in advance!
