Digital OAT Gauge

 

Design for the OAT gauge is based on Electronics International OAT (see end of this page):

Ice warning indicator on (OAT between -12 and +4 degrees celcius)

Above the design made in Front panel designer

Real panel

 

 

 

To display the temperature (Celcius) I'm using 3 x 7segments LCD, 

   

Picture above: Components

the first '7-segment display' is only to show the minus "-"sign if the oustside temp is below zero degrees Celcius. Therefore I only use pin3 (segment 'g', the minus sign) and pin1. I use a (opencockpit mastercard) basic output to put this sign on/off (use a 150 Ohm resistor, because mastercard output is 5V and this segment display only 2 Volt (I added an resistor table in the 'manual'section)).

The 2nd and 3rd '7-segment display' are connected to the Opencockpit displaycard.
