A simple DIY LCD and LED bars panel with Arduino

Hello guys.

I’ve done a second project with an Arduino Nano, 2 LCDs and 2 LED bars to:

  • display NAV1 & NAV2 Active and Standby frequencies

  • edit and switch NAV1 & NAV2 Standby frequencies

  • display and edit radial setting of NAV1 & NAV2 (OBS)

  • display and edit ADF frequency and HDG

  • when a NAVx starts receiving a valid signal, the program automatically displays its CDI on 2 LED bars

  • on a second LCD the program displays Indicated Air Speed, Altitude (QNH), Height (QFE), HDG and Vertical Speed

Looks like a fun project. I have everything but the led light bars. Might give it a go.

About “Grove LED Bar”, i’ve bought the V2.0 version but i don’t really know what’s the difference from the previous one (probably the colour of the last 2 or 3 LEDs?).
However i think you could buy them online without any problems.

Let me know if you start to build your panel :slightly_smiling_face:

P.S.
You can find the links where i bought all the components at the bottom of the project description

Great idea to use an LED bar to display course deviation! Very innovative. Starts me thinking where else a native electronics display would make sense to build instread of using computer screens to display gauges.
The excellent Caproni C22J has an odd engine instrument that is comprised of LED bars. That could be a candidate.
Thanks for sharing your design!
