External LEDs and Buzzer

[robshaw]

So after fitting my new APM to my TBS I found it quite difficult to see the status LEDs for GPS and Arm.
To do this I decided to use 2 of my already fitted orientation LEDs, a 12v buzzer and a Darlington array IC.


Parts


The strip board cut and tracks cut.


IC header soldered in.

IC header and pin headers soldered in.

IC plugged in to complete the module.

I then connected A5, A6 and A7 of the APM to the first 3 inputs of the Darlington array. The neutrals of the LEDs and the buzzer connect to the the opposite outputs. And just a neutral the pin 9 of the IC. All the positives are connected to 12v on the power distribution board.

I then changed LEDmode in the parameter list to 11 and the write params.

And here are the results.

As you can see the left strip indicates GPS lock and the right strip is for armed/disarmed. If you listen carefully you can here the buzzer also indicating arm/disarm.
Simples.

Doh!  Try again mate.

Working now, done similar on my Q650 but with ultra brute LEDs. Yours look fab.
