Hi,
I’m relatively new to BBC microbit and coding, total noob! So here’s what I’m trying to achieve…
For background I have a VW beetle (Herbie) rigged that doors open, lights flash, horn sounds etc via a 12ch remote and relays, this works very well and seems to be robust.
I’d like to add a number plate that wags a bit like a dog’s tail.
I’ve currently got a micro bit and and small hobby servo to understand the code and it operates more or less as want it to, however for strength and longevity I need it to run on a higher voltage servo, somewhere around 8-12v.
It also needs to trigger via the 12 ch controller as way of input signal. This also operates at 12v.
What are my options in terms of driving the servo? I’m looking at the Kitronic 16 servo board as this reads as though it can handle 12v input and output.
Any thoughts on the input signal?
Thanks for any help you can offer.
Jamie
Update on the above, after playing around with different servos I got the speed and motion I needed. See YT video below:-

Only thing is I managed to accidentally put 12v through my micro:bit even using a voltage dropper, though I suspect it wasn’t robust enough.
I have other components on the car already for operating pneumatic doors that open, horn beep, lights flashing, which operate via a 12v 12ch RF controller using momentary signals.
What I’m looking to achieve is to switch on and off the micro:bit in the same manner (rather than sending an input signal to one of the pins). This feels like a work around but I’m happy with my basic code and function. My code is “on start up….”
I’m going to bench test this later this week but hoping using a more robust buck I’m not going to cook my micro:bit again.
Could anyone comment if this looks like it should work or will it be micro chips for dinner again!
