Pulse width modulation (PWM) for LED instrument illumination

[Philip Wardle]

Hello all

Has anyone have sourced a robust and reliable PWM module, or have any experience they're will to share?

Cheers

Did use a Audino to control speed of a motor, which could be easily adapted to control the brightness of the lights by PWM. All that really was needed to do it was the Audino CPU and a solid state relay.

I bought some mickey mouse LEDs out of China and they do dim. . I lost the contact. The next set I bought for Stag no. 2 dont.

I used one of these, https://www.amazon.co.uk/12V-14V-Dim...008TNH68E?th=1, other suppliers available.
Reboxed it so that pot was mechanically connected to original dimmer.

One problem I found with available 'cheapie' ones is that they are positive ground. Perhaps not all are like that? But they are so cheap it's worth experimenting with one or two.

Thanks chaps, some useful ideas and suggestion to follow up on.
