Oops, apologies there Airportable. I’d obviously forgotten your reference to auto lights/wipers.
Actually, I’ve never tried MOSFET switching, mainly because I’ve never found relays problematic in their switching duties - the frequency mainly, but now you mention it….
Away to France tomorrow for a week so nothing will progress till after.

Yes, this incarnation is ridiculously OTT. However, it got me thinking again of the ‘features’ added to current cars such as auto lights and wipers not to mention my favourite lane ‘assist’.

Rant: If you’re incapable of directing a vehicle within boundaries either side of it then perhaps you shouldn’t be anywhere near the vehicle let alone in charge of it.
End Rant.

Anyhow, now to order an Arduino Nano and a suitable enclosure and get it fitted sans relays.

The latest prototype. The RGB LED’s off EBay are a bit meh on non primary colours. Using relays and a proper 12V supply ensures good colours and brightness. Not exactly space saving though. Even more OTT!! Decisions, decisions.

Hi,
Black ice in Oz? That does surprise me.

IMHO Rasps are far too bulky and OTT for this ( and other) added car features. The final version will be on an Arduino Micro or Nano, I’ve only got the UNO’s. Might have to use relays for a 12 V supply to the LED’s as some(the yellow one) are rubbish at the voltage pushed out. Unfortunately, that’ll mean I can’t use the PWM outputs so no colour mixing…..I’ll see how the RGB LEDs behave when they arrive.
Interesting how I went and bought a car that’s relatively simple from the onboard ‘tronics point of view and start adding ‘tronics! At least I know where they are and how to rip ‘em out if they start with a bad attitude.
Cheers,
Michael.

Hi All ,
One thing I think I’ll miss come the winter is an external outside air temperature reading or indicator.
Being someone with definite geek tendencies rather than go and buy an off the shelf widget, which would be boring I rigged this up:









Using the Arduino processor board and three LED’s to indicate cold(green), normal(yellow), and hot(red) with changeover temperatures of 20 and 25 Celsius; green below 20, yellow between 20 and 25, and red above 25.
The final incarnation will be just one RGB LED mounted somewhere that it’ll give a coloured glow of probably one of 6 colours - deep blue for anything below 5 C, maybe light blue for 5 to 10C, light green for 10 to 15, green for 15 to 20, orange for 20 to 25, and red for 25 and above. Just waiting on delivery of the RGB LED’s.
I suppose I could add a buzzer or some audio warning below 5 C although I think commercial manufacturers use 3/4 C.
Anyways now I’ve admitted to having too much time on my hands, I’ll bid to a good day.
Regards,
Michael

Turning up as in on a lathe? Ouch !!!
I too have had a re-think. I need to wait till I’ve got a spare pair of eyes and hands available to man the hosepipe while I do the relevant checks down below. That’s what the Good Lord created younger brothers for after all.
Cheers,
Michael.
