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
