Hi,
I'm trying to design a clock with hands that change colour at a certain angle. To do that I want to use a heat reactive paint which changes colour when heated around 40 deg (C). I've attached a diagram of the possibilities that apply to the colour change.
My question is what's the best way to design the clock so that it automatically changes the colour of the hands? I've started thinking about the components, but not sure if I'm in the right direction.
- Nichrome strip to heat up the hands of the clock
- Motion sensors embedded in the body of the clock to detect the location of the hands.
I'm fairly new to electronics, so simple instructions will be very appreciated.
Thanks for your help in advance.
