Hello, I'm hoping for some help designing this circuit.
- UK mains power
- a single wall dimmer switch
- a lamp
The lamp is made of...
- 5 or 6 bulbs, one above the other up a wall
- lower bulbs are orangey warm red like sunset
- higher bulbs are cool white like mid day sun
- as the dimmer is rotated from minimum to maximum first the lower bulb gradually comes on. As it is getting brighter the bulb above begins to come on too, but not as bright as the first bulb. In turn each bulb comes on until maximum when they are all on full. The first bulb should be fully on by the time the dimmer is about half way.
The effect should be something like the rising sun.
I could do something digital with an arduino, PWM modulation and LED bulbs where I have a bit of experience but I'm hoping there's a more robust way this could be achieved with resistors and maybe capacitors, things I know less about.
The wall cabling is done already so I cannot change that. One distribution board in the middle with a twin and earth cable off to the switch one way and another off to the lamp socket the other way.
Any help very greatly appreciated!
