I want to implement a simple lighting circuit, which moves from one state to another using a simple momentary switch. The modes are as follows:
Bright mode -> Dim Mode -> Strobing mode -> Off

I want to use only one switch and minimum of components.

 

What's stopping you?

 

Google Search: debounced sequencer with CD4017

Does this give you any ideas?

 

It will be hard to stop it on the desired state.

Controlling the clock?

Here on earth there are 47,139 different kinds of lights (I checked). Which one is yours?

That's exactly the behavior of our TechLite Lumen Master flashlight. Maybe there is a mass-produced flashlight chip that you can buy, or you can harvest the circuit from a flashlight?

Alternatively, why not use an MCU? A simple one like a PICAXE 08M2 is capable of doing what you want, including debouncing the pushbutton. Not that hard to learn, and trivial to program (you just use BASIC). Comes in an 8-pin DIP, that's pretty simple and small. No external oscillators. About all you would need is an external pass transistor to handle the current of your LED.

 

Use a 4 stage ring counter circulating 1000. Clock with the switch, with debounce. Enable each mode by one-hot state.

 

This seems a lot like a homework assignment. Is it?
