Sure -- and that's an easy way to do it. However if I'm going to make it automatic, I like the elegance of using an LED as it's own sensor for how bright it should be. It also uses up fewer microcontroller pins -- for example, I can use pulse width modulation to give the LED a default brightness. Then during the OFF part of the cycle, reconfigure the pin to act as an ADC and make a measurement of the ambient light and adjust the duty cycle as needed.
It's the kind of optimization I enjoy! Another neat trick is using the watchdog timer and counting CPU cycles to allow really low duty cycles for lights you want to keep very dim, without using a resistor to limit current (you are instead using the IV curve on the datasheet and a little math). I use this plus magnets and coin cells to make little lights I can stick to things to avoid hitting my head on them, usually doorframes (I'm very tall and live in Southeast Asia). They run for 3+ years off the cell, and have configurable brightness!
If the device already has a microcontroller then I agree the "high tech" method is more appealing, while for something like a desk fan I think the analog route might be more elegant or at least more robust.
Yeah know what you mean. However these days I can generally get a microcontroller for a lower price than a cds photo resistor, and with a 100 year expected lifetime -- also usually it consumes less power too.
I could do it with a phototransistor more easily than a photo resistor. That would be a solid competitor to using an MCU in terms of cost, performance, and power consumption in a simple system!
Anyway in practice I rarely get to use analog or discrete components professionally. The MCUs are just too damn good.
Good points. I didn't realize even using a dedicated MCU just for that would be the better option.
This struck me as super weird too. It still 'feels' wrong to use a whole CPU instead of a few logic gates or a 555.
It took some getting used to. Maybe soon I'll dive into the world of one-time-writeable Chinese MCUs (the ones I normally use have rewriteable flash). Those are 9 cents a piece!
If they get any cheaper I'll start using them as ballast!
