The example in this episode about a potentiometer-controlled PWM seems like something that made sense about 10 years ago, but no longer does.

The argument against using a microcontroller involved an Arduino, but that's a straw man: you could just as well use a PIC12F1571, which has an on-board ADC for reading the pot and an on-board PWM for generating the signal. If you need more than that, the PIC also has a built-in comparator and other niceties you don't get with the 555 timer + comparator + passives lash-up Chris Gammell hinted at. The µC option also takes fewer parts, takes less board area, and is probably more reliable as a result. The accuracy limit for the µC solution is set by the factory-calibrated accuracy of the internal RC oscillator, 1%, which is better than the accuracy of the film resistor + nasty X7R or similar cap you'd have to use in the 555 solution to squeeze under the price bar set by the µC solution. If you use a sub-1% cap to equal or exceed the accuracy of the µC, you blow both the BOM and board space budgets. The µC option also gives you the ability to null out individual pot errors with a LUT inside the chip, if accuracy was really important.

I like me some analog, but sometimes a digital solution really is better.
