| - | Another method is to just have a timer waiting a set time for the capacitor to charge. This can be useful if that fits the application better, but it's less efficient than the methods above, as you need some power to run the timer. I tried this with a 555 IC, but the power coming from the solar cell was insufficient to run the timing chip. | + | Another method is to just have a timer waiting a set time for the capacitor to charge.
