Tinkering with electronics...


With nothing important to do today, I built a simple 555 astable circuit which flashes an LED. I replaced the 220k resistor (R2) with an LDR. This way, I got an astable which changes frequency in response to light intensity. Fun. :)

Simple enough schematics - a dummy like this might just be able to do this as well - really fun :) PE
