Simple one shot Touch Switch using IC4011

Today we lets to play simple digital circuit. It is an One shot touch switch control. I use IC-4011 digital cmos is base of circuit. It is set form as flip-flops. The Logic “HI” at output when Your finger touch pad and is time delay for 3 second. Which we can determined this pulse time delay (one shot) by C1-electrolytic capacitor of 47uF (micro farad). After that touching the plate connected, so well pulse output. Detail more Please read in this image circuit and see video below.

In this circuit not have LED display, thus I add them in breadboard, so that show working of this circuit. we use 1k-resistor is connected with series it to control proper current flow it.
