“This is a robot that lip-synching to the music and the voice . It responds with sound hit the keyboard . Please put in the vicinity of the radio and speaker . Figure to be lip-synching to the music is very cute .”

Dark Sensitive Switch LED Light

“Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment …

Comparator - Night Light

In the circuit of this article we will build a voltage comparator using an integrated chip called LM393. The LM393 is a dual difference comparator. This means that you have two independent voltage comparators. The circuit compares the input voltages …
