Making Flasher, Timer, Oscillator Circuits Using a Single Chip A built-in oscillator stage in the IC 4060 chip makes it truly versatile and applicable for numerous different applications. It can be easily configured as an accurate timer, oscillator, flasher, clock generator, or sequential timer, and that's just the beginning of its usefulness.
Understanding Shunt-Wound DC Motors Shunt DC Motors operate on direct current. As such, the field windings and armature are connected in a parallel combination, and in electrical terminology a parallel combination is known as a shunt. This type of motor is a "shunt-wound" DC Motor and the type of winding is called a shunt winding.
IC 4013 Pin-Outs and Datasheet Explored This IC is basically made up of two D-type flip flop modules and set/reset asynchronous toggle inputs. As the name suggests, the IC is primarily used as a bistable for toggling the output stage of a particular circuit, and it is fundamentally incorporated in most electronic circuits.
