What is IC 4017

IC-4017 IC-4017 CMOS-Decade counter/divider When we build the 10 LEDs running light for hobby. Often use IC-4017 CMOS-IC. This really neat chip contains a counter and a decoder circuit, that can show a single output pin for each count from 0 to 9. And also use to build all kinds of timer, LED sequencers and controllers circuits. Look at the Figure below is block diagram of inside IC-4017. The IC 4017 counts with 5 D-type flip-flops. Decoding and control is by 16 inverters and 15 gates. block diagram inside CD4017-IC The importance Pins look at table below.     1.) Pin 16 is positive power supply and pin 8 is a ground. The power supply range of 3 volts to 16 volts and Maximum power supply voltage at pin 1 must not much than 18 volts. 2.) Pin 13 is Clock enabled pins to controls the clock. When it is “0” logic, the clock is enabled and the counter advances one count for each clock pulse. When “1” logic, the clock input is stop,

How MCB works, and what's inside it? | MCB कैसे काम करता है? MCB के अंदर क्या होता है   MCB s or Miniature Circuit Breakers are electromechanical devices which protect an electrical circuit from an overcurrent. The overcurrent, in an electrical circuit, may result from short circuit, overload or faulty design. An MCB is a better alternative to a Fuse since it does not require replacement once an overload is detected. Unlike fuse, an MCB can be easily reset and thus offers improved operational safety and greater convenience without incurring large operating cost.   Our Youtube Channel The principal of operation is simple. An MCB functions by interrupting the continuity of electrical flow through the circuit once a fault is detected. In simple terms MCB is a switch which automatically turns off when the current flowing through it passes the maximum allowable limit. Generally MCB are designed to protect against over current and over temperature faults (over heating).
