Frank Donald February 15, 4 Comments. Electronic Locks. Electronic Locks are highly useful to protect our possession and it was widely used in all places. The demand for Electronic locks is high since it offer high security and easy to handle rather than the mechanical locks. Most of the E-locks in the market are cost more and not everyone could afford buying these locks. The circuit above can be a best solution for those who want to build an effective and low cost Electronic lock.

A clock pulse flow to C clock pin , will store the data at the D input. Connect clock and a both Q output to make a toggle flip-flop for counting. For example use them: 1HZ Standard digital clock.
The importance Pins look at the table below. Pin 14 is a positive power supply and pin 7 is a ground. The power supply range of 3 volts to 16 volts and Maximum supply voltage at pin 14 must not much than 18 volts.
See in the truth table of The first column in the truth table is for the clock input. They have three states are 1.
The rising edge of a clock pulse. CD at Amazon. When we enter a signal with a high frequency to the input of IC It will divide the frequency by two. For example, you enter 1KHz frequency. Then, the output is Hz in the same waveform. I always try to make Electronics Learning Easy. This site uses Akismet to reduce spam. Learn how your comment data is processed.

Understanding IC 4013 Pin-Outs and Specifications - Datasheet and Application Circuits Explained
The IC incorporates two sets of identical, discrete data-type or D-type flip flop modules. D-type flip flops refer to circuits which may have a couple of outputs that change or toggle states in response to triggers applied at the input terminals. Complementary Ouputs Pins 1, 2, and 13, 12 : The sets of outputs change states when operated in the bistable mode or while setting and resetting the IC, always producing opposite logic levels at any instant. For other configurations this input is terminated to any of the logic levels, i. Clock Input Pins 3 and 11 : This input is used for receiving clock signals which are normally in the form of square waves.
