Divide-circuit
An input signal drives both SN74 D-type flip-flops, which are positive edge-triggered devices. A low-to-high input signal transition triggers the A flip-flop, while a high-to-low input signal transition triggers the B flip-flop via the SN7404 inverter. Either flip-flop in the...
Electronic counter
Simple counting can be performed by anyone, but counting over large intervals can be tedious and prone to errors. A previously published project, the Digital Counter, serves as a foundation for this electronics counter, which is the second project in...
12V 5MHz COUNTER
The portable counter is designed with low-power logic to minimize battery drain while maintaining good performance. Since most of the milliwatt power drain is consumed by the digital readout, the circuit blanks the LED display when there is no input...
1-20 minutes a timing circuit
The system operates between 10 minutes to 2 hours, featuring a 100-line bell controlled by a multi-gear stick labeled S2 41f. The integrated circuit (IC) functions as a self-excited multivibrator. The device can manage binary pulses ranging from 3 to...
freeze protector circuit
This is a simple freeze protector circuit diagram, also known as a timing circuit. It serves as a hobby project for beginners. This circuit can automatically operate any device after a fixed time once AC power supply is restored. The...
Flip-Flop Using CMOS NAND Gates
Using just two NAND or inverter gates, it is possible to build a D-type (or toggle) flip-flop with a push-button input. At power-up, the output of gate N2 is at a logical 1, ensuring that transistor T2 is switched off....
DIVIDE BY ODD NUMBER COUNTER
This circuit symmetrically divides an input by virtually any odd number. The circuit contains n+l/2 clocks twice to achieve the desired divisor. By selecting the proper n, which is the decoded output of the 74LS161 counter, divisors from 3 to...
Frequency Divider circuit
This is a classic frequency divider by two, implemented using a T-flip flop circuit, specifically with IC1 [4011]. In this circuit, the frequency from the network, after limiting the negative half-period of the sine wave and transforming it into a...
Odd-number-counter-divider
This circuit, illustrated symmetrically, divides an input by virtually any odd number. The circuit counts n + 1/2 clocks twice to achieve the desired divisor. By selecting the appropriate n, which is the decoded output of the LS161 counter, divisors...
