Touch Counter circuit | Next Electronics

S1 is a power switch. U2 drives counter U3 by producing a pulse when S2 is depressed. U4 and DISP1 read the count of counter IC U3. S3 is a reset to zero switch. The counter is a basic one-digit...

Touch Sensor Circuit

This project utilizes two wires, one red and one blue, which function as touch sensor wires. When a person touches both wires, the circuit closes, allowing current to flow and illuminate the LED. A 9-volt battery or an external power...

Seven-7-Segment Counter Circuit with LED Display-Diagram and Schematic

A simple seven-segment counter circuit with an LED display. This counter circuit diagram is designed using the IC CD 4033 as a counter, a 555 Timer IC, and a seven-segment LED display LT 543. The seven-segment counter circuit utilizes the CD...

1 Kw flip-flop flasher circuit

This application involves a static switch circuit where the control logic is implemented using a flip-flop, which is driven by a unijunction transistor. The flashing rate of the circuit can be adjusted, ranging from approximately 0.1 seconds to a 10-second...

Flip-Flop Debouncer Switch

This circuit utilizes a 74HC74 flip-flop, although any CMOS variant of this component can be employed. IC1A functions as a true/complement buffer. Resistors R1 and R2 ensure that IC1A exits the reset state prior to the clock edge occurrence. Resistor...

RING OF 7 COUNTER

Uses surface-barrier transistors in an arrangement where a pattern of four on stages is stepped along a ring, allowing the maximum number of stages in the ring to be significantly higher than in conventional rings. -W. Carlson, Ring Counter has...

Logic gate using current source and diodes

The voltage at the anode and cathode of the diodes is checked to determine whether they are conducting. There is confusion regarding the current source and how to determine the state of the diodes for input combinations (00, 01, 10,...

Debounced Counter Made From Off-The-Shelf Chips

The true utility of the SR latch is evident during transitions of the input switch. Assume that the input switch is of the break-before-make type and starts in the up position. When the switch is up, the input values are...
