DIGITAL TACHOMETER COUNTER
This circuit generates a readout for a digital tachometer. IC9 functions as a 3-digit LED display driver, counter, and latch. IC8 operates the common cathode LEDs, which are activated by transistors Q1, Q2, and Q3. Refer to page 268, Fig....
Tachometer circuit
This is a simple circuit that functions as a tachometer. It operates as a frequency-to-current converter, transforming the incoming signal into a proportional current to drive the meter. The deflection on the ammeter correlates directly with the frequency of the...
Bubble display proof of concept
Some time ago, a captivating water display showcased by Jeep at conventions caught attention. The design appeared straightforward, prompting the decision to create a similar project. Instead of utilizing falling water, the concept involves using air bubbles that rise in...
Game-scoring Display ScreenCircuit
The game-scoring display screen circuit diagram is depicted in the image above. The circuit consists of an add/subtract scoring input circuit, an add/subtract scoring circuit, a counting-decoding display circuit, and a reset circuit.
The game-scoring display circuit is designed to facilitate...
display and serial interfacing of
This hardware is designed to display the number of cars in a parking lot. The system utilizes a six-segment display; however, a single display is sufficient for the intended function. It employs the segment driver IC SN7447AN along with a...
tachometer circuit diagram
The system primarily consists of a permanent magnet disk, an integrated Hall sensor, a strobe gate, time base signal circuits, a power counting circuit, and a digital display circuit. The counting and digital display circuit utilizes the CMOS-LED digital display...
Pots water alarm circuit
The flowers in pots require watering, as relying solely on the observation of moist soil surfaces can be unreliable. To address this issue, a flower watering indicator has been developed. This circuit includes a field effect transistor (VT1), a second...
Digital Bike Tachometer Circuit Schematic Diagram
This digital DIY tachometer for bicycles utilizes two reed switches to gather speed information. The reed switches are positioned near the wheel rim, where permanent magnets, attached to the wheel spokes, pass by and activate the switches. The speed is...
5x7 DISPLAY
You must be able to recognise components such as capacitors, diodes, zeners, transistors and resistors to build a 5x7 Display project. This information is covered in our BASIC ELECTRONICS course and a complete set of circuit symbols can be found...
