-15 Volt output regulated power supply circuit Schematic Diagram

Time delays ranging from 0 milliseconds to over three minutes can be achieved with this circuit without the need for tantalum or electrolytic capacitors. The timing interval begins when power is applied to the circuit. At the conclusion of...

The electret microphone operates with a current of 200 µA, which varies by ±3 µA in response to sound waves. This variation results in a voltage of 2V across resistor R1 and 4V across the microphone. As sound waves...

The Arduino Uno has adequate memory and ports, but efficient programming is necessary to store settings in memory. The Mega version offers increased memory and ports. The Shako valve operates on 24 volts DC; however, 12 volts is preferred...

Control 30 incandescent light bulbs with an Arduino Uno on three channels (10 bulbs per channel in parallel). Previous experience involved using an Arduino to control red, green, and blue LEDs with a simple schematic that included three transistors....

A simple proximity detector electronic project can be designed using this schematic circuit. This project utilizes a tone decoder integrated circuit (NE567) that provides a signal with a frequency of approximately 100 kHz. When an object is placed near...

This design presents an innovative approach to the Joule Thief (JT) circuit typically utilized in garden lights. Instead of directly charging a 1.2V battery from the solar cell and converting the power to operate a 3-volt LED, this circuit...
