Relay control circuit
The motor winding is configured with delta transposition capacitance, designated as cl-C-3G. It operates as a DC LAN speed generator and is associated with a three-phase asynchronous motor, which is coaxially connected through a field winding powered by a 10V...
light dependent blinker using ldr and cd4093
This is a simple experiment involving a Light Dependent Resistor (LDR) and a CD4093 integrated circuit. It modifies a previous dark sensor project that utilized two transistors. In this configuration, when light falling on the LDR is obstructed, the circuit...
low current relay circuit
This circuit design for a low current relay is intended for use in battery-operated electronic devices, with an operating current in microamperes (µA). It utilizes a bistable relay and additional components to enable the relay to function similarly to a...
Relay Coil Energy Saver
Some relays may become warm if they remain energized for an extended period. The circuit presented here will actuate the relay as before but will reduce the hold current through the relay coil by approximately 50%, significantly decreasing heat dissipation...
Arduino Light Sensors
A project is underway to determine the number of sun hours available at a specific location and to track this data over time as part of solar power installation design. The concept involves utilizing a light detector exposed to sunlight...
No inductive analog relay circuit
The relay illustrated in the figure operates based on non-inductive analog circuit theory. Its working principle involves a 220V power supply connected to a load (RL), resistors (R1, R3, R6), diodes (D1 to D8), and a zener diode (ZD1). Transistors...
GS500 Horn
A relay is an electrically operated switch that utilizes a coil to create magnetism, which closes the contacts of the switch. In automotive applications, a 12V signal through the coil allows 12V to flow through the switch contacts. The advantage...
Light Controlled Relays
The first circuit energizes the relay when the light rises above the preset level. The second circuit energizes the relay when the light falls below the preset level. The two circuits are practically identical. The only difference between them is...
dark detector led ldr
This project involves a simple dark detector LED circuit. In a previous discussion, a light-activated LED circuit was presented. By rearranging the positions of the resistors and the Light Dependent Resistor (LDR), the circuit has been transformed into a dark...
