Circuit Documentation

Summary of the Circuit

The circuit described by the provided inputs is a control system that utilizes a 5V relay to switch a load, which in this case appears to be a bulb. The relay is controlled by an LDR (Light Dependent Resistor) and a toggle switch. The power for the relay's coil and the LDR is provided by a 48V to 5V converter, which in turn is powered by a 12V battery. The circuit includes two bulbs that are powered directly by the 12V battery through a toggle switch. The LDR's digital output is connected to the relay's input, suggesting that the LDR may be used to trigger the relay based on light intensity.

Component List

5V Relay

• Pins: Normally Open, Common terminal, Normally Closed, In, GND, VCC
• Description: A relay is an electrically operated switch that allows you to control a high-power circuit with a low-power signal.

LDR (Light Dependent Resistor)

• Pins: A0, D0, GND, VCC
• Description: An LDR changes its resistance based on the ambient light level, typically used in light sensing applications.

48V to 5V Converter

• Pins: out+, out--, in+, in--
• Description: This component steps down the voltage from 48V to 5V to power low-voltage electronics.

Bulb

• Pins: GND, power
• Description: An electrical device that emits light when a current passes through it.

12V Battery (Small Size)

• Pins: VCC, GND
• Description: Provides the power source for the circuit.

Toggle Switch SPST (Single Pole Single Throw)

• Pins: L1, COM
• Description: A switch that can connect or disconnect the circuit at one contact point.
