Design with 5v DC Power Supply in Cirkit DesignerThe 5V DC Power Supply is a device designed to convert AC voltage from the mains into a stable 5V DC output. This component is widely used in powering electronic circuits, microcontrollers, sensors, and other low-voltage devices. Its compact design and reliable performance make it an essential component in various applications, including prototyping, embedded systems, and consumer electronics.
This circuit is a 12V to 5V regulated power supply with an LED indicator. It uses a 5408 diode for reverse polarity protection, an LM340T5 7805 voltage regulator to step down the voltage to 5V, and a push switch to control the LED indicator. The circuit also includes capacitors for filtering and a resistor to limit the current through the LED.

This circuit consists of two 5V 5A power supplies connected to an AC wall plug point, providing DC output through a 12-way connector. The ground connections from both power supplies are interconnected and also connected to the ground pins of two toggle switches. The DC outputs from the power supplies are separately connected to different pins on the 12-way connector, with each power supply output being switchable via one of the toggle switches.

The 5V DC Power Supply can be used to power an Arduino UNO via its 5V pin. Below is an example of how to connect it:
// Example code to blink an LED using an Arduino UNO powered by a 5V DC Power Supply
const int ledPin = 13; // Pin connected to the onboard LED
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
| Issue | Possible Cause | Solution |
|---|---|---|
| No output voltage | Loose or incorrect AC input connections | Check and secure the AC input connections. |
| Output voltage is not 5V | Overload or faulty power supply | Reduce the load or replace the power supply. |
| Power supply overheats | Insufficient ventilation or overload | Ensure proper ventilation and reduce the load. |
| Circuit not working after connection | Incorrect polarity or loose connections | Verify polarity and secure all connections. |
