SCHEMATIC DIAGRAM

As you can see this circuit is very simple but very useful for our projects there you can see the electronic components that were used and designed in the EASYEDA software and it works very well

FUNCTIONING

As we already know, in a pedestrian traffic light we have 2 images, the first is a green moving one saying that you can cross the track and the second is a stop image, an immobile image so that they cannot cross since the cars are moving knowing how it works is very basic and understandable.

This project is powered with 12VDC since it is in an arrangement of 5 leds in series and we have 12 series of red smd for a better and ultra-bright visualization.

We can test it directly with a DC 12V source or also take it to the programming in the next step we will see a little code to test it and see if it works correctly we can program it using arduino or another microcontroller.

when we give a 5v signal to our ARD and GND pin it will activate my image and it will turn on when we give it a low pulse or 0V my image will be off everything depends on a pulse whether it is positive or negative

ARDUINO CODE

void loop() {
 digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
 delay(5000);            // wait 5 seconds
 digitalWrite(LED_BUILTIN, LOW);  // turn the LED off by making the voltage LOW
 delay(1000);            // wait for a second
}

EASYEDA

Once the project is finished with all the respective tests, we carry out the PCB design and we will obtain the routed tracks and the 3D image of how our finished PCB would look.

JLCPCB

Once the pcb is designed, we will send our friends from JLCPCB to manufacture our PCB.
