Disclaimer: I'm a noob.

I have the following schematic (updated as per @Transistor):

enter image description here

enter image description here

enter image description here

I had first tried this out on my breadboard. It worked fine. From what I read online, this was two capacitors set up in parallel.

When I do the setup on a PCB prototype board, it short circuits (I'm assuming it is a short circuit because the lights of my Arduino Uno go off.)

Is this enough information for someone to be able to tell me what I'm doing wrong? I can post a picture of what the setup actually looks like if needed.

    \$\begingroup\$ Hi, a picture (photo) of both sides of the board might be helpful here. \$\endgroup\$

  • \$\begingroup\$ It is very difficult to see, where there could be a short circuit. No offense, but I recommend to discard this board and do some soldering exercises first. It's been a while since I have seen such soldering joints. I've seen worse, but not many. \$\endgroup\$

There isn't enough information in the question to answer fully but your schematic is not correct.

If you can clarify in your question what is going on we will help further.

  • \$\begingroup\$ What kind of info so you need? When I complete the circuit, the LED lights of my Arduino go off. The servo doesn't turn on. \$\endgroup\$

    \$\begingroup\$ @Yousuf, I'm probably many thousands of kilometers away from you so I can't see what you have done wrong. Don't you think a photo would help? Add one or more into your question using the edit link below it. \$\endgroup\$

Both the 5v and the GND are connected to the same pin of the capacitor. Since there is no resistance in this path, your circuit ends up shorting to ground.

I've redrawn your circuit with more legibility here.

  • \$\begingroup\$ Actually, it's not like that. I have the 5v to the positive side and the ground to the negative side of the capacitors. \$\endgroup\$

  • \$\begingroup\$ @Yousuf That's how your initial schematic was. I answered the question before you updated the schematic. \$\endgroup\$ Commented May 2, 2020 at 3:08
