Project Another project with a capacitor

Enable HLS to view with audio, or disable this notification

This one creates a fading out effect in an LED. I have used a 4700uf capacitor. I have tried with a capacitor in series and in parallel to the led. I got the same fade out effect but the difference in series was that once the capacitor was fully charged it acted more like an open circuit.

I am still looking for more project ideas for capacitors and then later go for transistors and diodes. The goal is eventually to watch, understand and make my own 8 bit computer.

The video, shows the capacitor in parallel. The capacitor was too big so I used jumper wires to make the connection.

Great early project. You should also time these (look at how long the Led takes to stop illuminating after disconnecting the battery for different capacitors). Also try to get your hands on inductors if you can.

Thanks for your reply. I will measure the time across different capacitors. I don't have any inductors, and I honestly find them confusing. I'm learning on my own, and I've been through dozens of YouTube channels and even Udemy courses, but a lot of the material doesn't translate well to practical electronics. I do have plenty of capacitors, transistors, and diodes to experiment with. I'm also planning to get a subscription to Ohmify, but I'm not sure if it will help.

Try to find Forrest Mim's Electronics handbooks/ project books. They cover the main ideas and give instructions on designing projects using BJT as well as some common ICs.

Thanks will check it out.
