Make More Electronics 1–5
I’m really new to electronics and wanted to learn more about wiring up circuits to create my own prototypes, so I bought Make More Electronics. I wanted to share some things I found unintuitive so that others can break through the same issues, hold myself accountable, and inspire others to start!
- Do not buy gigantic alligator clips — they do not hold small wires.
- 9V batteries are easier to use than setting up voltage regulators.
- How to use a breadboard. You want to set your pins vertically — each horizontal row is a different connection. Additionally, the middle is a gap, so the connection doesn’t go to the other side unless you intentionally make it that way.
- 13.7 microamps because I switched GRND and 5V on the trimmer.
- Check your power source to make sure it’s tight enough. Had so much trouble figuring out why my circuit was incorrect for the longest time.
- Took out 100 resistor to get circuit to work.
- When the light was too bright, the circuit shut off entirely.
- Multimeters when put in mV mode will fluctuate a lot.
- For some reason(haven’t figured out why), poking at ground with ground from my multimeter retriggered the circuit.
- My bug for the longest time: the green wire you see above wasn’t clamped tightly enough.
- Couldn’t find a speaker that took in >50 ohms, so I had one that took in ~5. Maybe that’s why I get strange noises/it’s not working properly?
Nothing really to say. Measurement-heavy.
This one was really fun!
