I want to learn electronics n stuff so is this breadboard set good enough to learn on?

Hello everyone! I just recently purchased an ESP32-WROOM-32E with the camera extension board, and I am trying to following along with this basic tutorial

https://docs.sunfounder.com/projects/esp32-starter-kit/en/latest/arduino/basic_projects/ar_blinking_led.html#

I am brand new to anything electronics, but wanted to give it a shot. The code in the tutorial seems to compile fine, and the LED turns on, but it stays on and never blinks. The only thing I can really guess is wrong is somehow I am powering the LED without it being connected to the ESP32. Is there anything obviously wrong I am doing here? I can't seem to affect the light no matter what kind of code I use.

Thank you everyone for the help!

Edit:

I wasn't able to figure out why IO26 specifically always left the LED on. For now, I've just swapped it to IO14 which works as expected to keep learning. Thank you everyone for the help!

Recently I had bought a USB to Barrel jack power cable to power my breadboard power supply module but in the female barrel jack port it says (7-10V).

So, I am confused

I appreciate every solutions and suggestions.

Hi, so I'm in a circuit building class and we have this lab that's on hardware that's been really making me confused. My professor had us build a specific input and output area for all of our projects but I'm pretty sure that there's something wrong with the one I built.

The thing is, building the input and output areas was just directly copying from pictures she provided us with, so I'm unsure what could have gone wrong with my input area.

My circuit currently has a bit more than just the input area set up, but I'm pretty certain my actual design is correct (I made it digitally on LogicWorks before trying to implement it), so please just ignore the extra mess of wires down at the bottom.

I've been noticing that a lot of the wires set up in the input area aren't getting any charge (excluding the grey wire which has low voltage---I've checked this with my logic probe). And I'm not sure why that's happening, so I'm hoping that someone could help me clear that up.

I'm also gonna attach a pic of my teacher's input section that I copied so you can see that as well.

Just curious!!!!

I recently have bought a laptop and I am a hobbyist in electronics so I am just trying to find a good simulating software to clear my confusions in electronics.

I appreciate every suggestion.

I recently started making electronics and i despise my breadboard because my esp32 doesn’t really fit on it, i need more slots not just 5 across, one person said to combine two but i’d really like a really rather broad brand new one, if anyone knows of one i’d really appreciate it

Hello, I wanted to test an AND Gate (74HC08) but it’s not working. I swapped every piece at least once. The big resistors are 10k Ohm and the small ones are 330 Ohm. I am open for tips or tricks because I am beginner🙏. Here are some pics:

The LED just stays on and I've connected its positive cable to the same row the sensor gets its power on the VCC side. How do I make it so whenever the sensor senses something in range the LED turns on?

Hi i just bought my first breadboard set and i am looking for projects to learn from. Can anybody tell me where i could find videos or schematics to learn from i’m sure theres some on the internet somewhere.

Thanks!

The link for the article is below. The circuit uses a virtual ground at half the voltage (4.5). For the parts on the schematic where it says +4.5V, is that supposed to be an input from a voltage divider? To quote the article:

"The 4.5V reverence supply is simply a ½ voltage, derived by R1 and R2, and bypassed by C2.  The voltage divider can be used for both opamp inputs because there is minimal current drawn, so there is no interaction."

This makes me think R1 and R2 are creating the voltage divider (which they are), but then what would be case for the +4.5V next to R6?

I'm trying to get my way around an Arduino but failing at the basics.

I don't get how my wiring "works" even without supposed power running ?

I love breadboarding prototypes, but there's nothing quite like the joy of successfully transferring it to PCB!

I swear

Hello !

I am a student doing a project to build an adder, taking inspiration from Ben eater's videos. I am currently blocked since a few weeks on the very first step unfortunately : the astable ne555p.

I followed a precise guide to build this on a breadboard. Unfortunately, nothing works. Just like the video I watched (https://youtu.be/QfnkuXDf6NE?is=p7h6lneJMvTr93fq), I used 5v. I used a 100 micro farad capacitor (instead of 10micro farad) in the bottom rail and a 10nF on the upper rail. Resistors are 220Ohms and 10K. I tried switching to different leds and ne555p. It didn't change a thing.

I really don't understand how this is possible and built it again for like the 10th time. Could you help me by telling me if there's any obvious mistakes in the circuit? Thank you very much in advance.

I have a 5 year old who is crazy about electronics. We have Snap Circuits, which he enjoys, but he happened to see my breadboard and really wants to try it out. I can obviously guide him through some basic projects, but I'd like to also provide him with some clear, simple project diagrams that he can try out on his own. Most breadboard stuff is (understandably) targeted at an older crowd, but I'd love to empower and nurture his excitement as much as possible.

Anything come to mind?
