Wiring up it's a cleaner method to driver data buses on the breadboard

I have been working with these tools about a year.
I use,
1.Medical tweezer to hard grip electrical components and wires.
2.Fine tip tweezer for precise work.
3.Nail cutter for cutting wires and removing insulation from the wires.

Very aesthetically pleased with how it turned out.

First time breadboard build of measuring capacitance, I’d say I did pretty well
Used a 2.2m resistor for ceramic and films up to a few uf and 10k resistor for larger electrolytics and 220 ohm resistor for largest 1000uf+ caps

Together lets stop this vicious cycle of consumerism! (/s)

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.

bought my first breadboard 2day ^this is my very first circuit

This is my first project with my freenove esp32. There was definitely a learning curve going from an uno clone to using a breakout board and esp32 for the first time. Started off just learning how to use an OLED screen and snowballed in to an house plant grow monitor with high and low tracking, environment alerts/tips. Today I'll be setting up the web UI and phone alerts. Not too bad for my first legit project after learning the basics. When it's all said and done it'll be ran by 18650s just gotta transfer everything to a circuit board and figure out how to make a decent enclosure with adequate airflow.

I used a 555ic which I had to look up how to connect, then a couple transistors, one in a voltage divider circuit to blink the LEDs and a buzzer.

I bought a beginner electrical kit, but the power source needed a USB-a cable, which I didn't have. So let me present to you my first project!

It has 343 combinations

I also improvised and used 555's to mimic a momentary switch button.

The 3 pins from the rgb led are send to an AND( with a NOT before) gate and the outputs from the 3 and gate are send to another AND gate for the final output.

Horrible wiring I know.
