I delt so dumb after this 😭😭

[Chidera || Midrex @Midrex_0]

A microcontroller can't drive a motor directly — too little current.

But it can trigger a relay, and the relay switches the big stuff. Two circuits, one box.

Day 11, learning Mechatronics + AI from zero. #mechatronics #buildinginpublic

[Chidera || Midrex @Midrex_0]

A DC motor converts electrical energy into rotational motion.

Simple concept, but it's the component behind almost every physical robotics build.

@davestack_dev Wanted to build what I had in my imagination and got started

[Chidera || Midrex @Midrex_0]

The battery is the pushing force. Connect it across a load — a lamp, LED, or motor — and electrons flow.

Inside: chemical energy becomes electrical energy the moment a circuit closes.

[Chidera || Midrex @Midrex_0]

An inductor is a coil that stores energy in a magnetic field, not charge like a capacitor.

Picture a water wheel in a pipe — it resists sudden change in flow. That's what an inductor does to current.

Diodes let current flow one way and block it the other.

Small rule, but it's the reason rectifiers and LEDs work at all.

Day 7 of learning Mechatronics + AI from zero — one week in. #mechatronics #buildinginpublic

[Chidera || Midrex @Midrex_0]

Day 6: Review Day.

No new topic — going back over electricity basics, voltage, current, Ohm's Law, series/parallel circuits.

Speed means nothing if it doesn't stick. #mechatronics #buildinginpublic

[Chidera || Midrex @Midrex_0]

@itsvishaltwt Claude is more addictive than Netflix
Y'all can agree with me

[Chidera || Midrex @Midrex_0]

Series circuits share current. Parallel circuits share voltage.

Sounds simple until you're the one wiring it and everything short-circuits anyway.

Day 4 of learning Mechatronics + AI, from zero.

Today: Ohm's Law — voltage, current, and resistance, and how they relate.

Four days in, still consistent. #mechatronics #buildinginpublic

What is your favorite programming language right now?

[Chidera || Midrex @Midrex_0]

Honestly in my take, no one can matter Hardware without understanding the basics

[Chidera || Midrex @Midrex_0]

Day 3 of learning Mechatronics + AI, from zero.

Today: electrical current — AC vs DC, fuses, circuit breakers.

Three days in, still consistent. #mechatronics #buildinginpublic

[Chidera || Midrex @Midrex_0]

@monarch_0I @grok Chat gpt is programmed to agree with you at all times 😂 . You could tell it that you kill someone and if it's wrong , bro would be like .
"It's perfectly alright 😊,
You thinking that it's weong justifies that you didn't mean to kill the person."

[Chidera || Midrex @Midrex_0]

Day 2 of learning Mechatronics + AI, from zero.

Today: voltage — what it is, how it moves through a circuit.

No light indoors so I filmed outside 🤧 Still not 100%, still posting. #mechatronics #buildinginpublic

[Chidera || Midrex @Midrex_0]

Day 1 of learning Mechatronics + AI, from zero.

Today: how electricity actually works — voltage, magnetic fields, resistors.

Recorded this while not feeling well 🤧 but Day 1 doesn't get skipped. 59 more to go. #mechatronics #buildinginpublic
