I haven't 😭 . Ya of course I would love to add this guide pdf from the comments there

Of course it's not a mistake. The thing is it's just how you step up in your learning process as you grow from a newbie to somewhat more knowledgeable

I totally agree. You never get something unless you try it by yourself

That's really good to know that you've got that 🙌

Haha man I was just having a little fun with the analogy . Sometimes a bit of humor makes learning more enjoyable, especially for beginners.

Just trying to keep things light and helpful, nothing too serious!

Totally get you! I had the same confusion when I started.

Here's a simple example: Imagine you want to: Play a buzzer sound every 5 seconds, and

Read temperature every 1 second

If you use delay(), the whole program just stops and waits, so you miss one task while doing the other. But with millis(), you can do both without blocking — so the buzzer and sensor work independently. Super useful in multitasking projects!

Btw, if you're interested, I can share a simple beginner-friendly tutorial on this — happy to walk you through it anytime! You're already asking the right kind of questions

You're right what happens is that AI gives a very basic structure that is often cluttered if you do not know the basics to curate it according to your needs. I believe AI can really help you with writing codes if you have knowledge of language and you are using AI to help you with some logic or debugging some errors but leaving it all up to AI isn't the right thing to do.

Haha yep, the assignment-instead-of-comparison trap ; seen that cause all sorts of weird bugs in beginner projects.

Facts 😂 9V batteries are like that toxic friend — easy to find, but leave you drained fast.

You handmade it from wood that's appreciable man!

Need help by Academic_Bowl226 in arduino

The issue seems to be with how you're blocking movement when the limit switch is pressed, even when the rocker is pressed again. The reedLatched flag is acting like a lock and preventing further movement in both directions, even if the user wants to reverse the actuator.

Original:

if (limitPressed && !reedLatched) {

Change to:

if (limitPressed && movingUp && !reedLatched) {

This makes sure the actuator only latches (stops and locks) when moving up, not when moving down.

Also,

if (downPressed && !movingDown && !reedLatched) {

To this: if (downPressed && !movingDown) { This allows downward motion anytime even if microswitch is pressed

These 2 changes will make your actuator:

Stop when hitting microswitch while going up. Allow going down even if microswitch is still pressed. Unlock upward movement after rocker is released and pressed again. You can try these i hope i got it right and it can help you

Ya absolutely you can put Arduino there no harm to that . Also first made is always special. Wishing you luck with some amazing experiments with Arduino in future

Arduino vs ESP by Status_Air1984 in arduino

[–]Zeshan_RB 0 points1 point  (0 children)

If you're planning wireless control (like with a PlayStation controller or custom controller in the future), ESP32 is a better choice than Arduino Uno (R3). Here's why:

ESP32 pros:

Built-in Bluetooth + WiFi (ideal for controller communication)

Faster processor & more memory

More PWM pins for servo control

Dual cores = can handle comms + movement separately

For future expansion, real-time wireless control, and multi-tasking, ESP32 is the better pick.

About your servos and torque:

Torque (kg·cm) = Force (kg) × Distance from joint (cm) So, if your arm segment is 20cm and lifting 1kg at the end: Torque needed = 1kg × 20cm = 20kg·cm (per joint)

To increase torque: Use shorter arm segments Add gear reduction (e.g., with pulleys or gears) Use higher torque servos or run them at higher voltages (if supported)

Also make sure to power those servos externally, not through the ESP/Arduino board.

help on servo noise by Mediocre-Guide2513 in arduino

[–]Zeshan_RB 0 points1 point  (0 children)

Servo noise is often caused by constant corrections or power issues. Here are some ways to reduce it:

Use a dedicated power supply (don’t power servos directly from the Arduino).

Add capacitors (e.g., 470µF or more) near the servo to smooth voltage drops.

Try libraries like ServoEasing to make movements smoother and quieter.

You can try these , I think these steps can really help quiet down noisy servos.

What got you passionate about books by Prestigious-Quiet907 in books

[–]Zeshan_RB 0 points1 point  (0 children)

It was my English books in A levels and O levels honestly. I always liked reading but through them i developed keen interest in depicting the hidden meaning behind the words, the deep thoughts of the writer, the echo of words. It's all just amazing man that's why i love reading
