I want to build some things with microcontrollers. What kind

>>1098725
Clock?

Depends on what you're building.

What are you building?

>>1098725
What do you mean exactly?
Programming could be a bitch, depends on how professional and efficient you want the program on the mcu to be.
One of the easiest ways is to program everything in arduino for instance, but if you want to have more control over everything in the chip or/and run more effecient programs you might want to switch to AVR programming or low level C.
Also for some applications you want to use a PLC instead of a MCU.

>>1098725
You are going to spent 53637h on reading documentation. And it's sometimes really hard without a debugger or at least a working usart.

>>1098725
The atmega128/328 used by Arduino are fairly easy when it comes to nailing the basics. You might want to spring for an arduino board that you can use to program the microcontroller; Usb to serial programmers have varying levels of documentation whereas arduino is thouroughly documented.

>>1098725
im doing this right now. learning C sucks

try to pick components that are popular so they have good support and proper libraries

>>1098728
Bane?

>>1098725
/diy suspects you won't actually do anything or will need excessive handholding

>>1098796
I've built shit before, but only simple electrical/mechanical things. A pathfinding robot, a tiny rocket, an ornithopter. I need no handholding; I know how to use the internet. I've just never worked with these before.

>>1098728
>>1098731
Yeah I literally just need something that oscillates from fast to crazy fast depending on, I dunno, how far I turn a knob. No more complexity than that.

>>1098768
>>1098732
Thank you senpais.

>>1098873
>Yeah I literally just need something that oscillates from fast to crazy fast depending on, I dunno, how far I turn a knob. No more complexity than that.

You don't need a microcontroller for that. In fact, a microcontroller would be a very bad way to approach that because of overhead.

How fast is "fast" and how fast is "crazy fast"? What kind of signal? How accurate does it need to be?

>>1098873
you can maybe do this with a 555 timer with potentiometer hooked up to modulate the speed depending on what "fast" and "crazy fast" means to you

>>1098880
Fast would be 4kHz. Crazy fast would be as fast as I can get it to oscillate by any conceivable physical limits.

>>1098884
Ooh, this setup looks much easier to put together.

Are you attempting to hide a sex toy thread as a microcontroller thread?

Anyone play shenzhen i/o?
how close is this to the real thing? Can I learn anything from this game?

Took me about a year (not actual man hours) of research to go from fucking around with Arduino to designing my own board. So if you know almost nothing about computer engineering and spend about 2-4 hours per week on it maybe a year?

>>1098873

Ohhh, you want to make a vibrator. They sell those on Amazon or at your local adult toy store.

>>1098905
;)

>>1098994
I made a vibrator when I was 12 from a plastic test tube, a motor, a fishing weight, and some tape/wires/glue. Just go to Amazon and buy a real one. DIY sex toys suck.

What software did you use?

Why don't you kindly tell us what you're trying to do because obviously you don't know what you're trying to do.

Double check connections and try again, or use -F to override

Go away Ahmed, this isn't the right place for you

>>1099162
Thou hast learned true wisdom

>>1099162
I had some avrdude error shit once. Turned out it was because I was using pins 0 and 1 for MIDI stuff and this confused the USB thing on upload.

It was fixed by disconnecting the input pin while I compiled but I was going mad before I knew what was causing it.

Couldn't get my prototype working the first go around. Turns out I needed the reset to go to 5V on a resistor. Took me hours to figure out.

SHORTS?!

>>1099487

I'm afraid I do not get the reference famalam.

>>1099480

looks like you read a Make magazine and fell for every meme

>>1099488
Ahh no worries, thought you might be a friend of mine who is also doing a nixie clock project for himself and we have an in joke involving shouting the word 'shorts'.

What is a make magazine and do they have nixie clocks, especially ones you design yourself?

Also, where is your home made electronics that you designed and programmed yourself?

>>1099491

Ah, I see. No I couldn't be that person because I have no friends.

You made a robot hand? What microcontroller does it run?

>>1099504
Not him, but I once did a robot hand for disabled people, using PIC as the microcontroller, want to see it?

>>1098873
battery -> knob -> motor with a weight on it

don't need the microcontroller just put it up your butt

>>1098935
It's far more simplified

>>1099530
Want to see you being wanked off by a robot? No thanks m8.

>>1098984
Could swear I've seen the schematic for that PCB before when I was considering making a nixie (still am, just never any time).
