Clones of the popular Arduino Uno are now so cheap, it's difficult to save money by building your own. But the knowledge gained from assembling an Arduino from individual parts, makes the exercise well worthwhile.

Tem um arduíno que é muitíssimo barato . Seu nome é lgt8f328p e ele é muito versátil e tem as mesmas utilidades de um arduíno . Mas é legal fazer um .
So it begs the questio, what is all the other stuff on an arduino board for?
Hello… Good video and very instructive.
I did everything indicated in your video, and it works, but sometimes an error appears:
"avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x8c"
One step that you don't show in your video is when you are programming the Arduino IDE: Card, COM, but you don't see that you choose the Programmer.
What programmer do you use?
if i do this, would it be possible to run the program without the usb to serial after loading it?
would i just need to connect a power source to the chip?
remember you could use your homemade clone to programme arduino chips for standalone purposes. most arduinos i've seen ,the chips are soldered onto the board yours are pluggable
Thank you Julian! This tutorial was a huge help!
USB to ttl converter, eh? I'll have to dig mine out. I bought that thing in like 2017.
Very weird! I have a rip off Arduino and it has exactly everything a genuine one has. the only difference is that this one has a different brand called UNIROI, It even sounds like Arduino in a way, and it preforms just like on was well. I can't believe they didn't get sued by Arduino.
Nice buil!
white is more commonly positive, blue is more commonly negative
Brilliant. From England 🇬🇧
It is cheaper because you can buy multiple ATmega328P chips and use this circuit only for programing. You only need to buy the USB to TTL converter once after that you can build infinite Arduinos with it.
If I am not mistaken the USB to Serial converter is only needed for initial programing. it could be removed when the device is deployed, correct?
Great video! To be pure minimalist, no LED/Resistor and the USB to Serial Adapter would be part of your special programming cable (not part of the board).
You can make a simple PCB, the Microcontroller, the Crystal, 3 Capacitors, A 4.5V Battery Clip, a Diode, and a Female Header Connector that you plug the USB to Serial Adapter into to program/comms and then remove it (freeing up 2 more I/O if you need them but no comms). I would suggest a 1uF Capacitor across the VCC and GND pins of the microcontroller for added decoupling of the power pins. To save even more money, you could learn the complicated process to install the Bootloader yourself.
I think I am going to add this project to the Summer STEM class I teach – I try to save my students every penny as they pay for project materials, but I teach the class for free (8 hours a day, 5 days a week, 8 weeks over the Summer).
Great explanation, with a clear and comprehensible language. Very appreciated when you see the tons of videos made by people who do not articulate and talk at the speed of a formula 1.
what is the value for ceramic cap is it 20pF or 200pF
If it is okay with you, I will make an instructable based on this…
currently rigging an old 3d printer board and re programming it to control a claw machine over discord
I'm happy with that.
