I need help verifying code

A friend of mine works with a lot of different devices and stuff, but he is not a programmer, he asked me this: "create arduino code for 3 thyristor regulators (each in a different phase) that need to be controlled with one common control signal? I have a link where there is code for one phase but I need 3 phases at the same time. I drew a circuit - it should work. Control could be either from an analog input with a potentiometer, or from a digital one with an encoder. " I'm a programmer, but I know nothing about electronics, circuits or anything of that sort, and I know very little C++, never worked with arduino before either. I read a bit on this topic but I am unsure about how much I picked up as it's a quite difficult and vast topic it seems like. Using AI I managed to get this, the code is pretty much all AI written, the question is, does this seem right? I have no real way of verifying this quickly either, as we are in different countries at the moment, so it would take a lot of time to know what results this gives. ...

help with distance gauging proximity meter thingamabob

so I'm making this thing that displays the distance of an object away from an HCSRO4 using 9 leds working as essentially a proximity counter. the closer the object is, the more LEDs light up (1 LED lights up at distance of 9cm, 2 at a distance of 8cm, 3 at 7cm..), but I'm having some problems. basically, either the LEDs flicker on and off randomly at random brightnesses, or just don't turn on at all, and i can't seem to figure out what's wrong. here's the code: #define TRIG_PIN 13...

Arduino Serial buffer overflowing/overwriten

Hi all, I'm new to arduino's technical stuff. I want to make a c++ program(app) that can take in files, then convert it into smaller chunks os bytes and send it to an arduino nano over the serial com ports and stuff over a cable. The arduino nano will then send it over nrf2l01 to another arduino that will be connected to another computer running another c++ program that will reconstruct all the byte chunks into the file. currently, my question is, how do I make sure that my arduino nano's serial buffer will not overflow and lose data? Also how do I make a windows explorer "select file thing" simply (for the c++ app)? Thank you for your time!...

What is the best way to improve at coding?

So right now I lack the ability to do pretty basic logical coding stuff with leds and stuff. What is the best way to get the basics of coding down? Should I get a book or something?...

Darn millis()

So I'm trying to make a code using millis(). When a button is pressed and held, a led stars blinking, when released the led stops. Im having a problem where the code isn't reading the button instantly, so there is the same delay, as the led blinking delay in my button reading....

Could anyone help me out with this issue? I can't seem to get SPI_DT_SPEC_GET arguments correct. when I hover over the macro it says identifier "__device_dts_ord_DT_N_S_soc_S_peripheral_40000000_S_spi_4a000_BUS_ORD" is undefined but i check the compiled devicetree and the overlay is applied correctly. using nRF54L15 if that helps main: ```c #include <stdio.h>...

[ ] meaning in code?

So it seems like this can be used to write down a pattern or something. Also how come is this made an unsigned long even though its not that big of a number? const unsigned long blinkPattern[ ] = {100, 500, 700, 2000};...
