7-Segment dice

is it cytron have a class for study programming?

We do have workshop for PIC microcontroller, yet it is based on C programming, and it is very packed for a beginner

It is good to see you are taking initiative to learn, keep it going and we really hope to see more project and more members helping up. Do help up the others as others helped you.

BTW, I have send your video link to our facebook admin, they have posted at Cytron facebook wall. Hope your video can motivate and encourage more to start.

Get free coding here, but you need to have intention to study on your own.

nice website....
i will bookmark it..

Just my sudden thought, kind of agree with generating the number from key press.

Though is not really random, but if the microcontroller is running at 20MHz, and each instruction is executed at 200ns. If changing the number at 7-segment take a few instructions, it will take around 1us to 2us. Basically no one cannot see and also predict the number that will appear on 7seg when it release the keypress.

Therefore it become random

Myke Predko has a smarter way to generate random number. Page 128 of my "Evil Genius" book has an example on how to generate random number using TMR0. The result is an integer between 0 and 255:

OPTION = 0b01001111; // Run TMR0 From PIC MCU Clock
;
;
; when random number is needed:
;
i = TMR0; // Save TMR0 Value
if (i > 100) // Convert TMR0 Value to Decimal
LCDWrite((i / 100) + '0', 1);
else // No Hundreds to Display
LCDWrite(' ', 1);
if (i > 10)
{
i = i % 100; // Not Greater than 10
LCDWrite((i / 10) + '0', 1);
}
else
LCDWrite(' ', 1);
LCDWrite((i % 10) + '0', 1);

As the program is copyrighted. I can only extract a portion out of the whole program.

The random number part from the "Flickering Candle" experiment in his book is also very useful. He is using the Linear Shift Feedback Register (LFSR). The idea isn't all that new, but it's a pretty neat trick.

All of us here understand exactly how you feel, cause once upon a time, we never know how to write a code either!
We grew from books, internet, reading, and basically experiment (and that was the toughest parts!). Personally, I learn from one book I get from the library. My first program is just a simple 4-5 lines of code blinking 1 LED, copy paste from the book. As I grow and write better program, I gave up few times, take a break for few weeks/months, and then start picking up from where I left. And I am still working on the same project since..

Starting is most difficult, but once you have the first success, it become easier. But still, it is easiest to say I don't know please help.

i am kicking off my programming life the same way too....*passion of the codes*. with you guys i know i am going to get far.
