Introduction: Seconds Counter for Binary Clock
; the idea ;
32+16+8+4 = 60 sec
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: At Beginning :
first of All sorry for my poor English :|
in this instructable I'll show you How to make "binary clock" beginning from seconds counter to minute and Hour in final
Step 2: Why Bascom Avr ?
I used bascom language to programming -ATMIGA8L-
,it was a High level language
and has about 130 instruction
with a clearly and easy directives
so , the " bascomian programers"
:-D would know this /5/ standard principles in programing :
1- Directives (the mcu, crystal..
2- configuration (pin,port,ADC..
3- variables (x,y...
4- main program
and you there should follow this sentences at any program
you write it
Step 3: Schematic :
'6 leds (3mm)
'6 resistors ( 200 ohm ...)
'1 microcontroller (in my case atmega8l)
connect each components like the picture
Step 4: On Test Board :
after we connected the components
it's well be like the first picture
we connect the leds directly to controller because they deserve just 10 mA from 1 pin
and from all pins 60 mA
and my controller can resist this value (it can resist up to 300 mA)
optionally component ;
- I added sponge cap from (old watch box) I have cut it from centre to fitting the leds ( it's black to absorb the light and to see the clock clearly )
Step 5: The Program :
$crystal = 1000000
config portc =&B00111111
*maim program :
Step 6: The End
in the result we had got
picture 1 : 0
and after one second
picture 2 : 1
..picture 3 : 2
picture 4 : 3
5. : 4
