මේ ප්‍රොජෙක්ට් එක බොහොම සරලයි. අපි මේකෙදී කරන්න බලාපොරොත්තු වෙන්නේ Arduino Board එකේ Inbuilt තියෙන LED එක නිවි නිවී පත්තුවෙන්න සකස් කිරීමයි. මේ Inbuilt LED එක කිව්වේ L LED එක. ඔයගොල්ලො කලින් පෝස්ට් එක කියෙව්වනම් මේ L LED එක සවිවෙලා තියෙන්නේ Digital Pin 13 වලට කියලා මතක ඇති.. මේ Project එකේදී අපට වෙන කිසිම දෙයක් Arduino Board එකට එලියෙන් සවිකරන්න වුවමනා වෙන්නේ නෑ. Board එක තිබුනාම ඇති....

ඕනම Arduino programme එකක අනිවාර්‍රයෙන්ම තියෙන Structures දෙකක් තියෙනවා. ඒ තමයි "void setup ()" සහ "void loop ()" කියන Structures දෙක. අපි ලියන ප්‍රෝග්‍රෑම් එක දාන්න ඕන මේ "setup()" සහ "loop()" කියන කොටස් දෙක ඇතුලටයි. මේ දෙකෙන් "setup()" කියන එක අපි Programme එක ස්ටාර්ට් කරාම එක පාරක් වැඩකරලා ඊළඟට "loop()" කියන එකට යනවා. "loop" එක හැමදිස්සෙම ආපහු ආපහු වැඩ කරකර තමයි තියෙන්නේ. ඒ නිසා ඔයගොල්ලන්ට තේරෙනවා ඇති අපට ප්‍රෝග්‍රෑම් එකේ එකපාරක් විතරක් වෙන්න ඕන දෙවල් ටික "setup" එක ඇතුලට දාලා ඊළඟට repeat වෙන්න ඕන දෙවල් ටික "loop" එක ඇතුලට දාන්න ඕන බව..දැනට ඔය ටික ඇති....දැන් අපි වැඩේට බහිමු...


අපි දැන් අපේ ප්‍රෝග්‍රෑම් එකේ වෙන්න ඕන දෙවල්. ඒ කියන්නේ pseudo code එකක් වගේ එකක් ලියමු.( ඒ කියන්නේ අපේ ප්‍රෝග්‍රෑම් එක වැඩ කරන්න ඕනේ කොහොමද කියල... ) දැන් අපිට අපේ Pin 13 එකේ තියෙන LED එක Blink කරන්න නම් පහල තියෙන දේවල් කරන්න ඕන....

1) LED එක සවිකර ඇති Pin එක Pin 13 බව Arduino එකට පැවසීම.

2) එම Pin එක Output එකක් බවට පත් කිරීම.

3) LED එක දැල්වීම.

4) ටික වේලාවක් බලාසිටීම.

5) LED එක නීවීම.

6) ටික වේලාවක් බලාසිටීම.

7) නැවතත් අංක 3 වෙත යෑම.

ඔය පියවරවල් ටික බැලුවාම ඔයගොල්ලන්ට බොහොම පහසුවෙන් අවබෝධ කර ගන්න පුලුවන් දෙයක් තමයි ඔතන තියෙන පියවර 1 හා 2 එක පාරක් වැඩකරාම ඇති බව. නමුත් පියවරවල් 3 සිට 7 දක්වා නැවත නැවතත් Repeat වෙන්න ඕන. ඒ නිසා අපි ඔය පියවරවල් වලින් 1 සහ 2 දානවා එක "setup()" ඇතුලට. අනිත් ටික (3 සිට 7 දක්වා) දානවා "loop()" එක ඇතුලට.

එහෙනම් අපි දැන් ප්‍රෝග්‍රෑම් ලියන්න පටන් ගනිමු...එස්සේල්ලම අපි අපේ project එකට Arduino board එකෙන් ගන්න pin එක මොකක්ද කියල define(එකියන්නේ හඳුන්වන්න ඕනේ)කරන්න ඕනේ...මෙතැනදී අපි Use කරන්නේ 13 වෙනි පින් එක නිසා මම මෙහෙම එක define කරනවා..

int ledpin = 13;

මෙතැනදී අපි 13 වන pin එක ප්‍රෝග්‍රෑම්

එකට define කරනවා විතරක් නෙවෙයි.

මෙතැනදී අපි ledpin කියල වෙරියබල් එකක් හදනවා...

එකියන්නේ අපිට ප්‍රෝග්‍රෑම් එක ඇතුලෙදි(මෙතනින් පසුව)

13 වන pin එකට ledpin කියල කියන්න පුළුවන්... 

මේවගේ define කරන ඒවා අපි "setup" හා "loop" කියන දෙකම

කලින් කරන්න ඕන... 

දැන් ledpin එක output එකක් කරන එක අපි "setup" එක ඇතුලෙ කරන්න ඕන. ඒක මෙහෙම කරන්න පුලුවන්.

void setup() {                
  pinMode(ledpin, OUTPUT);

}

දැන් අපේ "loop" එක ආරම්භ කරන්න ඕන. ඒ සඳහා අවශ්‍ය සම්පූර්ණ කේත සටහනම මෙහෙමයි. 
void loop() {
  digitalWrite(ledpin, HIGH);
  delay(1000);
  digitalWrite(ledpin, LOW);
  delay(1000);
}
ඔතන තියෙන "digitalWrite" කියන function එකෙන් කෙරෙන්නේ අපේ outputs විදියට define කරලා තියෙන digital pins, on හරි off හරි කරන එකයි. ( HIGH කියන්නේ on කියන එකයි. LOW කියන්නේ off වලටයි )
ඒවගේම අපි "delay" කියන function එක භාවිතා කරන්නේ අපේ programme එක වැඩකිරීම යම්කිසි වේලාවකට නවත්වා තැබීමටයි. මෙතනදී නම් LED එක ඔන් කළාට පස්සේ ආපහු LED එක off වෙන්න කලින් තත්පරයක කාලයක් LED එක on තත්වයේම තබාගැනීම delay එක මඟින් මෙතනදී සිදුකරනවා. ( delay function එකෙදී අපි delay time එක ලබාදෙන්න ඕන මිලිතත්පර වලිනුයි.  එක තත්පරයකට මිලිතත්පර 1000ක් තියෙනවා. | | 1 second = 1000 milliseconds ) 

මෙතනදී වැදගත් දෙයක් කියන්න ඕනේ.

ඒ තමයි අපි දෙන හැම Code අවසානයේ ;

කියන සංකේතය දන්නා ඕනේ..

තවදෙයක් තම මතක් කරලම දාන හැම සඟල

වරහනක්ම වහන්නත් මතක තියාගන්න ඕනේ..

ඉතා වැදගත්! :- Arduino Language එක Case Sensitive. ඒ කියන්නේ කැපිටල් සහ සිම්පල් අකුරු හරි විදියට තියෙන්න ඕන. ඒ හින්දා මම මෙතනදී දෙන කෝඩ් එක ඒ තියෙන විදියටම ලියන්න. කැපිටල් සිම්පල් මාරු කරන්න එපා. 

උදා : - Digitalwrite() - මේක වැරදියි.

           DigitalWrite() - මේකත් වැරදියි. 

           digitalWrite()- මේ විදිය විතරයි හරි.

 
ඔන්න code සේරම ටික ලිව්වා...දැන් ඉතින් බෝඩ් එකට Power දීලා තියෙනකම් 13 වන pin එකට සෙට් වෙලා තියෙන LED එක blink වෙනචා..ඕනෙනම් අපිට 13 වන pin එකට LED එකක (-) අග්‍ර සවි කරලා අනිත් අග්‍රය(ඒ කියන්නේ (+)අග්‍රය) බෝඩ් එකේ තියෙන 3.3V  කියන තැනට 220onm විතර resistor එකක් එක්ක ඇල්ලුවොත් ඒ LED එකත් Blink වෙනවා...කරලා බලන්නකෝ...මෙකට Project Board එකක් ගත්තොත් ලේසි...පාඩුවක් වෙන්නේ එකක් ගත්ත කියල මොකද අපි ඉස්සරහට කරන Project බොහොමයකටම අපිට Project Board එකක් ඕනේ වෙන්නේ නෑ....මේකක් සාමාන්‍යයෙන් RS.250-300ක් විතර වෙන්නේ....තව අපි ඉස්සරහට කරන Project වලට jumper cabels එහෙමත් ඕනේ වෙනවා...ඒවත් RS.200ක් විතර වෙනවා...මේ ඔක්කොම බඩු ටික ඔයාලට ලේසියෙන්ම ගන්න පුළුවන් කොටුවේ පලවෙනි හරස් වීදියේ යුනිටෙක් කියන කඩෙන්...
ඔන්න එහෙනම් පහලින් බලා ගන්නකො..අද අපි ලියපු සම්පුර්ණ ප්‍රෝග්‍රෑම් එක...

int ledpin = 13;

void setup() {                
  pinMode(ledpin, OUTPUT);     
}

void loop() {
  digitalWrite(ledpin, HIGH);
  delay(1000);
  digitalWrite(ledpin, LOW);
  delay(1000);
}

දැන් අපේ ප්‍රෝග්‍රෑම් එක සම්පූර්ණයි! දැන් ඉතින් Arduino IDE එකේ තියෙන Upload Button එක ඔබලා ප්‍රෝග්‍රෑම් එක බෝඩ් එකට upload කරන්න. 

                                               

වැඩේ හරියට කළානම් LED එක නිවී නිවී පත්තු වෙන්න ඕන. මේ වීඩියෝ එක බලන්න....

Arduino programming(හැඳින්වීම)

සුභ දවසක් යාලුවනේ.......
ඔන්න මම අද ඉඳන් අලුත් ලිපි පෙළක් ලියන්න යනවා...
ඒ තමයි Arduino programming ගැන...
සමහර අය මේ ගැන දන්නවත් ඇති දැනටම....ඒ වුනාට කමක් නැ...
මම හැමදේම මුල ඉඳන් කියලා දෙන්නම්......

ඔන්න එහෙනම් අපි මුලින්ම බලමු.....මේ Arduino කියන්නේ මොකක්ද? කියලා...
මේක හදපු Arduino.cc එකේ අය Arduino ගැන මෙහෙම කියනවා....

"Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments."

From Arduino.cc

ඕකේ තියෙන වැඩක් ඇති දේවල් ටික නම්,

1) Arduino කියන්නේ සම්පූර්නයෙන්ම නිදහස් දෘඩාංග සහ මෘදුකාංග වලින් සැදුම්ලත් එකක්. Arduino වලට අදාල ඕනම ක්‍රමානුරූප (Schematics) ඕන දෙයක් ඒගොල්ලන්ගෙම වෙබ්සයිට් එකක් ඩවුන් කරගන්න පුලුවන්.

2) Easy-to-use - ඇත්තටම Arduino වලින් ප්‍රෝග්‍රෑම් කරන එක සහ Arduino සම්බන්ධ පරිපථ නිර්මාණය හරිම සිම්පල් වැඩක්. ඒවා අපි ඊළඟට බලමුකෝ..

‍
සරලවම කිව්වොත් Arduino කියන්නේ අපි විසින් එයට දෙන උපදෙස් වලට අනුව එය වැඩ කරනවා....එම නිසා අපිට Arduino මගින් LED පරිපථ වැනි සරල දේවල් වල සිට රොබෝවරු නිර්මාණය වැනි සංකීර්ණ වැඩ කිරීමට‍ද හැක...


දැන් සමහර අයට ගැටළුවක් එනවා ඇති PIC සහ Arduino අතර තියෙන වෙනස්කම් මොනවද කියලා.

• PIC සහ Arduino අතර තියෙන ප්‍රධානම වෙනස්කම තමයි PIC කියන්නේ නිකම්ම Microprocessor එකක් විතරයි.

• ඒවුනාට Arduino කියන්නේ සම්පූර්ණ prototyping platform එකක්. platform එකක microprocessor එකට අමතරව ප්‍රොග්‍රැමර් එකක් සහ power supply එකක් සහ පරිගණකය හා සම්බන්ධ කරන ක්‍රමයක් (USB or Serial) යන සියල්ලම අන්තර්ගත වෙනවා. 

• ඒ කියන්නේ අපි Arduino බෝඩ් එකක් මිලදී ගත්තාම ඒක කෙලින්ම පරිගණකයට සම්බන්ධ කරල වැඩ පටන්ගන්න පුලුවන්.  

 දැන් ඉතින් විස්තර ගොඩක් මම කිව්වා....
අපිට  Arduino programming වලට ගන්න පුළුවන් Board විශාල ප්‍රමාණයක් තියෙනවා...
ඒ අතරින් අඩු මුදලකට ගන්න පුළුවන් බෝඩ් එක තමයි Arduino UNO  බෝඩ් එක.
