Waa maxay Microcontroller?
Microcontroller waa kombiyuutar yar oo ku jira hal wareeg oo isku dhafan (IC) oo loogu talagalay in lagu xakameeyo aaladaha elektarooniga ah. Microcontroller-ku wuxuu caadi ahaan ka kooban yahay:
– Cutubka Habaynta Dhexe (CPU)

Barnaamijka Koowaad - "Hello World" oo leh LED
Mid ka mid ah mashaariicda ugu horreeya ee ay dadka bilowga ah badanaa sameeyaan waa inay iftiimiyaan LED-ka, oo sidoo kale loo yaqaan barnaamijka "Hello World" ee barnaamijyada microcontroller.

2. Qor Koodhka Barnaamijka: Geli koodhka soo socda si aad u iftiimiso LED-ka ku dhex jira ee ku yaal pin 13.
“`c
Mudnaan madhan () {
// Deji biinka 13 sida OUTPUT
pinMode (13, OUTPUT);
}
loox madhan () {
Qor dijitaal ah(13, SARE); // Daar LED-ka shid
dib u dhac (1000); // Sug 1 ilbiriqsi
Qor dijitaal ah(13, HOOSE); // Dami LED-ka
dib u dhac (1000); // Sug 1 ilbiriqsi
}
““
3. Soo rar Barnaamijka: Guji badhanka 'Upload' ee ku jira Arduino IDE si aad koodka ugu rarto guddiga Arduino. LED-ka ku yaal biinka 13 wuxuu bilaabi doonaa inuu libiqsado 1 ilbiriqsi gudahood.

Biinanka I/O waa is-dhexgalka koowaad ee uu microcontroller-ku u isticmaalo inuu kula xiriiro adduunka dibadda. Biinankaan waxaa loo habeyn karaa sidii wax soo gelin ama wax soo saar. `pinMode()` waxaa loo isticmaalaa in lagu dejiyo qaabka biinka, `digitalWrite()` waxaa loo isticmaalaa in lagu qoro qiimaha macquulka biinka, iyo `digitalRead()` waxaa loo isticmaalaa in lagu akhriyo qiimaha macquulka biinka.

Barnaamijinta Microcontroller waa xirfad aad u faa'iido badan oo xiiso leh. In kasta oo ay u ekaan karto mid adag marka hore, dulqaad yar iyo ku celcelin, haddana dhawaan waxaad abuuri doontaa mashaariicdaada.
