ArduinoDA elektron seyf yaratish

ISHNI BAJARISH UCHUN KERAKLI BO’LGAN QURILMALARNI TO’PLAB, TARTIBLAB OLAMIZ. BIZGA KERAKLI QURILMALAR:

• ARDUINO NO R3;
• 4x4 MATRITSALI KLAVIATURA;
• PEZO-ELEMENT (OVOZ CHIQARISH ELEMENTI);
• 2 TA RANGLI SVETADIOD;
• 220 Ω REZISTOR;
• MICRO SERVO QURILMASI;

Moslashuvchan matritsali klaviatura 4 dan 4 gacha. Arduino asosidagi loyihalarda axborot kiritish funksiyasini amalga oshirish uchun foydalaniladi.

QURILMALARNI QUYIDAGI TARTIBDA JOYLASHTIRIB OLAMIZ VA KABELLARNI ULAB CHIQAMIZ
