Proyek ini merupakan sistem kontrol LED nirkabel menggunakan ESP32 dan Bluetooth. Pengguna dapat menyalakan atau mematikan LED hanya dengan mengirimkan perintah dari aplikasi Bluetooth pada smartphone atau komputer. Proyek ini sangat cocok untuk pemula yang ingin memahami dasar komunikasi Bluetooth serial dan kontrol output digital menggunakan ESP32.<\/p>\n\n\n\n

Cara Kerja:<\/strong><\/p>\n\n\n\n

    \n
  1. ESP32 menginisialisasi koneksi Bluetooth dengan nama “NAMA_BLUETOOTH”.<\/li>\n\n\n\n
  2. Pengguna menghubungkan perangkat (smartphone\/PC) ke ESP32 melalui Bluetooth.<\/li>\n\n\n\n
  3. Ketika pengguna mengirim:\n
      \n
    • Karakter ‘1’ \u2192 LED menyala.<\/li>\n\n\n\n
    • Karakter ‘0’ \u2192 LED mati.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Data yang diterima juga ditampilkan di Serial Monitor untuk keperluan debugging atau observasi.<\/li>\n<\/ol>\n\n\n\n

      Komponen yang Digunakan:<\/strong><\/p>\n\n\n\n

        \n
      • 1 \u00d7 ESP32<\/li>\n\n\n\n
      • 1 x LED<\/li>\n\n\n\n
      • 1 x Resistor 220\u03a9 (untuk membatasi arus LED)<\/li>\n\n\n\n
      • Kabel jumper<\/li>\n\n\n\n
      • 1 x Breadboard<\/li>\n\n\n\n
      • 1 x Kabel USB (untuk upload dan power)<\/li>\n<\/ul>\n\n\n\n
