Description

GARAGE DOOR OPENER WITH TELEGRAM
-------------------------------------------------

A. Masalah

Setiap Project sudah pasti berawal dari sebuah masalah yang akan kami coba selesaikan. Masalah yang kami hadapi berawal dari:

• Masih harus turun dari mobil untuk membuka pintu garasi?
• Atau harus menelpon orang rumah untuk membuka pintu garasi?
   

B. Solusi

Solusi yang kami tawarkan yaitu Gerbang yang bisa di buka dengan aplikasi telegram. atau kamu sebut dengan “Garage Door Opener with Telegram”
 

C. Wiring Diagram

Pada project kami meggunakan beberapa Komponen atau Modul diantaranya:

1. NodeMCU ESP8266 Lolin
2. Baterai 9 Volt
3. Motor DC RS-545
4. Motor Driver L298N
5. Kabel Jumper

untuk lebih jelas pin nya kita jabarkan sebagai berikut:

• ENA >>> D7
• IN1 >>> D1
• IN2 >>> D2
• VCC sesuaikan
• Ground sesuaikan
