Digital Clock Arduino LCD 16x2 + DHT11 (Pemantau Suhu + Jam)

Ide dari pembuatan Project ini adalah dari masalah yang timbul yaitu kurangnya alat pemantauan suhu ruangan. maka dalam project kali ini saya membuat project pendeteksi Suhu dan Kelembapan yang menggunakan Sensor DHT11. Alat ini saya lengkapi dengan penampil Jam Digital yang dapat bermanfaat juga selain hanya menampilkan Suhu Dan Kelembapan.
