Setelah menjalankan Asisten di perangkat, saatnya memperluas
dengan Tindakan Perangkat. Tindakan Perangkat memungkinkan Anda mengontrol perangkat melalui suara.
Untuk contoh ini, Anda akan menggunakan Tindakan Perangkat Bawaan
untuk menyalakan dan mematikan lampu.
Ikuti petunjuk berikut untuk memasang LED pada Raspberry Pi 3 Model B. Di
langkah selanjutnya, Anda akan mengubah kode contoh untuk menyalakan LED dengan perintah suara.
Persyaratan hardware
Sebelum memulai contoh ini, Anda memerlukan komponen berikut:
Breadboard
Sebuah LED
Resistor seri
Dua kabel jumper, dengan konektor laki-laki dan perempuan
Hambatan listrik resistor harus dikaitkan ke LED tertentu.
Untuk menemukan nilai yang benar, Anda dapat menggunakan kalkulator online (atau membeli kit).
Menghubungkan komponen
Hubungkan pin output GPIO BCM25
ke salah satu sisi resistor seri. Perhatikan bahwa ini adalah pin fisik 22
pada Raspberry Pi 3.
Hubungkan sisi lain resistor ke sisi anoda (sadapan lebih panjang)
LED.
Hubungkan sisi katode (katode kabel yang lebih pendek) ke LED.

Device Actions allow you to control your device via voice.\nFor this example, you will be using a [Built-in Device Action](/assistant/sdk/device-actions-overview#built-in)\nto turn a light on and off.\n\nFollow these instructions to install an LED on the Raspberry Pi 3 Model B. In a\nlater step, you will modify the sample code to light the LED by voice command.\n| **Note:** Don't worry if you don't have an LED at the moment.
