DC Motor Speed Control

Berikut tahap-tahap dalam membuat DC Motor Speed Control dengan AVR
Alat-alat yang dibutuhkan adalah sebagai berikut:

1. ATMEGA-16
2. 1N4148 —> Driver Motor
3. Led-Bargraph-Green —> Indikator Speed
4. Motor-DC

Langkah selanjutnya adalah melakukan simulasi dengan menggunakan beberapa software pendukung, software yang dibutuhkan adalah:

1. Proteus(ISIS 7 Professional)
2. Bascom-AVR

Mari kita mulai untuk melakukan simulasi terlebih dahulu:

1. Buatlah rangkaian sesuai dengan gambar di bawah ini dengan menggunakan Software Proteus(ISIS 7 Profesional):
2. setelah selesai merangkai gunakan software Bascom-AVR dengan mengetikkan kode sebagai berikut:

$regfile = “m16def.dat”
$crystal = 1000000
