Running LED Kit

Description

Kit running LED ini dapat digunakan sebagai kit belajar dan hobby elektronika, lampu LED akan berputar rotasi dengan kecepatan bisa diatur.

Arah rotasi hanya 1 arah yaitu searah jarum jam Clockwise (CW)

Kit ini belum disolder jadi diperlukan waktu dan alat menyolder sebelum dapat menggunakannya.

Isi kit
1 x PCB
20 x lampu LED merah 5mm
1 x elko 47uF
1 x elko 22uF
1 x R. 180 ohm
1 x dioda
1 x potensiometer 20K ohm
1 x IC 555
1 x IC 4017

Belum termasuk batere dan catu daya, menggunakan tegangan 6Volt DC – 12 Volt DC (maksimal)

Contoh hasil yang didapat setelah disolder :

Aplikasi lanjutan : Penggunaan running led bersama dengan Arduino UNO R3 :

Untuk menggunakan Arduino sebagai ganti dari IC Logic 4017 dan IC 555, kita hubungkan dari soket IC yang terdapat pada PCB, menggunakan kabel jumper male to male ke Arduino UNO.
