Salam jumpa..,
Ok tmen2 kali ni ane mo share sama kalian tentang job yg
pernah ane dapet suruh buat tulisan pake led tapi dengan biaya murah..,(lain waktu
akan ane share cara buat running text).
Yang ini trbilang ckup mudah meskipun sudah berbasis
microcontroller.,tpi hnya sebagai switching, so cek aja langsung di sini…,
Pertama mesti siapin komponennya :
- Led (terserah warna apa sesuai selera, disini ane pake merah)
- Papan PCB matrik alias Pcb lobang
- Transistor NPN 2N222
- Microcontroller (ane pake ATtiny26)kbetulan sisa proyek.,pikir2 hemat ongkos hehe
- Kabel secukupnya (bisa pake kabel pelangi)
- tentunya solder & timah
Dan untuk power supply 5V bisa dlihat di artikel ni http://qabulbee.blogspot.com/2012/02/power-suppy-5v-9v-dan-12v.html
buat ja supply yg 5 volt.,tentunya untuk rangkaian TEXT LED diatas.
dan untuk contoh skema rangkaian sebagai berikut :
diatas adalah sampel untuk huruf I sedangkan huruf laen kreasi sendiri sesuaikan dengan tulisan yg mau dibuat..,
dan untuk program ane buat pake BASCOM, ni sampelnya :
