Lets build LED flaser, only three LEDs. If put red yellow green.. it's become trafic light ?? huh . add more transistor with many LEDs.. perhaps can maka marching ants LED as Border Movingsign .. :D here my skecth scheme oopps is that scheme? looks like layout board huh?.. here there is source code, use avrstudio4 to build and compile: #define F_CPU 1000000UL #include #include #include #include #include uint8_t a,b; //===================================== int main(void) { DDRB = 0b11111; // set output semua PORTB =0b11111; //nilai awal a=0b11111; while(1) { if (a==0) a=0b11111; a=a / 2; PORTB=a; _delay_ms(100); } } i ask someone to create PCB.. i hate when i must use chemical for eth that PCB. and drill makes many holes? booring..!!! here the PCB ready to put together with spareparts what next ? sorry to be contiuned.. still have busy hour work at office.. see you soon. i also posted in http://www.pcbway.com/project/shar...

hello there.. now a write about my first experience use Universal PCB from PCBway. Ususaly I called it PCB Hole Donut. because.. the shape every hole surrounded by copper looks like hundred pieces of donut. here the pic : log : --------- 6/20/2016 i will write post when thats PCB arrived 7/7/2016 my order has arrived... capture quote from PCB way project page. " The PCBWay-Yards that recognize the talent and effort of the best electronic designers in the World".

masih banyak yang cari versi 4 karena lebih ringan dan tidak makan tempat. tidak perlu net framework dan kebutuhannya cuman untuk memrogrm IC atmega standar ngga aneh aneh. Dibawah ini variannya banyak.. aku pake yg atmel studio 4.14 klo yg lebih tinggi sepertinya makan banyak tempat.

wah ada yang suka gratisan, ini temen grup elektornika mau bagi bagi pcb atmega8. ditunggu..

PCB from Alex (my friend at Bandung)

lets make modul display board use IC digital 4026. first i type pcb 4026 . i found this layout pcb from www.eleccircuit.com. then i create from this. but it's still have poor quality images...

do you have mini systemboard atmega16 ? ye i have one. but until this march. i dont know how program it. otherwise perhaps you have simple program? such as how to driving seven segmen? I try to design with 2x10 data connector header male - female. so its look likes shield on arduino uno. acording to board size 5x7cm not far from that size. start using Universal PCB from PCBway. i found that 3x7cm board meet my requirment.
