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".
