Hello,
I am working in a project where I need to illuminate 24 super LED and to adjust their intensity at 5 distinct levels.
The requirement for the project is like it should run in either 9V or 12V supply. The LEDs that we are planning to use is L1CU-BLU1000000000 (**broken link removed**)...
Hello,
I'm currently trying to build a range finder using NIR pulsed laser diode to achieve 100-150meters range. I'm planning to use four OSRAM's SPL PL90_3 Laser diodes ( https://www.mouser.com/ds/2/311/SPL%20PL90_3-461392.pdf ) to get ranges from different directions. I'm planning to use FPGA...
Thank you for reply,
kindly see my function implementation:
unsigned char getkey(void)
{
int i; char c;
PORTD=0X00;
for(i=16;i<130;i*=2) // for loop for row scanning
{
PORTD= i;
delay(3);
c=PORTC;
delay(3);
if(i==16){ // activating 1st row
switch(c){
case 0X10...
