Hi,
I had solved my problem,i just changed ADC which was not working properly and displayed output on PC using serial communication,it's working properly now.
positive terminal of each LED is connected to port2 i.e P2^0 . . . . . . P2^7 and other end directly connected to ground.If i connect leds at ADC pins (D0-D7) output is upto some extent correct,for example if i have analogue input nearly zero,digital output is not zero,actually all leds should...
Hi,
I am using LDR,AT89S52,ADC0804 and the minimum analogue voltage at input of ADC0804 is not zero.If analouge input is in the range (1.8-4.8volt) then what will be the value of step size and Vref?LEDS connected to P2.
As i have to write a code such that
if input voltage is between (1.8-2.2)...

I want to use LDR,with the variation of light intensity it should give different voltages to Controller,The LEDS that are "ON" at a time should vary with respect to light intensity,let have five LEDS connected to controller.LDR will give only two voltage levels +5volt or 0volt but i want...
Hi all,
I want to use Light sensor,with variation of light intensity number of "on" LEDS should go on increasing,let have five LEDS.What should i use?LDR?
