Hi Andrew,
Thanks for the suggestion. I think its not working as I tried several things to increase the intensity. I also tried to add capacitor in parallel but instead of increasing intensity the LED was off. I am not getting to the final touch. What shd I do now?
thanks n Regards
Rishi
Thanks Andrew.
Yeah I can work on new design if it has good possibilities. Along with that I want to refine this design if possible. I will also try using higher brightness LEDs.
Tell me one thing will using the capacitors along with LEDs work.
I mean will it affect the ON-OFF time of LEDs...
Hey andrewr,
Thankx for your reply.
Actually we are using 2 DM134B as sink only. It is not being used for controlling the mosfet. The gate of Mosfet is connected to 220E pullup resistor with the 'st 74hc595' shift register being used as latch.
And I think yes u've understood the design...
Can anyone kindly help me in using the P channel mosfet as source for switching of LED display?
As I've connected it like 16 Mosfets with common source giving 5V from diode b/w power supply, drain is for the16 rows of 32 LEDs. Gate is connected to the shift register.
The problem is the...
