Good day to all,
I am working on a personal project to control high power led in my garden, which require 200 high power led. I working in phase manner. I successes in controlling the 8 LEDs using sn74hc595 and uln2803alg ic and later I wired 5 sn74hc595 and uln2803alg that too I succeed,
now I want to add 25 sn74hc595 on one circuit board and 25 uln2803alg one on other and connect using individual connectors. (This to reduce distance between shift register to minimise noise add on)
So as mentioned above I want some guidance regarding powering 25 shift register voltage and current. I have decoupling 0.1 uf for each shift register.
Can I drive all shift register using 5v 800mA dc power. This only to power shift register 25 unit board only. Please help
