#114811 - dont warry,, it is any one right .... Responding to: ???'s previous message |
it is any one right to use 555 instead of 8051 timer!!!
you arent allowed to force peaple to use internal timer!!! a good purpose of using 555 timer is release internal timer for other jobs... YOU CAN directly Connect pin 3 of 555 to microcontroler or use a capcitor for edge corrosing purpose if your 555 supply voltage is not same to microcontyroler voltage use of an optocoupler ================== I L O V E Y O U : 555 |
