downtime - Rickey's World of Microcontrollers & Microprocessors

Dear members,
We are recovered from a huge server problem. I am really sorry to say but we have lost all the data including forum posts, chatbox posts, and registered users of past 7 days. I really apologize for this downtime. Our server admins are working to somehow get the data back.
Please bear with us.
Regards,
Ajay... Read Compelte post

Pins high is the normal state. You need a program to set them low
