I am new to this and need some help. I have developed ,loaded and executed a program. The problem is when I power down,wait for awhile then power back up the Program is gone. I thought the Flash was permanent until reloaded. Am I doing something wrong?
It is permanent - something is going wrong. You aren't activating the erase button?
You are using standard Arduino 1.5.7 environment? Programming port?
I figured it out . I was stupid. the program was still there but since it sent data over the USB the send buffer went full between disconnecting the USB and Power all i had to do was reestablish communications and the program started sending data.
