Dear Friends,
Attached the schematic, I have designed Atmega329P as standalone system. The Atmega328 programming / debugging is configured using Arduino Uno using Tx, Rx, Reset and Gnd. This is working perfectly right.
Whenever I disconnect Arduino Uno, Ralay failed to start. Kindly guide how to proceed further.
