Hi, My knowledge of electronics is pretty basic and hope someone can help.
I need to build a device that has 2 relays. Each time the device is powered up I need the alternate relay to be switched on.
ie
Power on - Relay 1 turns on
Power off
Power on - Relay 2 turns on
Power off
Power on - Relay 1 turns on
etc etc.
I can program microcontrollers and would normally just use one of them to do what I want, but it needs to remember the previous state and the only way I know to do that is write to eeprom. This is OK but the eeprom only has 100,000 read/write cycle and this thing will be switching a lot. Any suggestions or ideas how I can do this?
