Hi Ca this be used with 6 volt to drive a 6 volt motor

Asked by: JohnA
The 555 timer circuit requires a 12v supply to operate, however the relay attached will switch anything below its maximum of 24V 10A so should be fine for a 6V supply to a motor. A full circuit diagram can be found at the link below, if it will help;
