I need a circuit designed AS SIMPLE AS POSSIBLE to do the following:
When a switch ("main switch") is closed the circuit turns on for 30 seconds.
The circuit includes the following:
- One LED
- Two rapidly flashing LEDs
This circuit is to "time out" even if the main switch is closed.
Else, the lights are to turn off if the main switch is open.
This circuit can use either a 555 timer, or individual components.
MUST be VERY small for final assembly.
This is to operate from two CR2032 (3V) batteries or three LR44 (1.5V) batteries.
I require ONLY the designed circuit schematic.
Circuit will have to be proven before payment.
Please email for any further question.
