HELLO,
HELLO I NEED A CIRCUIT THAT WILL RAMP FROM 0 TO 12vdc IN 1/2 SECOND THEN RAMP DOWN FROM 12VDC TO 0 IN 1/2 SECOND the load is .5 amp, (Voltage Wabbler) This circuit does not need to be precise, some adjustment for the time using a trimmer pot would be nice. Basically it would be like turning a potentiometer up and down over a 1 second period, This circuit would be turned on by a 555 timer and would free run as long as the timer signal output is on.
Any help is appreciated
