Hi! I've built an SR latch with 2n3904 transistors (see attached schematics; VCC 5V) to control two dc motors through an L298 board. The motors go in one direction, and change direction when "opposite" momentary switch is closed (i e the vehicle hitting a wall...).
Now I want to introduce a small delay (appx 1 s?) before the L298 seeing a rising signal, but no delay on falling (eg: J1 is high, J2 low. Momentary switch hit, L298 should immediately "see" J1 going low, but there should be a short time period before the signal from J2 is seen as high).
I think I should be able to do this with capacitors and resistors on lines between L298 and J1/J2, but can't get it to work... I would really appreciate some help!
