    Circuit Flip flop
AI Thread Summary
A D latch flip flop circuit can be used to control a relay for a light that toggles on and off with a momentary button. When the circuit is powered, the light turns on, and pressing the button alternates the light's state with a one-second delay. The relay operates by receiving a "1" signal from the flip flop to close the contactor, turning the light on, and a "0" signal to open the contactor, turning the light off. The discussion highlights a need for a ladder diagram to clarify the implementation of this logic with relays. Understanding the relationship between the D latch, flip flop, and relay operation is crucial for completing the circuit.

I need help! I'm really close to figuring out this Control Relay circuit but I'm running out of time.

Circuit Description: Plug in the circuit and the light turns on. Press the momentary button and the
light goes off. Press the momentary button again, and the light turns back on after one second.
Press the button again and the light goes back off. Repeat...

I've been reading on the D latch and Flip Flop logic a bunch, but I can't figure out how to apply it to
using relays! I know I'm missing something little can somebody help me PLEASE! If somebody could
draw a quick ladder diagram and upload a picture it would save lives. My co-workers and I are
stuck and out of time.

Doesn't a relay just fire a contactor? (takes a normally open switch and closes it). If the relay gets a signal of "1" from the flip flop, it shoud close the contactor and turn on light.

When relay gets a "0" from flip flop it should open contactor and turn light off.

As far as the "quick" ladder diagram...that's up to you!
