I want to use transistors in my control circuit, but am at a loss as what connects where. I need in my circuit diagram transistors to act as switches. How would I connect them if I wanted them to switch when one section of my main circuit loses power, turning on or Off LEDs. The way I want it, the transistors will switch when there is a loss of current going between the two posts of the upper or lower water level sensors, thus activating each individual LED or series of LEDSThis is kind of an offshoot of the thread Control Circuit help. I have established the main portion of the circuit and now I want to be able to control the indicator circuit that I have also designed, with the aid of my fellow members here on this forum. . I've been redesigning the circuits using PCB Artist and have compacted the circuits to a much smaller area. I just can't figure out how to output them in an image format that can be posted here.
