some time ago, I posted a circuit that was incomplete. RadioRon helped me out some by giving a logic diagram of the chips I need to make my circuit work. I was asking for the pinout diagram which shows the arrangement of the pins on the IC chip, when ppl griped about me wanting them to do the circuit. I just was interested in the IC pinout instead of the circuit diagram. Looking back at that circuit after time has passed and I temporarily lost interest in the circuit, I have come back to it and want to finish it. In the circuit, when the water level gets below the Upper Water Level Sensor, I want it to turn on a LED, which warns of the low water level in the cell. I changed my mind in the method of turning the LEDs in my circuit, i thought about possibly using a MOSFET or similar chip to control the LEDs. What MOSFETs or similar ICs can I use for that simple switching?
