hi guys I'm new to the circuit and I need your help..
ok here the sample question:
" as part of smart tunnel function monitoring system, a circuit is required to indicate the status of the tunnel valve. A green LED display turn on if all three valves are open. A red LED display turns on if any of the valves fail to open. When the tunnel valve isopen, its sensors produce a LOW voltage. When the tunnel valve is close, its sensor produces a HIGH voltage. Implement a logic gate circuit to meet this requirment."
*I've make the red led with nand gate, but my problem is LED should turn on if it HIGH right?
. the ques say "When the tunnel valve is open, its sensors produce a LOW voltage" that mean green led should turn on if all gate open then produce LOW, but how to make led turn on if it LOW... ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
