    TinkerCAD 7-Segment Display Not Showing on Simulation

    Hi, I am only on my 5th week trying out TinkerCAD for our Logic Circuits course. We are tasked to create a 7-Segment Display Using Logic Gates only. I did all the boolean expressions needed for each segment using K-MAP, and identified the boolean expression needed to create my circuit. I am...

    Touchless Toggle Switch Help

    Need help simplifying this project as arduino is abit overkill for this application. I am abit noob at electronics and wondering if there are any IC's or modules that will simplify or make this project more efficient. Thanks. Description IR-1 and IR-2 are IR obstacle avoidance sensor modules...

    How to draw this logic circuit?

    Hello. This is JK flip-flop. I have to convert it into D flip-flop, that it does the same what JK does. Then I have to draw a logic circuit of D flip-flop. I don't know what to do, can you help me?

    Arithmetic - Absolut Value

    I want to construct a circuit that calculates the absolute value of a signed 4-bit number in two's complement! So the logic here : assuming we have B = b3 b2 b1 b0 . If b3 is '1' then then b is already in 2s complemnt and should be assigned directly to the output else if b3 is equal to '0' then...

    Keep MOSFET "ON" for a certain time

    Hello everyone! I'm currently designing a simple circuit which is working as I want but I'd like to make sure that I haven't done any dumb mistake. That's why I'm asking here. I'd like a signal to switch ON a MOSFET in order to activate a relay. This signal is usually low (0 VDC) but sometimes...
