Adding intro levels today!

I solved it but I had to use 'two' NMOS transistors unlike the direction.

Wire an NMOS transistor so that when In is 1, the output is pulled to ground (0). When In is 0, the output should be unconnected (Z).

The way it's worded it sounds like you need 'an NMOS' ie a single one? So I messed around but then I remembered seeing gates made from two transistors in my dusty memory.

(edit) I see there _is_ a one transistor solution... I'm pretty sure I tried that though. :/

lol, mb. As in understand it, its that the colors of the bg make it seem like its wires when its not, I'll change the color theme a bit to fix (plz correct me if my understanding is wrong)

Yes, that's the issue: the (thick) solid grey "major axis" lines on the background seemed to be a wire.

If I could make a recommendation, get rid of the grid lines entirely and only have 'dots' at regular spacing. Here's what Cadence Virtuoso looks like (the most popular circuit schematic tool for integrated circuit design):

Will do, thx! Coming in the next push

consider a colorblind mode that uses patterns instead of colors for those of us that are color-challenged

the part that tripped me up is 0 showing in deep RED and I thought that meant I was doing something wrong. I came here, read this and realized I was actually right and then pressed the Run tests button and passed. This is a UX thing you'd want to address

makes sense, ill change the color a bit in the next update

Did you switch to software?
reply
Yes. But, looking at BRCM/AVGO's stock chart, I may have made a mistake.
