Hi @jamessugrue — Welcome to the forum!
The basic idea looks good. It may be due to the way the alligator clips are connected. It’s easy for them to accidentally touch other connections and short circuit. I like to connect them as shown here: https://learn.adafruit.com/assets/49859 . MakeCode also has some documentation with suggestions to avoid shorts: https://makecode.microbit.org/device/crocodile-clips .
If that’s not the problem, you might also want to try another micro:bit. It’s possible that one of the I/O pins (P0) on the specific micro:bit is damaged.
