Level Shifting

A project log for Internet Controlled VCR

I'm giving some VCRs internet controlled. Maybe Twitch.

I level shifted the 5v VFD display lines using voltage dividers. I used this method as it was the easiest to implement in the current circuit. On the Oscilloscope the line I tapped is reading 3.6v. A little too close to voltage logic high of the ESP32, but I'm not changing it now. I used 1K resistors inline, with 2k pulldowns.
