Physical display descriptionThere
are two potentiometers under the OLED (one potentiometer was burned, and the new potentiometer has not arrived yet). The voltage can be adjusted through the potentiometer and displayed on the OLED.
NotesThe
maximum voltage of the OUT2 part is 12V. OUT1 is infinitely refreshed, and the maximum can be the battery voltage.
Demo video
tips: You can upload attachments for the demonstration video. The maximum attachment can only be a 50M file. Files larger than 50M can be placed on other network disks or video websites. Just put the address link here.
Other attachment upload
tips: Participating works must upload project-related program attachments to the open source platform or personal code storage cloud. The maximum attachment supports 50M upload (please do not upload in the LiChuang workspace, there are restrictions)
