3 and 1/2 LCD (liquid crystal) digital display (DMS-20LCD)
Source: InternetPublisher:萌面大虾 Keywords: LCD liquid crystal digital display Updated: 2021/03/17
LCD (liquid crystal) digital display ( DM S-20 LCD ). In this circuit, the analog signal is added
between OI and @ pins, and the battery power supply terminal is ① and @ pins. After the analog signal is operationally amplified, the A/D converter measures the signal and changes it into a digital signal, which then
drives the LCD digital display to display the level value of the analog signal in digital form.
