4 and 1/2 LED digital display (DMS-40PC series)
Source: InternetPublisher:蓝猫淘气 Keywords: LED digital display PC Updated: 2020/09/09
Shown is an LED digital display ( DM S-40 PC Series). As can be seen from the figure, the measured analog signal is added to the @ and
@ pins, is amplified in the module, and then sent to the A/D converter to convert the analog input signal into a digital signal, and finally drives the light-emitting diode
( LED ). Digital display shows the voltage value.
