I encountered a strange phenomenon this morning. The power supply is a three-phase four-wire system. The three-phase voltage is 380V balanced and the three-phase voltage to ground is 220V normal. The ...
The sensor outputs a weak DC signal (<1mV). Considering the influence of noise, it cannot be directly amplified, so I want to improve the signal-to-noise ratio. I found on the Internet that someone us...
I want to use a single-chip microcomputer 3.3v to control a transistor switch power supply circuit. The DC power supply is 9v and the current is 25ma. It is closed when the high level is high and disc...
Haha, let’s check for errors.The idea of this board:
1. Use 51 single chip microcomputer
2. Add a DS1302
3. A TFT LCD
4. 3 buttonsRealize LCD display: digital clock with temperature and humiditySchema...
