The difficulty of deploying the ESP32 series development environment has always been criticized. The first thing to be criticized is the various deceptive tutorials on the
In the last issue, we tested the DHT11 temperature and humidity sensor on the expansion board. This time, we are using the P98132 chip above to drive the RGB light.Let's take a look at the schematic d
Working frequency: the resonant frequency of the piezoelectric chip. The longer the wavelength, the smaller the frequency, the greater the detection distance, but the accuracy will be reduced. Sensit
