the current rushed into the Gate of the MOSFET when output pin state is HIGH would be very large and would thus turn the MOSFET instantaneously on. This would create a very large inrush current due to the nature of the motors inductor, which would drop the battery voltage significantly enoug...
we might want to check the battery voltage if it needs to be charged or replaced. It happens to me with myRC Panzer. Sometimes when my kids are about to run it, it moves very slow, low battery. Then they are disappointed and need to wait for charging time. I would rather had notice...

此外,我还可以自己绘制符号作为位图字体。 这些符号包括 Battery low(电量低)、Battery empty(电量耗尽),以及显示气压升降的四个象形图。 我的绘画能力远远低于我的编码能力,请见谅。 我将 3.3V 导线上的 Battery low(电量低)和 Battery empty(电量耗尽)分别定义为 3.0 V 和 2.9 V。
Hello, I am currently programing an ESP32 C3 devboard which has multiple ADC channels and i would like to read data from 3 different sensors. The problem is that whenever i use analogRead() with any port it always only shows the measurme...
