Inside the main loop function, we use the analog read function to read the voltage value from the pin A3 and A4. As we know the Arduino ADC output value from 0-1203 since it has a 10-bit ADC. This value has to be then converted to 0-5V which can be done by multiplying with (5...
You might be monitoring the output of a generator or solar array, you could be measuring the current consumption of your project or you might want to observe the charging and discharging of a battery. In this article, I will show you how to measure DC voltage and current using an Arduino...

If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH, 0V (ground) for LOW. 如果引脚被设置为INPUT,digitalWrite()会激活输入引脚的上拉电阻。
