In order to use the Arduino analog inputs to read voltages above 5 volt (actually above V REF, see here for more details), we need to design a voltage divider to divide the large voltage into a ...

Voltage Divider Monitor Most mobile robots have batteries to drive them, even the noisy ones powered by an engine. You have to make sure not to discharge you battery below a certain voltage to protect ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal ...

Fortunately, Arduino boards have a 3.3V regulated output that can be used to power the 23K256 chip. It is also quite easy to adapt the SS, SCLK and MOSI signals with simple 2-resistor voltage dividers ...

When we do textbook analysis, we tend to ignore the real-world concerns for the sake of learning. So, a typical theoretical voltage divider is simply two resistors. But if you examine a low-pass ...
