Recall that digitalWrite() is the command linked with digital output. Now let's introduce the corresponding command for digital input : digitalRead(). digitalRead() works similarly to its ...

With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16x2 LCD display.. Arduino has ...

In the second circuit, as the range is to be increased from 5V to 50V, a voltage divider configuration must be made. The voltage divider circuit is made by using a 10k-ohm and a 100k-ohm resistor.

The Power Supply schematic includes a 5vdc Sensor regulator. This reduces the load (and heat generated) on the Arduino on-board linear regulator, and also allows more effective input protection by ...

The simple code generates digital tones with the Arduino and broadcasts on Left channel (L) to prove connectivity and transmission frequency. The hardware shown below is able to take in stereo audio ...

A multimeter is a must-have tool in your arsenal when it comes to creating or developing electrical circuits.Without it, executing a job will be extremely tough. So, in this post, we chose to create a ...

Figure 1b shows how to connect a low-side digital input (S2) to an output pin of the L9822. Again, the output pin is maintained off. If S2 is off, the diagnostic status will not indicate any fault.
