Last week I explained how to use a motion sensor to trigger an event with an Arduino. The event we triggered was a simple blinking of an LED. You can do a lot with a bunch of LEDs if you use your ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

The output voltage of a voltage reference device can be adjusted using a digitally controlled potentiometer (DCP) without significantly changing the device’s temperature coefficient (TC), which ...
