Now you can build your very own flux capacitor ... along with LED lights and a pre-assembled, flexible circuit board. The battery pack comes with an on and off switch, which makes it easier ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

Adding to the ever growing list of Ardunio watches being created a new LED Arduino watch has been created ... video demonstration embed below. Super capacitors are new power source, compared ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno ...

I can tell when it's almost fully charged by looking at the value of the voltage across the capacitor. Next, disconnect the batteries and then close the switch so that the capacitor discharges ...
