THE STRANGE CLOCK IN NTP

Dear ElectroFriends, I haven't seen new publications for some time .... I hope it's not the fault of some virus and I hope you are all in good health. I personally don't have (Luckily) problems, but from a social point of view it ...

Nyquist-Shannon theorem

. Comprensione dei sistemi campionati Il teorema di campionamento di Nyquist, or more precisely the Nyquist-Shannon theorem, it is a fundamental theoretical principle that governs the design of mixed signal electronic systems. Technology…

Low resistance meter

  Create a circuit for the precise measurement of low resistances. You already have a DMM to measure resistance, but it can be used with resistances lower than 1Ω? And if so, these low resistive readings are reliable? This…

The IGBT Protection

. Principio di funzionamento I primi IGBT erano tiristori modificati per potersi accendere con un comando in tensione. Consider the BJT equivalent circuit of a thyristor and a MOSFET transistor is added between the collector and emitter ...

Controlling Water Filter

Acqua filtrata con Arduino Descrizione In casa si usa bere acqua filtrata. In fact it is found that sometimes cleaning the filter cartridge demonstrates a muddy patina and for this reason there is the preference to filter drinking water. The year…

Albert Einstein and the GPS

. I'm a big fan of Albert Einstein. Many physicists would agree that his theories are the purest expression of genius in the history of humanity with all the ensuing applications. In this case, we talk about the Global ...

Control with Bluetooth Nano

With a bit 'of time available I thought of putting on a via bluetooth control. The thing is quite simple using those modules available on the market. I took a HC-06, It allows simple data communications ...

Bluetooth control with 12F675

  This is a simple control via Bluetooth. The thing is quick to implement using those modules available on the market. With a HC-06 and a few components you create an easy control with the data communication via serial. The…

Movement controlled encoder

Descrizione Semplice controllo di rotazione con motoriduttore che ha un encoder a due fasi montato sull’albero del motorino elettrico. During the tests I burned the 16F84A I had and for this I used a 16F628A. The program…

lights Game with Arduino

Inspired by a friend of mine, I have developed a circuit to light a matrix of LEDs. Is it possible that the pastor has requested to repair a votive candle, already provided with the incandescent lights. We made ...
