“Part Fill” Valve? Yes, Part Fill valves are widely used in Rainwater tanks. The valve will open once the water level in the tank has fallen to a low position, this allows the town mains water to enter the tank and, when the water level reaches the minimum level, the valve closes. This arrangement is […]

Anche quest’anno Arduino partecipa a Robotica – mentre non partecipa Makersitaly! – e ha scelto il mezzo della stampante termica in controtendenza con i mille volantini, flyer, cataloghi, allegati, biglietti da visita e tutta la montagna di carta che avrete nelle tasche alla fine dei tre giorni – giovedì venerdì e sabato – della manifestazione.

Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD. The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V. Voltages are displayed with

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential applications for the chip, called LTC6268, include interfacing ADCs to reverse leakage (linear) mode photodiodes. 20kΩ transimpedance gain is available at 65MHz, and 499kΩ with 11MHz
Sub-picoamp input op-amp offers high gain bandwidth Continue Reading
The games market may well dwarf the music and movie industries combined in global revenue and new-release games offer lighting effects and texture detail that make you forget you’re in a game and not a movie. But there’s always something that tugs us back to retro gaming – the blocky graphics corny 8-bit sound and

Motor control is becoming the power industry’s fastest changing technology area. The reason for this is the requirement to improve energy efficiency from the millions of motors which are used in our homes, factories and cars. New developments in motor controller design, current sensing and control algorithms will be needed if new and more stringent
New energy efficiency rules will change motor control design Continue Reading
Several years ago when I started messing around with Arduino and building my own weather station, I bought a few XBee radio chips with the idea of setting up some more remote sites without having to run wires out to the sensor stations. I spend several frustrating hours trying to get the radios to talk

Standard Arduino boards use FTDI’s FT232RL to interface with computer’s USB port. Since FT232R is just a USB to UART converter, it is possible to build an Arduino compatible USB interface using other USB to UART chips. One such alternative is Silicon Labs‘ CP2102. I particularly like this USB to UART transceiver because very few

The Linux Shell is a command-line interface for controlling the Linux system. Commands entered here can, for instance, install software, manipulate the file system, or access debug messages. If using Windows, we recommend installing Putty, a program that enables to SSH and establish serial communication. SSH is a widely used protocol for accessing Linux shell

If you’re like me, every morning before you leave for work you wonder whether you should wear a jacket before heading outside. You might not have time to check outside your front door, but you always have time to check your iPhone! :] The problem is, standard weather apps tell you about the temperature in
