Current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 Op-amp, ½ of  LM358 op-amp used as an amplifier for low voltage  and 2nd 1/2 LM358 op-amp used as comparator which provides over current TTL output, trimmer potentiometer...

Are you an experienced maker who are looking for more advanced Arduino skills to get? Warren Andrews, an experienced engineer and journalist, wrote a new book that walks makers through building 10 outside-the-box projects, helping them advance their engineering and electronics...

IoE era is here since we are able now to add mobile radio capabilities in our applications! The latest incarnation of the cell phone network will offer internet connectivity and possibilities that could only be dreamt of previously depending on your standpoint, and many more...

Michael Dunn @ edn.com has compiled a list of software that most enginners should be aware off. We're living in a golden age of software, where many useful programs are available – for free! Let's survey some of what's out there that just might interest an engineering crowd...

by Max Maxfield @ eeweb.com: A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who — thus far — have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of...

Susan Nordyk @ edn.com: A single-chip 2.6 A driver for brushed DC motors, STMicroelectronics’ STSPIN250 targets battery-powered portable and wearable applications. This low-voltage, energy-efficient driver integrates a power MOSFET bridge and fixed off-time PWM current controller...

by Susan Nordyk @ edn.com The MAX17055 single-cell fuel gauge from Maxim not only eliminates battery characterization, but also keeps SOC (state-of-charge) error to within 1% in most scenarios. With its ModelGauge m5 EZ algorithm, the device provides tolerance against battery...

The 6 Channel RF Remote Controller designed using CC2500 RF Transceiver modules and PIC16F1847 micro-controller from microchip. Transmitter provided with 6 tact switch, 4 Address Jumpers to pair multiple unit so they don’t interfere with each other. Board provided with power LED,...
