Bruno Gavand build a simple metal detector using PIC12F683. He writes: The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal...

STMicroelectronics’ LIS2DS12 3-axis accelerometer, LSM6DSL/M 6-axis inertial module, and new LSM303AH eCompass enable always-on fitness-tracking applications to operate longer and record progress more accurately. by Susan Nordyk @ edn.com: These smart sensors help track movement...

Jakub Polonský created this solution to make breadboard prototyping safer for components: adjustable and programmable electronic fuse especially designed for breadboards – a breadboard fuse, or BFuse BFuse: Electronic Fuse for Breadboard -...

ESP8266 has made it possible for makers to develop IoT applications in much simpler and more inexpensive ways. EasyESP-1 is a new ESP8266 prototyping board, specially designed for beginners by Raj from Embedded Lab. With an onboard USB-to-Serial converter pre-installed, EasyESP-1 does...

Silicon Lab’s TS1100 and TS1101 current sense amplifier’s features discussed in this app note. Sensing and controlling supply current flow are a fundamental requirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power...

The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as...

Using standard ICs and open software ecosystem from STMicroelectronics, Samtec has introduced its first Samtec nMode wireless sensor module. The production-ready solution allows engineers to remotely sense and measure inertial, environmental and acoustical parameters. By Graham...

Arduino boards are very useful for beginners to get started with building hardware projects. But at some point, more powerful controller than the Arduino’s 8 MHz one will be needed, featuring faster clock rate, floating point engine, and rich peripherals. As Kris Winer found, the...
