Analog Devices (ADI) has introduced a quad-channel protector and two multiplexers offering ±55V overvoltage protection (OVP) for precision converters, amplifiers and other components that operate from a voltage of 4.5V up to 36V. According to ADI the ADG5462F quad channel protector, ADG5248F 8:1 multiplexer and ADG5249F differential 4:1 multiplexer offer ±55V OVP in power-on and power-off stages […]

Building a simple and easy microcontroller based robot is always a fascinating topic to be discussed, especially for the robotics newbie enthusiast. On this tutorial I will show you how to build your own microcontroller based robot which known as a photovore or you could call it as the light chaser robot using the simplest […]

WOW! Less than 2 days left and only $4,000 away from our stretch goal! Incredible. Looks like everyone’s going to get a rainbow snap band! Those of you who have shared and upgraded your pledge thank you so much. We really really appreciate it. If you haven’t upgraded to a Family Pack Remember these aren’t […]

Optically isolated parallel port  break out board designed for Hobby CNC, Routers and Motion controller, This Board is an easy solution to drive stepper Motor driver through PC parallel port, The Board is compatible with various CNC software specially made for LPT port data output. The board has been tested with MACH3 CNC software.   […]

We’ve all done it – looked sideways with not a little envy at a range of add-ons for a power tool, and wished that they were available for the one we bought. There is no ’standard’ footprint for a PIC Micro-controller development/experimental board. Vendors have chosen to provide their own ‘take’ in each case, and […]

Fujitsu is sampling a 1Mbit SPI FRAM in an 8-pin WL-CSP device measuring 3.09×2.28×0.33mm which reduces the surface mounting area by 77%, and the device height by 80% compared to an S0P-8 package. The WL-CSP package makes FRAM suitable for wearable and sensor applications which need small device dimensions, extremely low power consumption for maximum […]

The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, […]

Introduction There are many DIY versions of WWVB clock designs available on the web. Commercial “atomic” clocks are inexpensive and widely available, but I wanted to try my hand at designing one to gain insight into WWVB reception and to learn a little about programming a PIC microcontroller. My version is not the simplest available, […]

Melexis is supporting its time-of-flight (ToF) sensing technology with the EVK75023 evaluation kit which accompanies its MLX75023 QVGA (320x240pixels) resolution ToF sensors. This new hardware platform enables implementation of more advanced human machine interfaces (HMIs).Co-developed with BlueTechnix, the EVK75023 is a 130x105x60mm board for assessment of ToF sensing capabilities under challenging conditions, where the detrimental […]
