Sparkfun has a simple-to-use and open source solution for measuring weight and temperature. All you need is a load cell hooked up with OpenScale. You may find a variety of high quality weight sensors to be used in this project on Flintec load cells. OpenScale uses HX711, a 24-bit...

Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for...

joshua.brooks @ instructables.com describes how he build a night light using an Adafruit NeoPixel, ATtiny85 microcontroller, TSSP4038 IR receiver and some other easy available components. I'm giving some workshops in electronics in a few weeks, centered around an inexpensive, but...

Allegro MicroSystems Europe has added a field programmable precision linear Hall-effect current sensor IC with features including a 240 kHz bandwidth, integrated voltage regulator, reverse battery protection, user-selectable ratiometry, and uni- or bi-directional output options. By...

Scott Harden show us how to control the Bus Pirate with python and give us example code. After using the AVR-ISP mkII for years (actually the cheap eBay knock-offs) to program ATMEL AVR microcontrollers, today I gave the Bus Pirate a shot. Far more than just a microcontroller...

Future Cities, a full-length documentary strand from WIRED Video, takes us inside the bustling Chinese city of Shenzhen We examine the unique manufacturing ecosystem that has emerged, gaining access to the world’s leading hardware-prototyping culture whilst challenging...

Online learning of embedded system and electronics in general still bounded, and this is mainly related to the nature of hardware it self. Anyway, efforts for embedded systems training/learning continue to appear especially with MOOC platforms like Coursera and edX. In this blog post,...

Diode or P-channel MOSFET is what you need to protect your circuit from applying reversed voltage, according to a nice video published on Afrotechmods channel. Method 1:Diode The simplest way is to use a diode in series with main power supply. When you connect the power source...
