Magnetic Field Measurement Using HMC5883 and Arduino Nano
https://www.electronics-lab.com/magnetic-field-measurement-using-hmc5883-arduino-nano/
In this tutorial we are going to learn the detailed working of HMC5883 with arduino nano. The HMC5883is a digital compass designed for low-field magnetic sensing.This device has a wide magnetic field range of +/-8 Oe, and an output rate of 160 Hz. The HMC5883 sensor includes automatic degaussing strap drivers, offset cancellation, and a […]
How to Scroll a single LCD line – Arduino
https://www.electronics-lab.com/scroll-single-lcd-line/
R Jordan Kreindler show us how to scroll a single line on a LCD display. The Liquid Crystal Library has two quite useful functions scrollDisplayLeft() and scrollDisplayRight(). These functions scroll the whole display. That is, they scroll both lines on a 1602 LCD and all four lines on a 2004 LCD. What we often need […]
Fuel-gauge ICs help prevent battery clones
https://www.electronics-lab.com/fuel-gauge-ics-help-prevent-battery-clones/
Maxim’s family of ModelGauge m5 standalone fuel gauges provides SHA-256 authentication with a 160-bit secret key to make it harder to clone battery packs. The ICs also implement the ModelGauge m5 algorithm, which converts raw measurements of battery voltage, current, and temperature into accurate state-of-charge (SOC%), absolute capacity (mAhr), time-to-empty, and time-to-full readings. by Susan […]
Ambient light and proximity sensors sense distances up to 10cm
https://www.electronics-lab.com/ambient-light-proximity-sensors-sense-distances-10cm/
With its APM-16D17-05-DF8-TR8 and APM-16D17-06-DF8-TR8 ambient light and proximity sensors, Everlight aims to save energy and reduce unwanted signals and noises when used in smartphones, tablet PCs, residential smart lighting and digital signage applications. [via] Both series use a specially coated photo diode with an optical response similar to human eyes. They have a common […]
EmbeddedLab introduces us TI’s Tiva C MCUs
https://www.electronics-lab.com/embeddedlab-introduces-us-tis-tiva-c-mcus/
Shawon Shahryiar @ embedded-lab.com introduces us to Tiva C series microcontrollers from TI. The Tiva C series MCUs are high performance ARM Cortex M4F micros. Now what does that mean? Generally speaking the ARM Cortex M series is meant to be used in place of (or simply replace) regular microcontrollers like PICs and AVRs while […]
Inside the tiny RFID chip that runs San Francisco’s race
https://www.electronics-lab.com/inside-tiny-rfid-chip-runs-san-franciscos-race/
Ken Shirriff teardowns an RFID chip used to track the time each runner took to run the race. At the beginning and end of the race, the runners cross special mats that contain antennas and broadcast ultra high frequency radio signals. The runner’s RFID chip detects this signal and sends back the athlete’s ID number, […]
World’s First 1,000-Processor Chip
https://www.electronics-lab.com/worlds-first-1000-processor-chip/
by Andy Fell: A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis, Department of Electrical and Computer Engineering. The energy-efficient “KiloCore” chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors. The KiloCore was presented at the 2016 […]

by aniansh @ instructables.com: Have you ever felt like creating one of those city street time lapses that you see on the internet or recording the blooming of a flower through a time lapse or maybe create a night sky panorama of the milky way drifting in the background? Well, now you can do so […]
Conventional Flow vs Electron Flow Explained
https://www.electronics-lab.com/conventional-flow-vs-electron-flow-explained/
“baldengineer” explains which way the current flows. A couple of weeks ago I wrote about four current flow direction myths. As a follow up to that popular post, I decided to dedicate this month’s AddOhms electronics tutorial video to Current Flow. In episode #19, I tackle the question of which way does current flow. You […]
