Smart arrow uses ADI MEMS sensor

Electronics News Updates / Ibrar Ayyub

The ADXL346 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C® digital interface. The ADXL346 is well suited for mobile device applications. It measures the

OLED Interfaced to NodeMCU

LED Projects / Muhammad Bilal

OLED!! What is an OLED? OLED ( Organic Light Emitting Diodes ) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and

DIY SELF-ASSEMBLING 4D PRINTING

Arduino News / Muhammad Bilal

A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to replicate it using his conventional 3D printer. His attempts to make a joint that changes when submerged in the water looked at several

INTRODUCTION TO LORA – SEND DATA BETWEEN TWO ARDUINO USING LORA

Electronics News Updates / Muhammad Bilal

Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the “I” in IoT and could lead to the ultimate failure of the project. Several communication protocols exist, from WiFi and Zigbee to 2G, LTE, and even satellite communications, but each of them is usually

Arduino Based Weather Monitoring System

Weather Projects / Muhammad Bilal

Abstract— Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather generally refers to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric

DRIVING THREE-COLOR E-PAPER PRICETAGS WITH AN ARDUINO

Arduino News / Muhammad Bilal

ePaper pricetags are becoming popular parts in the hacker community as a cheap way into tinkering with the technology. [Aaron Christophel] got his hands on a 4.4″ model with red, black, and white colors, and set about programming an ESP32 to drive the price tag instead. The protocol the display uses was reverse-engineered by prompting the

MEET THE NEXT-GEN LITHIUM-SULFUR BATTERIES

Electronics News Updates / Muhammad Bilal

What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This radical improvement comes from using sulfur cathodes rather than graphite in lithium-ion batteries. Sulfur
