DS18B20 Sensor Based Thermometer with Nokia 5110 LCD display
https://www.electronics-lab.com/ds18b20-sensor-based-thermometer-nokia-5110-lcd-display/
Hi guys welcome to this tutorial. Today we will be building a simple temperature monitor using the DS18B20 sensor with a Nokia 5110 LCD Display and an Arduino mega. The DS18B20 digital temperature sensor gives a 9-bit to 12-bit Celsius temperature readings and also has an alarm function with nonvolatile user-programmable upper and lower trigger […]

Imitation Fireplace Using Cool Mist and LEDs
https://www.electronics-lab.com/imitation-fireplace-using-cool-mist-leds/
A convincing artificial fire effect for the holiday season, using NeoPixel LEDs, an Arduino UNO, and a cool mist module. The instructions for this are actually pretty simple, basically you just need to get the materials, and put them all together. The only technical part is soldering the wires onto the NeoPixel stick, and uploading […]
Butterfly IQ – Ultrasound Anywhere, Anytime
https://www.electronics-lab.com/butterfly-iq-ultrasound-anywhere-anytime/
Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe), […]

After $5.5 millions collaboration and a lot of work during the past four years of engineers at Imec, the next-generation electrodes called Neuropixels probe were designed to record hundreds of neurons in the brain. Imec is an international nano electronics research center dedicated to build and test powerful new devices for detecting neural activity within the […]
The top 10 crystal oscillators from SnapEDA
https://www.electronics-lab.com/top-10-crystal-oscillators-snapeda/
Elizabeth Bustamante @ snapeda.com lists the top 10 crystal oscillators used today. She writes: A crystal oscillator is an electronic circuit that generates an electrical signal with a very precise frequency. To achieve this, it uses the mechanical resonance of a vibrating crystal made of piezoelectric material. The first crystal oscillator was invented in the […]
