DIGITAL PANEL METER – VOLTMETER
https://www.electronics-lab.com/digital-panel-meter-voltmeter/
Digital Panel Meter performs digital processing on or conversion and display of voltages, currents, other analog signals, and pulse signals. This project is based on popular ICL 7107 IC, which is analog to digital converter and has been designed to drive 7 segment LED display. The ICL7107 is high performance, low power, 3, 1/3 digit […]
How to use a Serial Voice Recognition Module
https://www.electronics-lab.com/how-to-use-a-serial-voice-recognition-module/
by codebender_cc @ instructables.com: In this tutorial you will learn how to use a voice recognition – serial – module with the Arduino uno board. This module can store up to 15 voice commands. Those are divided into 3 groups, with 5 commands in each group. First we should train the module with voice instructions group […]

LED-based time-of-flight IC for object detection and distance measurement
https://www.electronics-lab.com/led-based-time-of-flight-ic-for-object-detection-and-distance-measurement/
by Lee Goldberg @ edn.com: Although Intersil’s ISL29501 time-of-flight (ToF) signal processing IC doesn’t have anything to do with the lighting applications I normally cover, I felt compelled to bring it to your attention because it’s one of the most innovative LED applications I’ve seen this year. The device requires little more than an external emitter (LED […]

Building the Colossus LED Display
https://www.electronics-lab.com/building-the-colossus-led-display/
by Adam Haile @ maniacallabs.com: The 2014 NC Maker Faire was a huge turning point for Maniacal Labs. It was there that the idea for the AllPixel and what is now BiblioPixel got their start. It’s also where we showed off our first custom-built LED display, the 24×24 LPD8806 matrix. At nearly 24 inches square, […]
Driving LEDs
https://www.electronics-lab.com/driving-leds/
Emanuele @ dev.emcelettronica.com published an article on how to drive LEDs: The LEDs (Light Emitting Diode) are diodes whose basic characteristic is the ability to emit light when they are passed through a current that flows from P to N region. At each recombination between the charge carriers (electrons and holes), on PN junction region, a […]
Arduino – How to use a Force Sensitive Resistor
https://www.electronics-lab.com/arduino-how-to-use-a-force-sensitive-resistor/
by codebender_cc @ instructables.com: In this tutorial you will learn how to use an FSR – Force Sensitive Resistor with Arduino to fade an LED. This sensor is a variable resistor just like a photocell or flex sensor. The resistance changes by applying pressure on it. Arduino – How to use a Force Sensitive Resistor – […]
