Sensors and Transducers
https://www.electronics-lab.com/article/sensors-and-transducers-2/
Introduction Transducers are devices that change one kind of energy into another. They can be utilized as an output from an electrical circuit or as an input. A sensor is a device that detects and measures a physical quantity, such as temperature, pressure, or light, and converts it into an electrical signal. In all electronic […]
Digital to Analogue Converter (DAC)
https://www.electronics-lab.com/article/digital-to-analogue-converter-dac/
Digital-to-Analogue Converter (Binary Weighted) The Digital-to-Analogue Converter (DAC) are opposite of the Analogue-to-Digital Converter. It employs a method by which binary digital signals are transformed into analogue signals. With its output (voltage or current) proportionate to the value of its digital input number, DACs transform binary or non-binary numbers and codes into analogue ones. Conversion […]
Analog To Digital Conversion – Performance Criteria
https://www.electronics-lab.com/article/analog-to-digital-conversion-performance-criteria/
Overview In this series of articles, we considered PCM (Pulse Code Modulation) as a method of digital representation of an analog signal. In the PCM method, the samples of the continuous wave are allowed to take only certain discrete values. These amplitudes are then assigned a code, where each code uniquely represents the magnitude of […]
Analog To Digital Conversion – Binary Encoding
https://www.electronics-lab.com/article/analog-to-digital-conversion-part-2/
Introduction In the first part of this article, we considered the two main stages of a PCM (Pulse Code Modulation) system as the widespread A/D (Analog to Digital Conversion) method and we saw how a continuous signal can be sampled in time and then quantized to limited integer levels in amplitude. The quantum levels are […]

ThomasVDD @ instructables.com writes: A while back I built a powersupply from an old ATX PSU, and while it works great, I wanted to step up my game with a digital powersupply. As already said, it is powered by batteries (2 lithium cells to be precise), and it can deliver a maximum of 20 V […]
Homebrew Multimode Digital Voice Modem adapter
https://www.electronics-lab.com/homebrew-multimode-digital-voice-modem-adapter/
Florian Wolters made his own version of MMDVM adapter: During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called the Multimode Digital Voice Modem […]
Wireless digital scale
https://www.electronics-lab.com/wireless-digital-scale/
This is a wireless digital scale using ATTiny85 microcontroller and HM-10 Bluetooth low energy transmitter/receiver: This scale is wireless. It may be useful where you can’t operate a normal scale, due to the weather outside, or if you don’t want to scare birds or other creatures away. With this scale you can weigh them. In […]
