How to Interface Stepper Motor With Arduino
https://www.electronics-lab.com/interface-stepper-motor-arduino/
This tutorial is going to teach you some basics on using Stepper Motor while interfacing with Arduino and Stepper Motor Driver. Bipolar Stepper Motor is DC motor that move in discrete steps. It has multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, a step […]
ESP8266 temperature logger
https://www.electronics-lab.com/esp8266-temperature-logger/
A ESP8266 temperature logger project from Facelesstech: I decided to use the esp-01 module because I only need 2 GPIO pins since I was using the DS18B20 temp sensor and the WS2812 LED. This made the hardware really cheap and easy to reproduce too. I normally use FTDI boards when it comes to the USB to […]
Iterated-map circuit creates chaos
https://www.electronics-lab.com/iterated-map-circuit-creates-chaos/
Lars Keuninckx @ edn.com writes: The Design Idea circuit shown below is a simple implementation of an iterated unimodal map, reminiscent of the logistic or Verhulst map encountered in the study of nonlinear dynamics. It is useful to show chaotic discrete-time dynamics to students, or as a random number generator. Specifically, the circuit implements: Vk+1 […]
Make Your Own Smartwatch From An Old Cell Phone
https://www.electronics-lab.com/make-smartwatch-old-cell-phone/
Have an old cell phone laying around? Don’t know what to do with it? What if I told you that you could turn that old cell phone into a smartwatch! What I’d like to do for this crazy/ambitions project is turn an old cell phone into a smartwatch. So obviously an old cell phone is […]
New PIC32MM family consumes as little as 500 nA
https://www.electronics-lab.com/new-pic32mm-consumes-little-500-na/
by Clemens Valens @ elektormagazine.com: The new PIC32MM family, currently Microchip’s lowest power 32-bit PIC32 family, features sleep modes down to as little as 500 nA. Filling the gap between the PIC24F XLP and PIC32MX families, the new family also offers so-called core independent peripherals that once initialized can function without intervention of or loading […]
Hall-effect current sensing replaces shunt-resistive measurements
https://www.electronics-lab.com/hall-effect-current-sensing-replaces-shunt-resistive-measurements/
These high speed isolated calibrated current sensors are presented as an effective alternative to conventional shunt based solutions; standard-footprint packaged ICs simultaneously offer 100 kHz bandwidth, high accuracy and crosstalk resilience. By Graham Prophet @ edn-europe.com Melexis (Tessenderlo, Belgium) has added the MLX91210 family of integrated sensors; operating from a 5V supply, the ICs have […]
How To Select an Inductor
https://www.electronics-lab.com/how-to-select-an-inductor/
Sanket Gupta pointed us to his latest article, on how to select an inductor and discuss about the various types of them. Inductors are two-terminal components used for filtering, timing and power electronics applications. They store energy in the form of magnetic fields as long as a current is flowing. Inductors oppose a change in […]
ArduCAM Introduces tiny Raspberry Pi compatible board
https://www.electronics-lab.com/arducam-introduces-tiny-raspberry-pi-compatible-board/
ArduCAM has introduced a tiny Raspberry Pi compatible module based on Broadcom’s BCM2835 Processor, the same chip found in the original Raspberry Pis A, B, B+ and Zero. This module is tiny, measuring only 24 x 24mm and it is compatible with all of the software that makes the Raspberry Pi so popular. It comes with 256MB/512MB […]
VXO – based PLL frequency synthesizer for 7 MHz
https://www.electronics-lab.com/vxo-based-pll-frequency-synthesizer-7-mhz/
Vasily Ivanenko made a VXO-based synthesizer: To make a VXO to mix with a ~7 MHz VCO, you’ll need a crystal that is higher in frequency than the highest frequency you want to synthesize. Some rummaging revealed a bag of 21.4773 MHz crystals that I could divide by 3 to garner 7.159 MHz. To afford a […]
The future of IC design
https://www.electronics-lab.com/future-ic-design/
R Colin Johnson @ edn.com discuss about the future of IC design and the different technologies that can extend Moore Law. Such technologies include 3D memories, superconducting, quantum, neuromorphic and photonic mixed-signal devices. To celebrate 60 years of EDN, we’re looking into the future to predict what advancements will be made in IC Design in […]
