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...

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...

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...

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...

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...

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 @...

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...

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...
