I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree C, which can be interfaced with microcontroller over two-wire serial i2c bus. It has operating voltage range from 2.7 to 5.5v. I’m operating […]

Due to university and work it has been a while since the last post. But I just completed a little project that’s worth posting. Several old 27C256 EPROMS were lying around unused. So I thought about a purpose for them. As I also had some 8×8 LED matrices, a little animated display came to mind. […]

Another update on the CNC. The interfaceboards are etched, soldered and tested. IO / Control Boards Step- and directionsignals are generated by an ATmega32 which is controlled over RS232. This is only for testing purpose. In the final version a PC will control the movement. For more Detail: CNC Update 2 Using atmega32 microcontroller

And now for something completely different: A little robotics project for the weekend. The described robot can be build entirely from model making supplies and materials from the hardware store. Also only very few tools are needed. A metal saw, a drill press, a vice and optionally a tap will suffice. And here you can […]

Arlington, Texas (PRWEB) April 12, 2012 One of the best ways to provide excellent electronic parts, hardware and service is to have the most reliable sources in the world. Perhaps one of the most well respected names in electronic hardware manufacturing is RAF Electronics. Based in America, RAF provides standoffs, spacers, handles & ferrules, male-female […]

Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge. Here, direction is controlled using a two-position toggle switch and speed of the […]

(PRWEB) September 14, 2003 The new CoaxStrip 5400 can perform multiple stage strips on a variety of wire and cable types, from discrete wire to triaxial cable. The maximum cable diameter that can be processed is 11 mm (0.44”) O.D., and the overall maximum stripping length is 40 mm (1.58”). This increased capacity makes it […]

16×2 LCDs are most commonly used display units in microcontroller based projects. I got much information about LCD, LCD commands, LCD initialization etc from the below link and I hope, it will be very much helpful for beginners. For more Detail: 4 bit interfacing of a 16X2 LCD display to PIC16F877A, Atmega16/32 & MSP430
