This article is another step forward in learning more about AVR microcontrollers. We have demonstrated interfacing of LCD module with ATmega328 microcontroller, which will help you to learn its basic concepts. ATmega328 is an eight bit AVR (Advanced Virtual RISC) based microcontroller. It is a powerful microcontroller with a built-in internal memory of around 32Kb.

To learn about the power factor measurement, you should have a basic knowledge of power factor. There are three types of loads. Resistive Inductive Capacitive When we apply AC voltage to resistive loads it will not change the current wave form. But inductive loads will force to lag the current waveform and in the case

Xbees are some of the most powerful wireless modules you can find and they’re also very easy to configure and use. The only thing is they cost about Rs.1000 to Rs.2500 depending on the range and other parameters. If you’re like me and only bought the modules without the breakout boards or forgot to buy

his board is a development board on which you can build your projects. It is suited for educational use, experiments or prototyping. The board uses the ATTiny2313 microcontroller with a 20Mhz clock. The board contains the ISP 10-pin connector for in circuit serial programming. It has also a push button reset switch. It has 15
Following my initial design article, and the follow up design article, I’ve put quite a lot of thought into how I can make this Goldilocks Analogue device best achieve my stated goals. Pictured is the new 3rd Goldilocks Analogue Prototype. I’m now working on the 4th Goldilocks Analogue Prototype. The PCB layout has been completed, and we’re talking
