ATmega128 LCD Driver using ATmega128 with Proteus Simulation

AVR ATmega Projects, Circuits, How It Works, LED Projects, Microcontroller / Ibrar Ayyub

Introduction This microcontroller project demonstrates how to directly drive a 2-digit 7-segment LCD using the powerful ATmega128 microcontroller without any dedicated LCD driver IC. Based on the well-known AVR241 application note, this project shows how general I/O pins can be used to control LCD segments efficiently. Using Proteus simulation, this setup helps visualize real-time LCD […]

How Futurology Works

How It Works / Ibrar Ayyub

Forecasting Future Trends Futurologists predict likely futures through refined and systematic versions of the same methods we use every day: brainstorming ideas imagining situations (gaming, scenario building) considering the past (historical analysis) gathering opinions (polling) following trends (scanning, trend analysis and monitoring) picturing desirable futures (visioning) Of course, they take a wider view and employ

Meltdown: Thermal Transfer Fax Machine Though thermal paper is still useful for thermal printers of receipts and bar codes, a different kind of thermal method has taken over for most modern thermal fax machines [source: Sems]. Whereas thermal paper allows for direct application of heat to the paper, the thermal transfer method uses a third

How are cell phones cloned?

How It Works / Ibrar Ayyub

Cell phones are complex electronic devices, sensitive to heat, cold and excess moisture. But a cell phone’s sensitivity isn’t limited to extreme weather conditions. Analog cell phones, as opposed to the newer digital phones, can be cloned. This means that someone can tap into your cell phone’s personal identification number and makes calls on the

How Reality TV Works

How It Works / Ibrar Ayyub

Reality Show Structure So, just how real is reality TV? While it certainly varies from show to show, consider this: All of the concepts were created by someone (usually the producer), the people who populate the show were auditioned or hired in some way, and, while the footage may be real, it is usually extremely

What is a speaker tweeter?

How It Works / Ibrar Ayyub

Traditional speakers produce sound by using an electromagnet to move a flexible cone back and forth. They use drivers to help translate electrical signals into physical vibrations so that you can hear recorded sounds. A tweeter is the type of speaker driver that produces the highest range frequency. The other two main drivers are woofers
