Philips invented the RC5 protocol for controlling electronic equipment such as CD players, VCR’s and audio amplifiers way back in the 1980’s. The RC5 standard has been adopted and used with great success ever since, which means it is probably the most common IR remote control format in your home today. We have recently been […]

The purpose of this project is to announce: a “new 32-bit microcontroller chip named DREAM-1” aimed at Wearables and the Internet-of-Things; and, Kickstarter campaign to perfect DREAM-1’s micro-architecture and chip design. Highlights DREAM-1 is a Next-Generation, Eco-Inspired 32-bit microcontroller chip for Wearables and the Internet-of-Things; No limitations – powered by Eco-Logic technology: minimal energy, maximum […]

The single character LED sign I had been playing with now has a purpose! Shortly after discarding several ideas of having it as a serial display for PC/Server status, or hooking it up to the internet and a webcam, I came up with an actual useful purpose. The sign can be a clock! I have […]

Vacuum fluorescent display can be a good alternative to a Liquid-crystal displays in some applications. They have a number of advantages over LCD like extended temperature range and excellent contrast in high brightness environment. The main disadvantage is higher power consumption making them less attractive in battery operated devices. In this post I’ll show you how […]

lthough infrared communication might look like the technology of the 1990s, it is still present in a multitude of applications around us. Every time you press the button of a remote control, it is most likely it is using the IR (infrared) technology for transmitting data. The TV remote is the most common example. Air […]

Abstract of that project: Using UART port we can establish serial communication between any devices. Here in my project Serial communication with Pic 16f877 using UART I will show you how easily we establish communication between two devices. In my project we know the pin no 25,26 in PIC16F877 are use as UART. The pin […]

The four channel PMT controller board is a PIC microcontroller based device that communicates with a PC by USB as an HID device and with a PIC-based “hand unit” via PIC-to-PIC RS-232 protocol. These two external inputs (USB and RS-232) send strings to the PMT controller that: Sets the four high voltage levels of the […]

The term Morse Code generator is an ancient language, used to transmit the data or information in the form of a series of ON/OFF buttons. This language can be directly understood by a skilled observer who knows the Morse code without any special devices. Understanding of this language is very difficult for the people. Because, […]

Wouldn’t it be nice to have an internet-connected alarm clock that automatically sets itself, based on your calendar? You would never miss an early appointment, never forget to set your alarm, and enjoy more restful sleep knowing you’ve solved the nightmare of regulating your alarms. An internet-savvy alarm clock could even watch your inbox and wake […]
