Comfortable. Not visibly warm (i.e. low power consumption). Assembled from […]
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 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 […]
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 […]
Design Goals DIY Friendly – Something that the Make audience could easily build Improve the reference design – Better measurement resolution, better timing, lower power, non-stop logging Minimal parts count – Lower cost and shorter build time Powered by a single 1.5 volt cell (AA, AAA, N or similar) and optional supplementary solar power Parts […]
Embedded system An embedded system is designed to perform one function with real-time applications. Embedded systems are found in simple devices like calculators, microwave & television remote controls and also in more complicated devices such as a home security and neighborhood traffic control systems. Many Talented people can take the advantages of simple embedded systems […]
Stereo FM band receiver with RDS decoding for mobile applications. Continuous full RDS data output through RS232: RDS PS, PI, TA/TP/TMC, CT, TMC. Full Radio Text supported: 2×64 characters. Raw TMC data output. Low power operation with two AA (HR6) 1V2 Ni-Mh batteries or power supply. Power input range is +2.4V … +3.0V, 50..60mA without […]
Wireless Infrared UART prototype can be built by using two PIC16F876A controllers. One as IR receiver with dedicated Infrared decoder like SFH505A, SFH506 or similar IR receiver IC and other microcontroller as a transmitter via IR LEDs. This is relatively simple design and doesn’t require advance electronics knowledge or programming skills, especially if you are going […]
