LCFesR meter is a precise, wide range meter that can measure inductivity (L), capacity (C), frequency (F) and equivalent series resistance of a capacitor in-circuit (ESR) based on AVR ATMega88PA-PU microcontroller. It can be easily built with homemade one or double-faced PCB and available electronic components. dr. Le Hung, project designer, explained that measurement of […]
This integrated voting system similar to audience poll system on TV game shows, Who Wants to Be a Millionaire. The keypads consist of an ATmega88 microcontroller and a MAX485/DS75176 RS-485 Transceiver. They are connected to a single RS-485 bus using daisy chain topology with CAT5 cables as connector. Keypad nodes are interfaced to the RS-485 […]
The project goal is to built low cost TV Superimposers based on ATmega88 and ATmega48. The device allows you to display numerical data, such as temperature values, or characteristic data, such as short comments about the video feed along with real-time images from a camera. The project is composed of 2 PCB boards, VSP main […]
Remote controlled audio/video switching is not a new concept, but modern microcontrollers allow designers to incorporate functionality that was quite difficult in the past. Specifically, it is now possible using microcontrollers equipped with EEPROM and SRAM to capture IR signals and store their timing data for use as reference profiles that allow the device to […]
