If you are looking for simple ON-OFF remote switch for your home appliance then this InfraRed remote control circuit is suit for it. This circuit allows you to turn on/off your home appliance (lamp, ran, radio, etc) using any type TV, VCD or DVD remote control with range up to 10 meters. The circuit is easy to build and consist of familiar components like IC CD4017 (decade counter) and Infrared receiver module TSOP1738.click for larger image How it works? The 38 kHz infrared (IR) rays generated by the remote control are received ...

This project shows you how to store data into microSD card in files with FAT32 format using microcontroller AVR ATmega32. The MCU receives sensor’s data through internal ADC. You can connect up to 8 different sensors to the system.In this project, Dharmani uses one channel to read temperature value from LM35 sensor and remain channels are used for simply reading voltages and storing them. The data is stored in CSV (comma separated values) format, which can be read using a PC/Laptop with Microsoft Excel or other compatible software. The project ...

The goal of project is to helps people develop the musical skills of perfect pitch and relative pitch. Push buttons allow the user to navigate a graphical user interface (GUI) on a liquid crystal display (LCD). In perfect pitch training mode, a note is played and the user tries to identify the note on an animated keyboard. In relative pitch training mode, an interval is played, and the user selects the correct interval name from a list of possible intervals.The project featured a MIDI input into the microcontroller for users ...
