LM35 Temperature Sensor Interfacing with ATmega32 and LED Display

LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don’t require subtraction of large constant voltage to obtain the required Centigrade temperature. It doesn’t requires any external calibration. […]

Atmega 32u4 Based USB Musical Keyboard

The music keyboard is one of the most common musical instruments. The electronic musical keyboards have been around for a long time. The electronic music keyboards synthesize musical sounds electronically according to MIDI (Musical Instrument Digital Interface) standards. Fortunately, the USB protocol does have provision to implement the MIDI standard under Audio Class Devices. The

Atmega 32u4 Based USB Controlled LED Series

Throughout this USB series, different types of USB devices have been designed and developed. These devices were enumerating with the host computer and then were using Class Specific transfers for further USB communication. Like the Keyboard, Mouse and joystick devices were using interrupt transfers for their operations after enumeration. Similarly, the audio class devices were
