This ATmega168-based digital comb filter built to clean a realtime audio signal. It can remove the ubiquitous 60Hz (50Hz in some countries) hum noise caused by power lines and household electrical wiring. Since the noise is not strictly sinusoidal it is necessary to remove all harmonics of 60Hz, and that is what this filter does. […]

The ATtiny2313-based project is an experiment on the closed loop DC servomotor control system (SMC) by Elm Chan. It can be used for practical use with/without some modifications. The closed loop servo mechanism requires real-time servo operations, such as position control, velocity control and torque control. It will be suitable for implementation to any embedded […]

This little instrument, named as Pico C, can be used to measure capacitances down to fractions of a picofarad. It built based on ATtiny2313 microcontroller. It has range: <1 pF to 2000 pF (guaranteed); 2500 pF possible and resolution: 0.1 pF. To read the result, this low cost C meter comes with 2 lines LCD. […]

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 […]

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 […]
