Description

Circuit schematic like in Figure 1 above is Musical Keyboard Using ATMEGA8 with Tune Record, Save and Playback Options. This article aims at developing a Monophonic (Single note) musical keyboard by generating the musical notes frequencies using a microcontroller (ATMEGA8). The project presented in this article is a 12 Key, Monophonic keyboard with the options.

By using a microcontroller with digital outputs, it is possible to generate square waves with the frequencies of musical notes. The 16-Bit timer-counter of the microcontroller is utilized to generate a square wave with desired frequency. The timer counter is operated in CTC Mode (Clear Timer on Compare Match). Each time when a match occurs between the TCNT1 Value and the Output Compare Registers, the Output Compare 1A Pin is toggled. Every time when a key is pressed, the Output Compare Registers of the Timer1 are loaded with a value corresponding to the frequency of the pressed key.
