| This device is designed to help guitarists tune their instruments with ease and precision. By using a microphone to capture the sound of a guitar, the device can detect the frequency of each note played. If the correct frequency is reached, the device will indicate it, but if not, it will suggest adjusting the note through the LCD screen. | This device is designed to help guitarists tune their instruments with ease and precision.

| In order to tune a guitar, we have to get the sample of the frequency of the chord being played and compare it to the notes frequency we are trying to achieve.

| In loop method we first check for the type of input we have (in which state button is), then if necessary we will change the isAcusticMode value, based on the input we want. Then, we call the function FindFrequency(). If we have a match with one of the chords frequency, we can fine tune it to match the exact frequency by providing helpful instruction(we call the function displayNoteAndTune(). | In loop method we first check for the type of input we have (in which state button is), then if necessary we will change the isAcusticMode value, based on the input we want.

| + | |||
| + | This project was an enjoyable experience, combining electronics and coding to create a guitar tuner. | ||
| + | Building the circuit and connecting the components, such as the LM386 amplifier and the jack, was a rewarding hands-on task. | ||
| + | The code development for frequency detection and tuning was challenging but provided a great opportunity to learn about signal processing techniques. | ||
| + | Fine-tuning the frequency ranges and thresholds for each note required careful experimentation and testing. | ||
| + | Overall, the project offered a fun and engaging way to explore both hardware and software aspects of building a guitar tuner. | ||
