		+	<h2> ADC arduino </h2>
		+	When working with the Arduino ADC (Analog-to-Digital Converter), it is important to consider that we can only apply voltages up to a maximum of 5V (or 3.3V in specific boards). Otherwise, we risk damaging the board.
		+
		+	Moreover, and Arduino UNO or the Arbotix Board have a 10bits ADC resolution.
		+	This means that the 0 to 5V resolution are converted to 0-1023 value.
		+	Therefore a 5V equals 1023 while 2.5V corresponds to to 512.
		+
		+	In most of the boards, inputs A0 to A5 can be used as analog inputs, and the function to read it is:
		+
		+	<pre>
		+	int value = analogRead(pin);
		+	</pre>
		+
		+	where <i>pin</i> corresponds to the pin where we are reading the signal (e.g. A0, A1,...) and value is the return value between 0 and 1023.

		+	<h1> Analog-To-Digital Converter (ADC) </h1>

		+	An Analog-to-Digital Converter (ADC) is a device or circuit used to convert analog signals into digital values that the microcontroller can process. It enables the measurement of continuous signals, such as temperature, light intensity, or voltage, allowing for interaction with the analog world.

−	~~<h1> EMG </h1>~~	+	The ADC operates by sampling the analog input at specific intervals and converting the measured voltage into a corresponding digital number. This conversion is typically controlled by the microcontroller’s internal clock, though external sources can be used for precise timing.
