What is an ADC?
Analog-to-Digital Converter (ADC) is a device used to convert an analog signal into a digital signal. Analog signals are continuous in nature and are represented by a range of values, while digital signals are discrete and represented by a series of 0s and 1s. ADC is used to convert analog signals into digital signals so that they can be processed by a microcontroller or microprocessor.
Raspberry Pi Pico ADC
The Raspberry Pi Pico microcontroller has three ADC pins labeled ADC0, ADC1, and ADC2. The remaining two ADC pins are used for measuring system voltage and temperature respectively. The Raspberry Pi Pico has a 12-bit ADC, which means it has a range of 0 to 495.
Project with Raspberry Pi Pico ADC
This project uses a Light Dependent Resistor (LDR) to detect the intensity of light. The analog value from the LDR is connected to one of the ADC pins of the Raspberry Pi Pico. The analog signal is then converted into a digital signal by the Raspberry Pi Pico ADC. The digital signal is then used to indicate the intensity of light as high, medium, or low.
Example Code
The following example code reads the analog value from the ADC pin and prints it on the serial monitor.
Int adc_pin = 0; // ADC pin connected to LDR
Void setup() {
Serial.begin(9600);
}
Void loop() {
Int adc_value = analogRead(adc_pin); // Read analog value from ADC pin
Serial.println(adc_value); // Print the analog value on the serial monitor
Delay(1000); // Delay for 1 second
}
Overview of Raspberry Pi Pico ADC
The Raspberry Pi Pico ADC is an integrated circuit that enables the measurement of analog signals. It is a powerful tool for converting analog signals into digital values, allowing for the development of sophisticated applications. The ADC is capable of measuring a wide range of analog signals, including light intensity, temperature, pressure, and more. The ADC also has a range of features, including a low-noise amplifier, a programmable gain amplifier, and a programmable reference voltage.
Setting Up the Raspberry Pi Pico ADC
The Raspberry Pi Pico ADC can be set up using the Arduino IDE. To do this, first connect the Raspberry Pi Pico to your computer using a USB cable. Then open the Arduino IDE and select the appropriate port. Once the port is selected, upload the code to the Raspberry Pi Pico.
Example Code for Raspberry Pi Pico ADC
The following example code can be used to read an analog signal from an LDR sensor. The code defines three LEDs, which will be used to indicate the light intensity. The code also sets the LDR pin as an input and the LED pins as outputs. The ADC value is then read from the LDR sensor and stored in an integer. Three conditions are then set, which will determine which LED will be lit based on the ADC value. If the ADC value is less than 200, LED1 will be lit. If the ADC value is greater than 200 and less than 700, LED2 will be lit. Finally, if the ADC value is greater than 700, LED3 will be lit. The ADC value is also printed in the serial monitor of the Arduino IDE.
Testing the Raspberry Pi Pico ADC
To test the Raspberry Pi Pico ADC, open the serial monitor of the Arduino IDE. The light intensity message should be displayed. If the analog value is low, then LED1 will be lit. If the light intensity is medium, then LED2 will be lit. Finally, if the light intensity is high, then LED3 will be lit. The ADC value will be read after every 500 milliseconds.

What is Raspberry Pi Pico ADC?
Raspberry Pi Pico ADC is an Analog-to-Digital Converter (ADC) that enables users to measure analog signals in the form of voltage. It is a feature of the Raspberry Pi Pico microcontroller board, which is a low-cost, low-power, and highly flexible platform for embedded applications. The ADC can be used to measure a wide range of signals, from light intensity to temperature, and can be used in a variety of projects.
How to Use Raspberry Pi Pico ADC?
Using the Raspberry Pi Pico ADC is relatively straightforward. To get started, you will need to connect the Raspberry Pi Pico to your computer via USB. Once connected, you will need to install the Arduino IDE, which is a free software development environment. Once the IDE is installed, you can then write code to control the ADC.
Raspberry Pi Pico ADC Tutorial
To get started with the Raspberry Pi Pico ADC, you will need to create a project in the Arduino IDE. To do this, open the IDE and select Create New Project from the File menu. Give your project a name and select the board type as Raspberry Pi Pico. Once the project is created, you can then write code to control the ADC.
The code for controlling the ADC is relatively simple. The first step is to include the necessary libraries. The libraries are included by adding the following lines of code to the top of the sketch:
“`
#include
#include
“`
Once the libraries are included, you can then create an instance of the ADC. This is done by adding the following line of code:
“`
Adafruit_ADS1015 adc;
“`
Once the instance is created, you can then initialize the ADC by adding the following line of code:
“`
Adc.begin();
“`
Once the ADC is initialized, you can then read the analog signal by adding the following line of code:
“`
Int16_t adc_reading = adc.readADC_SingleEnded(0);
“`
This code will read the analog signal from channel 0 of the ADC. You can also read from other channels by changing the number in the parentheses.
Raspberry Pi Pico ADC Example Code
The following code is an example of how to use the Raspberry Pi Pico ADC. This code will read the analog signal from channel 0 of the ADC and print the value to the serial monitor.

Void setup() {
Serial.begin(9600);
Adc.begin();
}
Void loop() {
Int16_t adc_reading = adc.readADC_SingleEnded(0);
