Design with Adafruit APDS9960 Proximity Sensor in Cirkit DesignerThe Adafruit APDS9960 Proximity Sensor is a multifunctional sensor capable of detecting proximity, gestures, and ambient light. It offers a simple yet effective way to add touchless interaction to your projects. This sensor is commonly used in applications such as gesture-controlled interfaces, touchless switches, and user presence detection.
This circuit interfaces an Arduino UNO with an APDS-9930 Proximity and Ambient Light Sensor. The Arduino reads proximity data from the sensor via I2C communication and prints the values to the Serial Monitor.

This circuit features an Adafruit QT Py RP2040 microcontroller interfaced with an APDS9960 proximity sensor, an MPU6050 accelerometer and gyroscope, and an OLED display via I2C communication. It also includes a buzzer controlled by the microcontroller and is powered by a 3.7V LiPo battery with a toggle switch for power control.

This circuit features an Arduino Nano microcontroller interfaced with an APDS-9930 Proximity and Ambient Light Sensor for sensing environmental light and proximity. The Arduino Nano also controls an Adafruit Quarter 60 NeoPixel Ring, likely for visual feedback or display purposes. The sensor communicates with the Arduino via I2C (SDA and SCL connections), and the NeoPixel Ring is driven by a digital output (D8) from the Arduino.

This circuit features an Arduino UNO microcontroller connected to an APDS-9930 Proximity and Ambient Light Sensor for sensing environmental light and proximity, and an Adafruit Quarter 60 NeoPixel Ring for visual output. The Arduino provides power to both the sensor and the NeoPixel Ring, and communicates with the sensor via I2C (SDA and SCL) and controls the NeoPixel Ring through a digital data input (D8). The provided code skeleton suggests that the Arduino is programmed to interact with these components, although the specific functionality is not implemented in the given code.
Open Project in Cirkit Designer| Pin Number | Name | Description |
|---|---|---|
| 1 | VIN | Power supply (3.3V to 5V) |
| 2 | GND | Ground |

To use the APDS9960 sensor in a circuit:
#include <Wire.h>
#include <Adafruit_APDS9960.h>
Adafruit_APDS9960 apds;
void setup() {
Serial.begin(9600);
if (!apds.begin()) {
Serial.println("Failed to initialize sensor!");
while (1);
}
apds.enableProximity(true);
}
void loop() {
uint8_t proximity_data;
if (!apds.readProximity(proximity_data)) {
Serial.println("Failed to read proximity value!");
return;
}
Serial.print("Proximity: ");
Serial.println(proximity_data);
delay(250);
}
This example initializes the sensor and continuously reads the proximity data, printing it to the serial monitor.
Q: Can the APDS9960 sensor work with both 3.3V and 5V systems? A: Yes, the sensor can be powered with 3.3V to 5V, making it compatible with a wide range of microcontrollers.
Q: How can I use the interrupt feature? A: Connect the INT pin to an interrupt-capable pin on your microcontroller and configure an interrupt service routine to handle events.
Q: What is the maximum range of the proximity sensor? A: The proximity sensor can detect objects up to 100 mm away.
Q: Can the sensor detect color and light intensity? A: Yes, the APDS9960 includes ambient light and color sensing capabilities.
