Design with Haptic controller in Cirkit DesignerThe Adafruit DRV2605L VCC Haptic Controller is a versatile device designed to provide tactile feedback through vibrations or motions. It enhances the interactive experience in applications such as gaming, virtual reality, mobile devices, and wearable technology. This component is capable of driving Linear Resonant Actuators (LRAs) and Eccentric Rotating Mass (ERM) motors, making it suitable for a wide range of haptic feedback applications.
The DRV2605L VCC features an integrated library of haptic effects, allowing developers to easily implement pre-programmed vibration patterns. Additionally, it supports I²C communication, making it compatible with microcontrollers like the Arduino UNO.
This circuit is a haptic feedback system powered by a 2000mAh battery, controlled by an Adafruit HUZZAH32 ESP32 Feather microcontroller, and utilizing an Adafruit DRV2605L haptic driver to drive two vibration motors. The system includes a flex resistor for input sensing, and the microcontroller communicates with the haptic driver via I2C.

#include <Wire.h>
#include <Adafruit_DRV2605.h>
// Create an instance of the DRV2605L library
Adafruit_DRV2605 drv;
void setup() {
Serial.begin(9600);
Serial.println("Initializing DRV2605L...");
// Initialize the DRV2605L
if (!drv.begin()) {
Serial.println("Failed to find DRV2605L. Check connections.");
while (1);
}
Serial.println("DRV2605L initialized!");
// Select the ERM (Eccentric Rotating Mass) motor mode
drv.selectLibrary(1);
// Set the haptic effect to play (e.g., effect #1)
drv.setMode(DRV2605_MODE_INTTRIG); // Internal trigger mode
drv.setWaveform(0, 1); // Play effect #1
drv.setWaveform(1, 0); // End of sequence
}
void loop() {
Serial.println("Playing haptic effect...");
drv.go(); // Start the haptic effect
delay(1000); // Wait for 1 second
}
