Learn how to connect a PCA9306 Module with Arduino Uno so that devices with different voltage levels can talk to each other safely. <br />Read more : https://circuitdigest.com/microcontroller-projects/interfacing-pca9306-module-with-arduino-uno <br />Arduino Uno works on 5V, but many sensors work on 3.3V. If you connect them directly, the sensor can get damaged. <br /><br />The PCA9306 module solves this problem by converting voltage levels automatically. <br /><br />#arduino #arduinouno #PCA9306 #tutorial #I2C #interfacing
