#42 Build your own I2C Sensor with three Ultrasonic Sensors for Arduino

In this video we will build an ultrasonic sensor for three directions. The device behaves like an I2C sensor.

The knowledge provided in this video includes:

• Ultrasonic Sensors and ATtiny85
• Wire Library (I2C protocol) on ATtiny85
• The I2C protocol itself
• How to debug signals using oscilloscope and logic analyzer
