Connections

Now we will connect the Ultrasonic Sensor to the Robot. The sensor and the robot have the following pins:

1. Ultrasonic Sensor Pins:
   1.  VCC
   2. GND
   3. Trig
   4. Echo
2. Quarky Pins:
   1. GND
   2. V
   3. D1
   4. D2

We will start with connecting the ultrasonic sensor with Quarky using the 4 set wire provided in the kit. But, first, make the connection in the following way:

• First, connect the VCC of the ultrasonic sensor with the V pin on the Quarky.
• Connect the GND of the ultrasonic sensor with the Ground pin on the Quarky.
• Connect Trig of the ultrasonic sensor with D1 pin on the Quarky.
• Finally, connect the Echo of the ultrasonic sensor with the D2 pin on the Quarky.
