I've just bought the Funduino UNO Robotics Kit, and I have tried out the codes in the tutorial, it worked out great.

I have also got some spare HC-SR04 sensors, but when I tried to replace the sensor in the kit, the robot is not working properly, and it cannot read the distance from the new ultrasonic sensor. I have the new HC-SR04 sensors tested in another board, which worked out fine. So I am wondering what is the possible reason for these sensors not working in our kit?

What does the output in the serial monitor look like with your other sensors? Is a distance printing out?
