Explore Distance Meter With Big Fonts




Introduction: Explore Distance Meter With Big Fonts

In this simple tutorial, I will show you how to make a distance meter. It uses a ultrasonic sensor to read distance and display it in custom big fonts on a LCD display. It is powered up by a battery, so that you can take it around for a ride. We also plan to put up a case around it and make a kit. How does that sound?
