An IR sensor determines how far the ping-pong ball is from the edge of the beam. With everything wired to the Arduino, you have a pretty good testbed for a controller. If is common to “tune” a ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

[Clint] was working with the Arduino library, based on the Parallax PING, which uses a single pin ... he also modified the HC-SR04 sensor by removing the on-board pull-up resistor and adding ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Seeing as Arduino is good for controlling motors and sensors, Randy added a PING ultrasonic sensor to the front of the vehicle too. So in addition to driving back and forth, the toy car will now ...

Makers, developers and Arduino enthusiasts may be interested in a new Arduino project created by Reddit, maker “tkuhn” who has decided to create a machine with the sole goal of “keeping a ...
