Infrared sensors are a form of distance sensors. They tend to be more susceptible to inaccuracies. This is because they send out infrared light and wait for the light to tell distance. Certain colors, especially black, absorb some of the infrared light and may return a false reading.

The HC-SR04 distance sensor is an ultrasonic sensor that is used for distance measurements.

Parallax’s Ping))) sensor is an ultrasonic sensor that is used for distance measurements.

XBees are a very simple way to enable wireless communication. Using wireless communication will expand the possibilities of a project, and is practically a necessity for a robot.

XBees are one form of wireless communication. They use radio frequency to communicate over long distances (from 100m to over 1500m.) They do have issues transmitting through walls and through obstacles, but that is common to many types of wireless communication.

It is possible to chain Arduinos together in such a way as to get communication between the two. Having Arduino-Arduino communication can be useful for many projects, such as having one Arduino to run motors and having another sense the surroundings and then relay commands to the other Arduino.…

It is one thing to make a GUI and another to make a GUI that people will want to use. Despite the fact that the appearance of a GUI does not really affect how the program runs, it is always prudent to set up GUIs in a way that they could be presented professionally.

Storing data on a computer is a lot like storing things in a warehouse. If you keep track of where you put things well enough, it shouldn’t matter how much stuff you have stored.

Introduction It is often necessary to being to communicate with a robot while it is in use. This can be done simply through a remote control or more complexly through a GUI. The GUI can allow the robot to both send an receive information while a remote control will only be able to send to the…

Introduction Serial communication through USB can be used to communicate between a host computer (like a laptop, or Raspberry Pi), and an Arduino. Doing so allows: Use of the faster hardware of the host computer for calculations Synchronization of multiple Arduinos Use of other information…
