Arduino robot with phototransistor mode switch (attempt #1)

Posted on December 21, 2011 by engineerzero

I have a program (aka ‘sketch’) which steers my arduino robot (ie, cheapbot) in a square path. I revised it to use a phototransistor as a mode switch between standby and act (ie, move) modes. Originally, I used the delay() … Continue reading →

Phototransistor as robot mode switch

Posted on December 13, 2011 by engineerzero

Here’s the thing about cheapbot: as soon as you program it, it wants to go. It really needs a mode switch with two modes: one to accept commands, and the other to execute them. Also I want to be able … Continue reading →

Arduino and Photocell

Posted on November 6, 2011 by engineerzero

This is an experiment out of the Getting Started with Arduino book. As you can see, an analog port is connected to a circuit with a photocell (Radio Shack part 276-1657) and resistor (220 ohm). I used a flashlight to … Continue reading →

Budget Arduino Robot Upgrades

Posted on October 20, 2011 by engineerzero

I’ve done some upgrades to my arduino robot. The change that seemed to help the most in the accuracy department was to upgrade the wheels. The potato chip container lids were kind of flimsy, so I replaced them with hard … Continue reading →

Budget Arduino Robot Project

Posted on October 14, 2011 by engineerzero

Given the problems that I was having on using GIRC (Graphical Interface for Robotic Control) with RC toys, I decided to build my own Arduino-controlled servo-driven robot. Aside from the electronics, the body probably cost less than five dollars. A … Continue reading →
