“Finally got the linebot working reliably. I’ve uploaded 3 images and a movie. I also included the modified Arduino script provided for the “method 1” servos and “V2 Adafruit_Motorshield” I’m using. My sensor board image shows the original 5 sensors described in your “Arduino Robotics” book, but you’ll notice now only the three middle sensors have signal wires, to match the 3-sensor script you provided. “

“I’m always looking out for new ways to add more shields and components to my Arduino, and this felt like a natural experiment, so I gave it a shot: it’s an Arduino, Potentiometer, accelerometer, compass, Lithium Backpack, and TouchShield Stealth wired through a fairly large turkey :)”

"My inspiration for developing this gas gauge was after purchasing a new car (Scion Xa) and wondering what MPG I was getting. After much research on ODBII protocols, and looking into open source software that already existed I delved into my first Arduino project."

"Today I’ll attempt to teach you a little bit about Shift Registers. These are a fairly important part of Arduino programming, basically because they expand the number of outputs you can use, in exchange for only 3 control pins. You can also daisy-chain shift registers together in order to get even more outputs."

"A few days later it was in my hands. Of course I wasn’t the first person to think of this. This kind of board goes by the name Sanguino and more info about them can be found here: http://sanguino.cc/start. That website has all the info you need to build your own, but I’ll show you how I did it with basic, cheap components."

"In this open source hardware and firmware project, an LED “Open” sign is built using an ATtiny2313 microcontroller. This is the type of sign that would typically be used in a shop or restaurant to show that it is open for business."

"The first article in this two-part series, Understanding and Implementing the HC-12 Wireless Transceiver Module, uses the HC-12 to create long-distance data transmission between two Arduino Unos."

"In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy."

"Sound is a phenomena that is a result of vibration of materials. Sound is characterized as a mechanical wave that carries mechanical energy. For the transmission of this energy between transmitter and receiver, presence of a medium is necessary. The medium can be solids, liquids or gases."

"To enable easy documentation of pin assignments, I created a couple of ASCII art arduinos; complete with ports, PWM and coms all marked. Simply paste as a comment into your code and marvel at your new found organisation."
