Controlling the Movement of a Robot with Legs

In this article by Richard Grimmett , author of the book  Raspberry Pi Robotics Projects - Second Edition , we will add the ability to move the entire project using legs. In this article, you will be introduced to some of the basics of servo motors and to using Raspberry Pi to control the speed and direction of your legged platform. Even though you've learned to make your robot mobile by adding wheels or tracks, these platforms will only work well on smooth, flat surfaces. Often, you'll want your robot to work in environments where the path is not smooth or flat; perhaps, you'll even want your robot to go upstairs or over other barriers. In this article, you'll learn how to attach your board, both mechanically and electrically, to a platform with legs so that your projects can be mobile in many more environments. Robots that can walk! What could be more amazing than this? In this article, we will cover the following topics: Connecting Raspberry Pi to a two-legged mobile platform using a servo motor controller Creating a program in Linux so that you can control the movement of the two-legged mobile platform Making your robot truly mobile by adding voice control

Develop a Digital Clock

In this article by Samarth Shah , author of the book Learning Raspberry Pi , we will take your Raspberry Pi to the real world. Make sure you have all the components listed for you to go ahead: Raspberry Pi with Raspbian OS. A keyboard/mouse. A monitor to display the content of Raspberry Pi. If you don't have Raspberry Pi, you can install the VNC server on Raspberry Pi, and on your laptop using the VNC viewer, you will be able to display the content. Hook up wires of different colors (keep around 30 wires of around 10 cm long). To do: Read instructions on how to cut the wires. An HD44780-based LCD. Note; I have used JHD162A. A breadboard. 10K potentiometer (optional). You will be using potentiometer to control the contrast of the LCD, so if you don't have potentiometer, contrast would be fixed and that would be okay for this project. Potentiometer is just a fancy word used for variable resistor. Basically, it is just a three-terminal resistor with sliding or rotating contact, which is used for changing the value of the resistor.
