There are many ways to learn with the Arduino. This little microcontroller provides a great all around experience for young students who want to learn electronics engineering but also for the serious robotics developer. Because it uses an AVR chip for the basis of the microcontroller, it can be programmed in C or in the Arduino version of it in the IDE that comes with it. The IDE can also be downloaded for free.
Those who are heavily involved in robotics engineering have most certainly experimented with microntrollers. Some of us may have transitioned from the Lego Mindstorms Robotics Invention System to more advanced microcontrollers, like the AVR. However, the fundamental principles of programming remain the same. A lot of this is learned in the introductory system such as the Lego Robotics development system.
Since the 555 timer is so commonly used for so many different projects, it is also commonly integrated with the Arduino. The combination of the two allows for some really cool digital signal processing projects, but most just uses the timer feature of the microcontrollers itself. The 555 timer can, however, be used for more than just timing pulses. Its internal Schmitt trigger, or Schmitt inverter, allows for it to be used for an inverter circuit.
Other projects with the Arduino include more basic things for beginners. It is possible to make LEDs light up in different flashing sequences. This is also possible using the 555 timer, but it requires a more advanced understanding of circuit analysis. The UNO is great for beginners because of the price and the project kit that comes with it. It can be purchased online or even at your local RadioShack.
Utilizing it for a combination project involving the pnp transistors can lead to more advanced designs. Because the MEGA 2560 has a beefier processor and more I/O ports, it is no problem to integrate it with Aktakom oscilloscope. Many people have made fully functional and completely autonomous robots using just a MEGA 2560 and what is duty cycle.
The Arduino is an Italian microntroller, but it is widely used around the world. It is available for purchase online, but many local DIY electronics shops are offering it for sale in-store now. Its popularity has grown over the years, and many schools and educational institutions are taking advantage of its versatility. It certainly caters to novices as well as experienced electronics hobbyists.
