The Arduino is something that has been experiencing exponential growth in recent years amongst many technical hobbyists because of its versatility in electronics projects. It pragmatically acts like the brain of any system and allows for the communication between inputs and outputs. The ADXL345 is an example of something that can be combined with the Arduino to create a powerful platform for automation design.
Because of the variety of Arduino boards, such as the Arduino MEGA 2560 or the Arduino UNO, there is a wide selection of projects to choose from for beginners and veterans alike. Once the basics of electronics engineering are understood when working with this microcontroller, things like the LM555\’s Schmitt trigger and L293D can be incorporated for more advanced projects.
A pulse width modulation signal produced the Arduino\’s crystal oscillators can be monitored on an oscilloscope. The Aktakom oscilloscope is a great hobby oscilloscope for students to use for this purpose because it is very cost-effective yet produces reliable results. This oscilloscope also has very large screen for digital signal processing and analysis, but it definitely helps with viewing the properties of different AC signals as well.
When things like the L293D motor driver chip are used along with the AVR-based microcontroller, more advanced programming techniques are often required. Because the AVR is programmed in C, many turn to their knowledge of this powerful programming language to amplify their projects. The internet offers a great wealth of tutorials regarding programming the AVR and using it with the LM555\’s Schmitt trigger, for example.
A Schmitt trigger in the 555 timer is what allows for this IC chip to be used as a signal generator. Because of the threshold and discharge pins on the LM555, a signal generator can be created using the Schmitt trigger which simulates that the Arduino does already by itself. Because the Arduino has all of the LM555 features and Schmitt trigger capabilities already built it, most people do not build a 555 timer circuit for practical purposes but more for the fun of it and for educational use.
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.
