Today, I would like to ponder on a subject of creating some measurement systems, or in more general, embedded systems. There are multiple approaches to make such a system. Let’s consider a few of them — the most popular approaches.
Embedded systems are gaining popularity by the day. Those systems are used in Internet of Things (IoT) but also in more advanced control systems. However, sometimes a need of more sophisticated system is emerging which requires more computational power. I would like to present some architectures of such systems and highlight some features of those approaches.
For quite some time I was experiencing a problem with my router. When the temperature rises behind the window it just starts to freak out. Every once two weeks or so it drops the Internet connection. Local network is still running but the incoming or outcoming connections are terminated. The only solution to this problem is to reset the router or just take out the plug and insert it after a few seconds. However, it requires me to do this every few days to make sure that the connection is good and running. I have decided to automatize the process with Arduino since it was laying around.
Wireless transmission is getting more and more popular. I will try to show you how does it work using coupled receiver and transmitter which are both working on the same frequency (433MHz).
An another project based on Arduino. Here just a glimpse of the mystery box.
I have done a few project based on AVR microcontrollers. Recently, I have given myself a chance to try out Arduino. After my home thermometer broke down I decided to make a new one. Also it had a few drawback which required fixing. After some time I decided to use Arduino and design a shield for it which would enable this board to measure the temperature and display it. So here it is:
