Serial LCD Module

In most electronic systems, it is necessary to provide information in the visual form for a convenient user interface. The most commonly used displays in electronic systems are LED, LCD and TFT. Amongst these, an LCD display is the most cost-effective solution as it can display alphanumeric characters along with special user-defined symbols. It also contains an integrated controller which frees up the main ...

Signal Generation with MATLAB. Example of DTMF in telephony

In mathematics a signal is a real function of a real variable f(t). In electronics it represents the evolution of a voltage (or a current) over the time and depends on the performances of the stage of the amplifier. Through a memory buffer, samples move to a digital-to-analog converter that produces a voltage signal, after an  amplification stage that can limit the generation of the signal. A possible analy ...

LM2596 DC-DC Converter Module Testing

LM2596 based step-down DC-DC converter modules can be bought on eBay quite cheaply for around a dollar each. But how do they perform? Is it safe to use it to power your design? Let’s find out. According to TI’s website, these LM2596 step-down (buck) regulators are sold for $1.8 each for a quantity of a thousand. So how a finished converter could be sold for just above a dollar each is quite a mystery to me. ...

Writing a python module to simulate a LCD

So recently I got a Raspberry pi and a 16x2 character LCD screen , I thought , lets make a simple game that can be played on the lcd. my first instinct was to code directly for the lcd on the pi , but as I started coding I realized that the clutter of having the lcd connected wasn't really necessary while i am programming the game's logic . I decided to make a python module that gives me the lcd output on m ...

With the ID3LA RFID module it´s possible to read a tag up to 30cm

As we know, RFID module range is expressively depending on a size and shape of the RFID antenna (coil). That´s why the module with a big antenna has a potentially bigger chance to reach a long range. This is exactly a case of the ID3LA module – working in a wider operating voltages range (2,8-5V) than its predecessor – the ID2 module. This enables its usage even with a 3.3V logic and also for example in bat ...
