How to create Schematic library for PCB designing

This Blog is about creating Schematic library for PCB designing in Altium. Schematic designing is an essential part of PCB designing. Firstly you draw a schematic design which is just like a circuit designing on software. This Schematic generates a netlist that is...

Freedom KL02z and 20×4 LCD

If till now you have used only libraries for 20×4 LCD then it will be more difficult to shifted to the another microcontroller if library is not available for new microcontroller. That time you need to know basic working of LCD. After that you can use this LCD...

GPS data.

Hello world 🙂 Welcome to my blog on GPS data. When we connect a GPS transceiver to our computer we get some data in a standard format which is called NMEA sentence, NMEA stands for National Marine Electronics Association. Each sentence begins with a ‘$’...

Simple signal translator using Some resistances

Recently, I was working on the serial communication between two devices and I found that these two devices are not working on same voltages. That’s why the signal generated from one device will not be read correctly from the other device. It means we need a voltage...
