A triple Channel VFO capable of generating frequencies between 8kHz to 160Mhz using an off-the-shelf SI5351 module.
Motor driven is the key of automation. In this chapter, I try to show how Raspberry Pi control ABB motor Driver by using RS485.
An introduction to the cool new SDR radio!
A very simple FM blocker circuit works within 10 meters of range. Let's build one with theoretical approach.
Timer one is used in this code and using this the Arduino crystal clock is divided into various small parts microseconds are used for freq.
