Tips For Sampling High Speed Analog Signal in Arduino/Microcontroller

In many Arduino projects, we need to sample high-frequency signals such as an audio or equivalent signal. Think about a situation we want to sample the 50Hz AC signals and want to see the signal in Arduino serial plotter in real-time. In such cases, we make a few common mistakes that can be easily avoided …

Multiplexing Serial Port for Arduino and Microcontroller Project

Background Story : A few years back I have a project related to the IoT data logging system. In that project, I used SIM800L for internet connectivity and RS480 bus used for communicating with the sensor nodes. I used an atmega328 microcontroller to develop the product. I faced one problem: I needed 3 serial ports …

Hardware Implementation of AM Radio Transmitter and Receiver

For long-distance data transfer, the first condition of the signal power has to be enough strong. The voice signal frequency is almost below 3400Hz signal which has no good enough power to transmit long-distance. Amplitude modulation (AM) is a modulation technique in which the amplitude of a high-frequency sine wave (usually at a radio frequency) …
