Overview In this series of articles, we considered PCM (Pulse Code Modulation) as a method of digital representation of an analog signal. In the PCM method, the samples of the continuous wave are allowed to take only certain discrete values. These amplitudes are then assigned a code,...

INTRODUCTION - Converting Continuous Signals To Discrete By definition, an analog signal changes continuously over time and it has an infinite variety of amplitude values as time goes on. The best example of an analog physical signal is our voice. Whatever we speak we generate sound...

This is a high-accuracy current sensor project built using ACS37002 IC from Allegro, which is a fully integrated Hall-effect current sensor with 0.85mOhms integrated conductor. A fast overcurrent alert output, programmable gain settings and analog linear voltage outputs are key features...

The project presented here is a low-cost solution for heat management of the heatsink and various equipment that requires automatic control of a cooling Fan. The project is built using a very cheap LM358 OPAMP. LM358 is used as a comparator, and a trimmer PR1 is provided to set the...

Arduino has launched a second version of their Arduino MKR family which features a range of sensors. The Arduino MKR IoT Carrier Rev2 is designed for Internet of Things projects. It provides a range of connectivity options, including Wi-Fi, cellular, and LoRa, as well as a variety of...

The Bosch SensorTech BME688 4-in-1 pressure, humidity, temperature, and gas sensor has replaced the HTS221 humidity sensor and the LP22HB barometric pressure sensor on the MKR IoT Carrier Rev2 board for Arduino MKR boards, and the LSM6DSOX has been replaced the LSM6DS3. The Arduino MKR...

The project presented here is a precision closed-loop LED driver that provides very accurate constant light and can be used for photography, scientific research, and other applications that require an accurate light source. The project consists of light sensor OPT101 and OPA569 power...
