I made many amplifiers and preamplifier project in past. But due to the continuous demand I have some new Ideas about amplifiers. But all of them are half without a proper preamplifier circuit. Because preamplifier not only boost the signal but also arrange low and high pass signal on different output channels. Looking into the…
Hello guys, I am making amplifier circuits and controllers for a long time. But there are some issues with big amplifiers, need high power supplies, big heatsinks, dual channel power and low output. Even we need a big PCB and other combinational modules for controlling bass, treble and subwoofer at all. These become very messy,…
Hello guys, today in this tutorial we have MAX30100 pulse oximeter sensor. We will pair this sensor with our Arduino and check the operation. This will be a simple project and you will get the circuit diagram and code here below. In these types of sketches most of the work is done by libraries itself,…
