The moment you get a MAX30100 pulse oximeter and heartrate sensor breakout board, you can move on to the process of making your own perfect pulse oximeter. But is making one as easy as you […]
In this primer, we’ll learn how to play an audio file thru Arduino without using any external modules. Here we’re going to use the pulse code modulation (PCM) audio technique with the help of a […]
Some small experiments on a cheapo soil meter I did recently remind me of the nostalgic photodiode BPW34. So, I think this is the right time for a quick review. Well, let me go further […]
Recently, I had the opportunity to test the internal electronics of several popular Router UPS devices. Honestly, most of them are useless products and will make the router sick within days. Oh, that’s another story, […]
Wikipedia says Current Limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to […]
USB-C Power Delivery (PD) is a standard that supports up to 100W of power! My first attempt in using a USB-C power adapter as a power source for my breadboard projects was met with great […]
The theory behind generating square wave is almost a trivial thing! A square wave is a signal that changes between high and low state where the primary requirement is that the on-time (high state) and […]
This post is just an introduction to how Arduino can be used with synthesizers. So, lower your expectations first, this is not ready-to-go do-it-yourself project documentation. Still interested? OK, get ready to move on! What’s […]
RS-485 is a standard serial protocol, with bus topology where you can connect several devices in a very cheap and cheerful way. Here will be explained how to begin your Arduino + RS-485 projects. Okay, […]
PID Controller is the most common control algorithm used for more precise and accurate control of various parameters in industrial automation & applications. Most often these are used for the regulation of temperature, pressure, speed, […]
