TVS diodes protect circuits from voltage spikes. Let's discover what they are and what makes them special!
Building a voltage source for small circuits with a zener diode? Let's explore how this is possible, let's build a shunt regulator.
Today, we are going to build a low voltage alarm using a zener diode and an LM393 comparator.
What can we use zener diodes for? This time, we look at their use as voltage references.
Let's learn more about the second important breakdown effect in zener diodes: the avalanche breakdown.
The zener effect is the dominant breakdown effect in low voltage zener diodes. Let's take some time to learn more about it.
They are a very effective protection against over voltage and reverse polarity. Let's look at how diodes can be used as input protection.
It is a necessary component in many circuits with inductive loads: the flyback diode.
It is used in many products and is de facto the standard rectifier: the full-wave bridge rectifier. Let's discover how it works.
A popular application for diodes are rectifier circuits. Today, we are going to look at a simple half-wave rectifier.
The MAX3010x sensors can do more than just heart rate measurements. Let's do some pulse oximetry.
Our previous approach for heart rate measurements didn't work very well. It's time for a better and more scientific algorithm.
Now that we can acquire data with MAX3010x modules, it's time to apply our heart rate detection algorithm to it.
It's time for some more advanced heart rate sensors. Today, we are going to take a look at the MAX3010x pulse oximeter sensor family.
As promised, we are going to look at another solution for detecting heart beats. This time without using a buffer.
In the last part of this tutorial, we already tried out the KY-039 module. Today, we are going to implement a proper heart rate detection.
Today, we are going to look at a very simple heart rate sensor. Let's discover how it works and how we can measure the heart rate with it.
The LM35 is a cheap and easy to use analog temperature sensor found in many Arduino Kits. Let's find out how to use it.
