    How to: Breadboard If you watch our Youtube channel you probably know that I use a breadboard to test different circuits. I find this method very simple and easy to use when you need to test a project before making the PCB and solder the components. You can watch this short video where I am trying to explain how to use the breadboard, what is...
    Common Types of Relay You can choose from a wide range of relays but do you know what type to use in your project? Well, sometimes is hard to choose, especially if you’re not sure which model you need or how a specific one works. In this article we will learn about different types of relay and what to use in you circuit to get the desired...
    Reed Relay The reed relay consists of a switch with magnetic contacts that move under the influence of an external magnetic or the induced field from its solenoid. They have faster switching speed compared to the electromechanical ones but their switching current and voltage is lower mainly because of its contacts thickness. As you can...
    Double Pole Single Throw DPST Relay The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. We have 2 scenarios depending on the type of relay without voltage on coil: with a NO the loads will be OFF because the current cannot flow with a NC the loads will...
    Double Pole Double Throw DPDT Relay The DPDT relay (Double Pole Double Throw) is quite interesting and can be used in various scenarious, including for changing the direction of a motor as you can see in the picture below. It has 2 terminals and 4 connectors and you can look at the DPDT relay as the equivalent of 2 Single Pole Double Throw SPDT relays. Change...
    Single Pole Double Throw SPDT Relay The Single Pole Double Throw SPDT relay is quite useful in certain application because of its internal configuration. It has one common terminal and 2 contacts in 2 different configurations: one can be Normally Closed and the other one is opened or it can...
