Make Your Own Solid State Relay

In this project we will have a look at solid state relays, find out how they work and when to use them and in the end create our own DIY Solid State Relay. Let's get started!

The video gives you all the information you need to create your own Solid State Relay. In the next steps though I will present you some additional information.
