Anyways, I've never really used relays before and since i'm using them to control 120v AC devices, I was just hoping somebody could let me know if i've got everything right. in reality I've got a 4 relay module, but I couldn't find a Fritzing part diagram for that so I used the two double modules, which is why you'll see only one ground and 5v input. In the attached diagram I've got two 2 relay modules side by side. If it is helpful or appropriate I can post the website, not sure what the etiquette is for that, so please just let me know. I've borrowed a lot of this from someone else who was kind enough to share their work and have been working at modifying it to suite my needs. I have just completed my first Fritzing diagram on my way to starting my first Arduino project, which will be an automated chicken coop and I was just hoping to get a knowledgable set of eyes on it to warn me if I've done something really wrong and to hopefully answer a few more specific questions. still have to google the definitions of things like capacitors, transistors and transformers just to remember the differences. I get an unregulated connection to my raw power supply, but it isn't tied to the 'On/Off' switch.Hi everybody, just to forewarn you all, complete beginner here. I know I could use a simple Voltage regulator to manage this myself, but having a switched passthrough of the unregulated power supply for other uses would be very convenient.Īs an aside, I did notice that I could kinda get what I wanted by wiring the '+' and '-' connections which were intended as a supply input out to my board. I have a 12V, 2.0A power supply that I would like to have power an LED light strip, but use this board to deliver the stepped down Voltage for a microcontroller. One suggestion I would have that would make this product even more useful would be to somehow add a way to have a passthrough of the power supply's original voltage to the board. I like the fact that you can easily switch between different voltages, and you have a nice convenient power switch on the board. This is a very useful product to more easily get power to your breadboards from a variety of power bricks.
