You'll also notice I've used a dual H bridge L298N motor controller in the diagram, I've only done this because that was the product used in the project I'm attempting to work off of and I haven't purchased it yet so I was hoping someone might let me know if I should be looking for a different controller or if this is appropriate for this project.
One area that I'm especially unsure of is whether or not it is ok to have 3 of the relays controlling 120V AC and the fourth relay controlling 12V DC? Also, I don't fully understand what the JD-VCC terminal is for and whether or not I should be using it since i'm controlling two different power supplies (12V DC and 120V AC)?Īnother concern I have is whether or not I should be using inline fuses and/or diodes and if so, where? or pull up or pull down transistors? 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. Hi everybody, just to forewarn you all, complete beginner here.
