Right now, if you like to build robotics stuff or other electronics projects you probably heard of the Arduino and what it can do. This cheap microcontroller is perfect for automation projects at home and so much more. Plus, the programming is super easy when you get the hang of it. Of, course there is the Raspberry Pie and others like this that will be more useful for advanced projects but let’s keep it simple here.
So in this article we’re gonna talk about 5 Arduino Uno shield that I believe can make great projects. The Arduino Uno is basically the most common Arduino board so that’s why I’ll be talking about this one, but there are a lot of other Arduino models and generic ones too so make sure to pick what you need and what fits best your budget.
There are a lot of reasons why you would consider having a internet shield on your Arduino Uno board. Maybe you want to control your project with your phone on your networks or store data.
By example, you could monitor the temperature of your house and store the data on a hard drive or SD card. Also, you could control the lights or heating of your house with your phone or when you are not home. So, it can be really good for home application and so many other things. It’s really just the tip of the Iceberg here.
You can find this one, the Kuman K15 Ethernet Shield W5100 Micro-SD Card Slot for Arduino 2009 UNO Mega 1280 Mega 2560 Nano Duemilanove (with a super long name) at 17.99 CAD and any other generic ones on amazon.com. Sorry if I put the money in Canadian dollar but it’s probably like 14$ US. If you are more into getting the real thing, there is also the Arduino website that you can go directly. Plus, what it’s nice about this shield is that you can put a micro SD card in it to store data directly on it! Here, you can see some nice projects made by people with the internet shield.
When you want to do robots, remote cars or anything that needs motorization, you sometimes need more control over your motors. That’s where this shield comes in. The motor drive shield can drive your stepper, DC or servo motors.
There is this one on amazon.ca the Kuman KY58 L293D Motor Drive Shield expansion. Again, I’m sure you can just write down motor shield drive on Google and you will find one for your country. There is the real one on the Arduino store at 22$ US. There is this video that explain the basics of it:
After that, you can do many projects who need motors, by example here, you have a nice project where you can build a robot who is avoiding obstacles. That can be pretty simple project if you what to start practicing.
This one is pretty simple, it’s simply a breadboard that you can put directly on it. It’s very nice if you need to do quick prototype and test them. I found the RoboJax Prototype Shield With Mini Breadboard for Arduino on amazon.ca but I think there is some even cheaper if you search a bit.
Of course, if you have a breadboard already and you work fine with that don’t buy it. I just think it’s a good way to have everything at the same place for quick sensor or actuator testing.
Simple LCD Screen
For a lot of projects, you will need real time infos to be displayed. For example, you will maybe want the speed of the motors in your projects or maybe create a menu to select different options. I found this model that can do both the KEYESTUDIO 1602 LCD Keypad Shield Arduino, as you can see, it fits on top of the Arduino Uno, it has an LCD screen and buttons. In the video below, you can see a short explanation on how it works even if it’s not the same model.
TFT LCD Screen
Now, if you are fancier and you like the touch feeling you can go with a tft LCD screen that can look really nice on a project. The tft LCD screen is touch and it can be a really nice small HMI for an automation project. There is this model that looks pretty nice on amazon.ca, the Arduino MEGA 2560 Board Module. Again, the video below shows a simple example of what it can do.
Relay for Power
The last of this article is a pretty simple one but that is very useful when you need more voltage on an output in your projects. For example, in our first YouTube project, we are using a linear actuator from the company Progressive Automations.
The actuator is working with 12 V and the Arduino card only provide 5 V. So, it means that we need a relay to be controlled by the Arduino card and then drive the 12 V to the actuator to make it move. So, with this kind of shield you can plug it directly on your Arduino board, make the proper connections and you are in business.
I found this model online the KEYESTUDIO 4 Channel Relay Shield 5V who has four relays that can endure up to 120VAC/3A or 24VDC/3A. That’s pretty decent for a lot of projects. Although, for our project we use an external relay module also find on Amazon, the ELEGOO 4 Channel DC 5V Relay Module. If I had to redo it, I would take the shield for the portable advantage and less wiring to do.
As you can see, by now, you can pretty much find a lot of brands for those shield. It’s a wide market, so just be careful of the quality and find the price that fits you best. Also, you are not forced to buy shield for your projects. You can easily get the job done by buying a module to put on the side. But I think that having a shield that can directly be put on top of the Arduino is a nice advantage for small and portable applications.
Again, thanks for all people following us on social media. If you want to help us in our projects, we have the new Merch there is still the Patreon and don’t forget to subscribe to our YouTube Channel it will be really nice. You can also visit our new forum on the website. Talk to you later guys!
