If you’re at all interested in electronics, you’ve heard of the open source electronic prototyping platform. If you just heard about it now, you will have fun!
open source arduino hardware design so that anyone can use the plans to build and sell their own boards. Companies that make various boards also offer various starter kits, which usually include an Arduino board (or «Arduino compatible») and all kinds of electronic components: prototyping breadboard, sensors, relays, servo controllers and motors, jumper wires, LEDs … or any combination of them and more.
The official Arduino starter kit is overpriced by over $100 and doesn’t contain too many components. Instead, consider this third-party Arduino-compatible starter kit from Sunfounder, which comes with several LEDs, dials, and other fun stuff. This is one of my favorite Arduino kits. here. If you want to know if working with electronics is something you will enjoy what is 60 dollars?
The Elego UNO Project Super Starter Kit is another well-maintained kit. It also costs less than $60 and you get a good board with lots of quality electronic components.
Most people will be doing regular beginner projects like building a traffic light. traffic light. But you reader.com . You are amazing. So why not let your first Arduino project be amazingly cool? Let’s take a look at 5 different amazing and unique projects anyone can do with the Arduino starter kit. Read all the way to the end to see one device that can be so funny, it’s scary.
Lie detection with tin foil, wire and Arduino
It’s just for fun. You can’t really detect lies with this project. But you can learn about how what we think and feel affects what our bodies do. This is great. This project detects electrodermal activity. You may know this as Galvanic Skin Response (GSR), from the cops TV show.
Everything you need for this is included in the kit, except for tin foil and Velcro. There is a good chance they are already in the house. Basically, you connect the ground wire to the foil, wire the electrode, connect it properly to the Arduino, and add the desired program. The Arduino program is called a «sketch». Then have fun asking your friends questions and see what the device says.
Simple Arduino Battery Tester
Anyone can use a store-bought battery tester, but not everyone can create one. Okay, maybe someone can, if they have an Arduino starter kit. Using an Arduino board, 3 LEDs, a breadboard, a zener diode, and some jumpers, you can build a device that roughly tells you how much juice is left in your battery. Plus it gives you an excuse to say a zener diode. Add this to your next conversation with friends to get an instant electronics loan. Align
If you enjoy doing this, consider adding readings to your LCD module. Then you can get the exact voltage. If your kit doesn’t come with a zener diode, you can get 10 of them for about $7. It never hurts to have a few spare parts. Gives you more chance to say zener diode later.
Homemade Arduino RADAR
One of the great things about learning to build things with Arduino is how it often helps you learn about other technologies. In this case, it is radio detection and ranging. (RADAR).
Using an ultrasonic sensor, a servo controller and a motor, an Arduino board, and some other bits, you can make a radical RADAR device. If you take the time to work the math into the sketch, it can be amazingly accurate with respect to the distance it sees. This project uses another piece of software called Processing. which is very similar to the Arduino app, but is used to visualize the output of an ultrasonic sensor.
Of course, this is a very short range RADAR, but it also looks very cool and will give you many other ideas for using ultrasonic sensors. in other projects.
Playing with snakes on an 8×8 matrix using Arduino
For many people, their interest in electronics came from playing handheld electronic games. . Why not make the game one of your first projects? The classic snake game can be built with the Elego starter kit mentioned earlier. If you’ve never had a flip phone, this is a game where you have to keep from biting your tail for as long as possible. If you’re older than flip phones, no explanation required. Have you received it.
You will be using an Arduino UNO, an 8×8 dot matrix LED display, a shift register component. LCD display 16 × 2, potentiometer 1K 4 buttons, connecting wires, breadboard and power supply. You can find the diagram and code examples here. This is not the easiest project for beginners. but if you’ve already created the beginner projects that come with the kit, you’re good to go.
Arduino EMF Detector aka Ghost Detector
This is the one you were curious about. An EMF detector is a device that senses the electromagnetic force emitted by any electronic device that has power. Ghostbusters claim it can also detect spirits. Seriously, what show with something supernatural on it didn’t use an EMF detector? Nobody. Plus with Ghostbusters reloading soon, this could be a great prop for your Hallowe’en costume Or maybe you just want to see if Great Aunt Martha is really still hanging around.
The first one in the video above gives its results with a single LED. But you could do so much more! You can try the LED panel also shown in the video, or show the EMF counter on a 7-segment display, or make a sound with a piezo buzzer like a Geiger counter. If you’re adventurous, try building in LEDs, an analog indicator, and a piezo buzzer. Once you build the basic version, you can probably figure out the version approved by Sam and Dean Winchester.
You can do that
These are just five really cool Arduino projects for beginners. You are not limited to what is included in the design books that come with some kits. Go online, find things you think you’d like to build. When it comes to Arduino, chances are someone has already done something similar. DIY Community DIY Community — all about the exchange. So many people are more than happy to share how they did it with you. Just return them, making sure you share too. Need more ideas? Check out these 6 coolest Arduino projects.
