What are interesting Arduino projects?

Finding interesting Arduino projects is not that easy. After all, the choice is huge. Finding an interesting DIY project for children can be a challenge. In addition to age, previous knowledge and interests. But there are other aspects that make an interesting Ardunio project and thatProgramming for children make it a real highlight. These include in particular fascinating special effects such as flashing LEDs. Because visually appealing things are particularly popular with kids. But everyday projects are also particularly interesting for our youngest. Because it is an open secret that children always have the most fun when they see a result and can hold it in their hand.

Would you like to make coding a special kind of experience? How about if you bring the self-built robot to life with your smartphone? Your protégé will not only jam, he will also learn how to use digital media safely. As a beginner, however, you should make sure that you choose projects that are particularly easy to implement. Because the construction of a human robot would surely overwhelm and frustrate you. In the beginning it is sufficient if you control servomotors with an Arduino, light up LEDs or create a text on an LCD display using program code.

As a rule of thumb, the fewer components a project contains, the less can go wrong when assembling. Once you've mastered that, next time you can venture into a more difficult project. How about an exciting project in the field, for exampleelectronics? (see Spahic, 2020). For those who want to start coding right away, see our article on theArduino download Everything you need to know.

1. Bring robots to life

Would you have thought that a robotic arm could be made out of cardboard? The projectArduino robotshows that this is easily possible, because a real robot arm is created with an Arduino Uno, three servo motors and a few other inexpensive components. The associated electronic circuit is relatively simple. However, you need a little skill for the handicrafts. You want to learn more about androids & Co. Then take a look at our courseRobotics kids past.

2. Build the weather station yourself

Observing weather phenomena is particularly fascinating for children. With theArduino weather stationyou can bring the exciting world of the weather straight into the children's room. However, with this exciting project you can record the parameters of temperature, humidity and air pressure. The weather data is processed by a mini computer and displayed on an LCD screen. So you always have a close eye on the weather.

3. Motion detectors for your room

Have you ever got out of bed at night and hit your foot painfully because it was so dark? If so, then the project willArduino motion detector Make it easier for you to go to the toilet at night. Using three movement sensors under your bed, an Arduino Nano registers whether you are getting up and then switches on a colorful LED light chain. In this sea of ​​lights you can see all the obstacles on the way through the children's room.

4. Tinker speakers for your radio

Are you looking for a perfect project for young children? Then it isArduino speakers just the thing. This is a radio that can output various MP3 files via a loudspeaker at the push of a button. The MP3 files are played back by a special chip that has an SD card slot. You could, for example, save songs, fairy tales or radio plays on it. An Arduino Nano takes over the entire control of the electronics. By the way, there are also more complex microcontroller boards, such as the popular Raspberry Pi, that can play music without an additional MP3 chip. If that interests you, then maybe you should also look into the in the futureProgramming Raspberry Pi employ.

5. Build a remote controlled robot car

Remote-controlled cars are especially popular with children. Such a model can be easily implemented with an Arduino Uno and a Bluetooth module. The fact that prefabricated components are used for this project requires little electronic knowledge. A conventional smartphone with a corresponding app, which is available free of charge for Android, serves as the remote control. With theArduino car you are sure to amaze your friends.

6. Install the alarm system

This project requires only a few simple steps and is therefore ideal for beginners. It is an alarm system that registers whether a door is opened or not. Are you wondering how it works exactly? The single-board computer is connected to an ultrasonic sensor and a buzzer, which emits a high-pitched sound when touched. The ultrasonic sensor is attached to the door frame. If the door is moved by a person, the alarm is triggered. With theArduino alarm system Your children's room is safe from any intruder from now on.

7. Build your own solar cell

As you probably already know, solar cells convert light into electricity. The problem with permanently installed solar cells is that the sun moves throughout the day. This means that the angle of the irradiation is not always optimal, which means that the solar cell delivers less electricity. For this reason, there are so-called solar trackers, which always align the device so that the sun shines directly on it. In the projectArduino solar you will get an insight into how you can implement such a tracker yourself with an Arduino Uno, a solar panel and some other components.

8. Stopwatch

Do you want to know if you can run faster than your friends? Instead of buying a stopwatch ready to use, you can buy your ownArduino stopwatch build together with your friends. This project is super easy to implement and only needs a few materials. So there is only one for the creationArduino Pro Micro, an eight-digit LED display and three pushbuttons are required. The stopwatch shows the total time and also the time for a single run. The pushbuttons serve as operating elements.

9. DIY alarm clock

You're always late in the morning, so you always have to run to the school bus. The Arduino alarm clock is just the thing so that you don't run out of time in the morning. With just four components and a few cables, you can assemble a clock with an alarm function very quickly. Since the single-board computer itself only provides a relatively imprecise time measurement, a real-time clock is used in this project. It is a special component that can measure time even more precisely. You will also learn how to control an LCD display, how to read inputs from a 4 × 4 keyboard and how the program or the sketch for this clock is programmed.

10. Build your own polygraph

Are you looking for a real highlight for your birthday? Or do you want to know if your friends are always telling the truth? How about thatArduino lie detector? Lie detectors can certainly not read minds, but they measure certain physical parameters from which conclusions can be drawn about lies or truth. These include, for example, pulse, breathing and skin resistance. If the skin begins to sweat when you hear a lie, it conducts the electricity more easily. In this project, an Arduino Nano measures the skin resistance and indicates a lie by lighting the corresponding LEDs.

Combine different ideas

Perhaps you are so skilled that you have already completed several projects. How about, for example, if you combined two projects? For example, it would be possible to connect the DIY alarm clock with the MP3 radio so that the buzzer does not sound in the event of an alarm, but music is played. That would be a DIY clock radio, so to speak, that only plays your favorite music. Another idea would be, for example, that you could use a solar cell as a voltage supply for the door alarm system, the MP3 radio or the lie detector. There are no limits to your imagination (see Schreiter, 2020).

The Arduino is a great way to learn to code in a fun way. It is worthwhile to start with an Arduino project, because the ease of use and the range of design options allow our little ones to confidently enter the age of digitization. So, what are you waiting for?
