The Raspberry Pi is powerful computer despite its size. This portable device comes with a CPU based on the Advanced RISC Machines ( ARM) architecture. It runs on reduced instruction set to have a high operating speed. This device is also capable of wireless connections and fast and high memory capacities.
Engineers, electronics, and programming enthusiasts tend to have this useful machine as it allows them to practice their programming skills and be creative in their inventions and innovations. With this pocketable device, users can create various functions such as automation, electromagnetic or sound sensors, and even advanced applications such as machine learning, the internet of things (IoT), and artificial intelligence.
However, despite having this remarkable machine, one still needs to learn coding, especially young people. Coding for kids classes, preferably one-on-one, is a must due to its student-focused benefits that will help children better understand the basics of programming.
Students can voice their concerns and communicate effectively with their instructors during one-on-one instructions. According to some studies, pairing this learning approach with coding brings great results.
Raspberry Pi heavily relies on the coding skills of its user. When you are proficient and confident enough with your basic knowledge of coding and programming, you can freely enjoy the wonders this valuable machine can offer. Below are some of useful projects you can do with your Raspberry Pi.
This one is quite a great starter for beginners. One sensor that can surely detect motion is an infrared (IR) detector. As we know, anything with a temperature above absolute zero expels infrared radiation. This sensor’s main function is to see any changes in infrared radiation on its line of sight. The sensor will be operating well when connected to your Raspberry Pi circuit board, together with some python codes and tuning. Make sure to adjust the delay time and sensitivity of the sensor.
However, the function is not complete when the sensor is the only thing working. This project will be even more functional with a camera and an alarm device. Attach these to the circuit board and add a few lines of code that command to take a picture and set off an alarm.
If needed, an ultrasonic sensor will be a great alternative to one that uses infrared light. This one, on the other hand, uses sound waves to detect space changes. The sensor projects sound pulses and detect their echoes to know how far an object is. Although this costs more than IR sensors, they are proven to be more reliable and efficient in identifying motion changes in the environment.
Wouldn’t it be fun to have your child’s device be controlled over the internet? Then this is the project that is perfect for you. Having a web interface for your Pi will help manage its other functions remotely. This will also be a great addition to your IoT setup.
You can use this feature to command your Raspberry Pi to do simple things, such as turning lights on or monitoring your sensors. Having to type commands and texts to make your Raspberry Pi do its tasks is quite a bummer. Thus, it calls for the need to have a graphic interface that is interactive and easy to navigate.
The small size of this particular device allows for its ideal use in Robotics science. Many personalities in robotics have been using Raspberry Pi to perform their projects effectively in their tasks such as walking, avoiding obstacles, and other sensors. But for the basics, the code only needs commands that can make the robot move in any direction. It can also be programmed to follow visual cues and move only at a certain track. Don’t forget to make a cool 3D-printed enclosure to make your machine even more appealing.
A weather station is another creative way to utilize your Raspberry Pi. Even if this needs quite a lot of materials to make, it assures maximum functionality for the user. The weather station will require enough amount of sensors to be able to measure any disturbance in the environment. You need temperature, humidity, and pressure detectors to collect atmospheric data.
It also includes mechanical sensors such as a rain gauge, wind vane, and anemometer. When these equipment are placed outdoors, make sure that they are enclosed or made of waterproof material to prevent any damages caused by liquid. There are available python libraries online that you can use and modify to your liking for this project.
Music Streaming Device
This one is mainly for entertainment. If you love music, then this project will be engaging for you and your child. Easily set up your hardware with a portable but compatible speaker wired to the Raspberry Pi. Afterward, install and configure the codes that will connect to your favorite streaming app. Do not forget to test the sound quality manually to ensure that it delivers the music optimally. Fit that hardware in a nifty-looking enclosure to match the vibe.
Research on the effects of computational thinking and coding classes on children shows that these sessions improved their logical sequencing and problem-solving skills. Thus, working on a Raspberry Pi would be easier and more productive if the child took these one-on-one courses.Also, using the common coding applications for young students facilitated and encouraged them to develop their passion and interests for experiments. With devices like the Raspberry Pi, they can apply what they learned, and explore deeper into the realm of coding with greater confidence.
