While it is true, Arduino is defined as an electronics creation platform free code It offers both free software and free hardware, and thanks to this, anyone can use its features and adapt them to their needs. Taking into account that it is possible extend these functionalities to the different types of motherboards, kitsArduino-compatible accessories and applications.
For its part, Raspberry Pi consists a single-board computer which exhibits great potential for simplifying user learning and enabling them to perform basic tasks. Considering that its main objective is based on teach computer science in a versatile wayIt also offers the possibility of compile programs to run on it.
Now then, both Arduino , the Raspberry Pi They are categorized as Some very peculiar boards in the world of programming that allow software development so that implement great ideas without needing advanced knowledgeTherefore, in this post, we want to emphasize The best Arduino and Raspberry Pi programming projects that exist so far.
Discover the best projects to program with Arduino on your own
Fortunately, Arduino boards have with all the essential elements to be able to Connect peripherals to the inputs and outputs of a microcontrollerIn that sense, it has the necessary components to connect to a computer. through serial communicationIn addition, thanks to its support for various compatible accessories and applications, Arduino is characterized by its versatility in providing diverse uses.
Among them, the most relevant of all, are the followingCreation of integrated environments, programming apps, Internet of Things-based projects, software development and 3D printing applicationsThus, enthusiasts of the maker world and DIY culture have decided to take advantage of Arduino's remarkable strengths to to implement actions that are of great interest in the world of electronics, mechanics, robotics, home automation, etc..
Therefore, today there are several attractive projects that can be programmed with the help of Arduino, and here we mention the 15 best of them:
Radar for detecting objects
It is considered one of the most thought-provoking projects of arduino, up to this point. Which, basically, refers to a radar that has the ability to detect the presence of objects by means of an ultrasonic sensor that has a 180-degree coverage or rotation and a range of up to 4 metersThis sensor, It is based on an HC-SR04 and it can be obtained for a low price.
In addition to this, the project requires an Arduino board, the IDE associated with Arduinoa servomotor, a breadboard, and jumper wiresOnce you have the required materials, you will need to use a cardboard support to connect the ultrasonic sensor to the servomotor, which will be linked with a screw. Additionally, you will need to Secure the servomotor to the plate using an elastic band..
A smart traffic light
Regarding Arduino projects, One of the most representative examples is the smart traffic light.Therefore, this traffic light, unlike other common ones, offers the possibility of control two traffic lights at the same timedepending on whether there are any cars waiting to cross or not. In this way, the project's objective is based on simulate an intersection with traffic lights that detect the presence of cars and activate or deactivate accordingly.
Therefore, initially, one traffic light will be illuminated with a green light. Thus, as long as there are no cars at the other traffic light, It will also remain in green.But, once a new car arrives at the red light, The latter will be placed in green and the other traffic light will close after a few seconds. In this way, They will alternate with each other always.
Now, when building this project with Arduino, users will need to use an Arduino board. with ATMega328P microcontrollerAdditionally, you will need six 200 Ohm resistors, two 10 K Ohm resistors, and a total of six LEDs (or even more), as well as 2 pushbuttons and a lot of imagination from the amateur maker.
Robotic arm
In this case, Arduino It is openly linked to the world of roboticsWell, it's an arm specially designed for taking any object with the help of tweezers And at the same time, it manages to avoid collisions with obstacles. Thus, it is based on a robotic arm design capable of moving any small object. from point A to point B, detecting any existing obstacle between both positions.
In that sense, if it encounters any obstacle during its journey, the robot will make sure to find an alternative route to avoid a collision and when it stops detecting the object in the path, it will fix in the indicated position so that it can resume movement to point B.
For this, basically, the programming is implemented using the concept of a Finite State Machine (FSM) And with them, it takes advantage of its speed. With these, the main cycle will conclude in a matter of milliseconds. Besides that, each FSM may assess the current inputs to provide the correct outputs so that the program appears asynchronous and can perform several tasks simultaneously.
In addition, in terms of hardware, the following materials or components are required to create the robotic arm:
- An Arduino Nano R3 board.

The automatic opening waste bin
This is another one of the most interesting projects that can be programmed through arduino. Which, It's an automatic garbage robot. Without needing a direct remote control, it can open its lid when it detects nearby trash, and once trash is placed inside, the bin will close after a few seconds. In other words, it has the ability to It detects when someone reaches out to throw away trash and opens automatically..
As for the software, only It requires the use of the Arduino IDE. While, Its hardware components are as follows: An Arduino UNO board, a servo motor (Tower Pro MG996R), servo arms, an HC-SR04 ultrasonic sensor (it can be generic), a UTSOURCE kit of electronic parts, a trash can (any kind you want) and a piece of cardboard.
Among other details, it is worth noting that the code to compile this project from Arduino, It focuses on a range of 50 cm so that the trash can can open once it detects any object within that distance. Additionally, the servo It needs to be at 50 degrees to hit the top lid of the container so that it opens and when three seconds of time have elapsed, It will rotate 160 degrees so that the same closing lid.
Voice-controlled blinds
They are referring to Bluetooth-controlled blinds that They have voice-activated features.This means they function as a voice-controlled system via Bluetooth And so, it's possible to open and close them on demand. In this way, this extremely practical household item is automated.
Fortunately, it's a project Arduino very economical where Only the following components are required to perform it: an Arduino Nano boardThe kit includes a motor controller, an HC-06 Bluetooth module, two 220-ohm resistors, two pushbuttons, two geared motors, and an LED. You will also need wires, a soldering iron and soldering station, a box cutter, a hot glue gun and glue sticks, and cardboard.

Therefore, to build this project, it is necessary to have on hand a 7-segment display, a pulse generator, a 220 Ohm resistor and a 10k resistor (pull down) and an Arduino Uno boardNow, when it comes to programming with arduino, important Be very careful with random numbers Because, if it's not done correctly, it's likely that always get the same sequence or the same number.
A color-based object selector
This is a kind of machine that It has the capacity to organize the number of items you need.specifically according to their color. Thus, this Arduino-based project consists of creating a color classifier with the help of an Arduino Nano board, a pair of servomotors, a color sensor, several jumper wires, a power outlet and the relevant programming from the Arduino IDE.
Initially, the machine will be able to hold the colored objects you wish to segment on its platform attached to the upper servomotor. Then, the servomotor begins to rotate and transports the object to the color sensor so that... This component can detect the toneSubsequently, the lower servomotor rotates to the particular position, while The upper one rotates back until the bowling pin falls onto the corresponding rail.

Sumado a esto, las resistencias serán las encargadas de medir the incident luz in regular intervalos, girando in horizontal sensing thanks to the servomotor used.
Additionally, the following should also be used: Arduino IDE to enter the source code of system. This source code will be responsible for determine that the servo will rotate as long as there is any incident of greater light in one of the resistors, so that the sensors register the same light. Thus, the structure based on Arduino will be able to follow the light trail of a flashlight and She'll show it off as if it were a magic trick..
