Top 10 Best Selling Raspberry Pi Boards

Next we show you a list with the 10 best-selling Raspberry Pi Boards of the moment.

Therefore, nowadays, there are different attractive projects that can be programmed with the help of Arduino and here, we mention the best 15 of them:

Radar to detect objects

It qualifies as one of the most suggestive projects of Arduino, Until now. 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 coverage or 180 degree rotation and a range of up to 4 meters. said sensor, is based on a HC-SR04 and can be had for a low price.

In addition to this, the project requires an Arduino board, the associated Arduino IDE, a servo motor, a breadboard, and jump cables. Once you have the required materials at hand, you must use a cardboard support to proceed to connect the ultrasonic sensor to the servomotor that will be linked with a screw. In addition, you have to secure said servomotor to the plate using an elastic band.

A smart traffic light

As far as Arduino projects are concerned, one of the most representative is the intelligent traffic light. Thus, a traffic light that, unlike the other common ones, offers the possibility of control two traffic lights at the same time, depending on whether there is a car waiting to pass or not. In this way, the objective of the project is based on simulate a crossroads with traffic lights that detect the presence of cars in order to activate or deactivate them opportunely.

Therefore, in an initial state, a green traffic light can be observed. So, as long as there are no cars at the other traffic light, will also stay green. But, once a new car comes to a red light, the latter will be placed in green and will close the other semaphore after a few seconds. In such a way, will always alternate with each other.

Now, when building this project with Arduino, users will have to use an Arduino board with ATMega328P microcontroller. Additionally, it is necessary to have 6 200 Ohm resistors, 2 10K Ohm resistors, a total of 6 LEDs (or even more), as well as 2 buttons and a lot of imagination on the part of the amateur maker.

Robotic arm

In this case, Arduino openly links with the world of robotics. Well, it is an arm specially designed to take any object with the help of tweezers and, at the same time, manages to avoid collisions with obstacles. In this way, it is based on a robotic arm project that has the ability to move any small element. from point A to point Bdetecting any existing obstacle between both positions.

In this sense, in case of encountering an obstacle during the route, the robot will make sure get an alternate path to avoid crashing and when it stops detecting the traversed object, it will fix itself in the indicated position to be able to resume movement to point B.

For this, basically, programming is implemented making use of the Finite State Machine (FSM) concept and with them, use the advantage of showing speed. Well, with these, the main cycle will conclude in a matter of milliseconds. Apart from that, each WSF will be able evaluate current inputs to provide the correct outputs so that the program appears asynchronous and can perform multiple tasks simultaneously.
