Arduino development board
Arduino is a simple, easy-to-learn and feature-rich open source platform, including hardware part (various types of Arduino development boards) and software part (Arduino IDE)
The Arduino hardware part can work independently or in coordination with external hardware devices. For example, use Arduino with various sensors to perceive the environment, use Arduino to control motors to drive robotic arms, robots and drones. You can also use Arduino to control colorful LEDs, which not only brings convenience to our lives but also allows us Create with light and color. It can be said that Arduino is like our little assistant, helping us complete cool maker projects after another.
Arduino IDE software is the program development environment of Arduino development board. We have to write the program code in the IDE and upload the program to the Arduino, then the Arduino will perform the tasks assigned to him according to our requirements. The Arduino development language is based on C/C++.
In the Arduino development board family, the Uno development board is the most suitable Arduino development board for beginners. Because it is easy to learn, stable and reliable, the Uno development board is also the most widely used development board with the most reference materials.
Main technical parameters: The
development board is a controller. Program development is based on this, as an indispensable part of the
breadboard. The
breadboard is the socket. When using a small number of external modules, if the connection location of the controller end is sufficient, you can directly connect to the controller without a breadboard; if the controller ports are insufficient, you can consider using a breadboard. The breadboard is introduced below:
Bread The board can be said to be an indispensable and important tool in electronic experiments, but why the breadboard is called the breadboard, it seems that no information on the origin can be found. What's more, the breadboard is because they built circuits on the bread. . . ,,, I personally think that this is pure nonsense.
Simply put, the breadboard is a kind of electronic experiment supplies, the surface is perforated plastic, the bottom has metal strips, and the electronic components can be used without welding after plugging in according to certain rules.
How should the breadboard board be used? Simply put, just plug the electronic components and jumpers into the board full of holes. How to plug it in and how to layout it, we need to talk about the internal structure of the breadboard. Up.
From the above picture, we can see that there are 4 sets of 8 horizontally connected jacks on both sides of the breadboard. These 4 sets of holes are called power holes, which are generally used as channels for power introduction. Each hole is a channel (the 5 holes are connected), this is our main working area, used to insert originals and jumpers.
Why is there a groove in the middle of the breadboard? The design of the partition in the middle is also exquisite.
It indicates that the upper and lower sides are disconnected.
After adding the width of the groove, the distance between the two faces of the groove is just 7.62mm, which is just right to insert the standard narrow-body DIP pin electronic device.
After the electronic device is plugged in. . Because there are a lot of pins, it is generally difficult to remove them. If the pins are violently pulled, it is easy to bend the pins. This slot is just enough for everyone to use tweezers and the like to reach under the device and slowly lift up...
Well, the basic principles of the breadboard are introduced here. The use of the breadboard is creative and innovative, so you can use the breadboard with more practice and more play.
