Arduino is an open source electronic prototype platform that is convenient to play. For beginners, it is very easy to master, and there is sufficient flexibility. Arduino is more than just the world's most popular open source hardware, but also an excellent hardware development platform, but also the trend of hardware development. With Arduino, we can easily create a lot of interesting electronic design, organizing 8 open source programs on the Circuit City, play together.
1, play Arduino, technology house to build Arduino alarm clock
My project is an Arduino alarm clock. I really want to know if I can only use the Arduino board and the RTC production alarm clock. At first, these numbers only appeared on the serial port display because I hardly let the liquid crystal display light. I want to go step by step in this process so that I can fully understand what happened.
Details of this project, I have organized in an attachment, interested or demand, for reference only!

2, open source project: Arduino controlled elast ball machine, including Arduino code
The project uses laser jumpers, solenoids, and vertical components to assemble Arduino to control the ball. The solenoid is used to push the push the ball around the venue. The goal is composed of a "basket" that keeps the ball. Once the ball enters the target, the laser stumbling line will automatically trigger the solenoid to make it back to the game. When the ball is popped up from the target, the ringtone is ringing.

3, Arduino bionic mechanical fish
Test the robot before entering the water, you must carefully check each mechanical and line connections. Move the fish and control, and ensure that the two sensors provide signals to Arduino. Using a multimeter measurement its output voltage: Signals should be high if there is no obstacle, make sure the voltage is at least 5.5 V.
At this point, we have prepared waterproof robots: There are many solutions, we have introduced the robot in a plastic bag (see it with holes in breathing, and sealed with tape). Use the rubber band to keep the bag of the robot to keep the body to keep the servo free move.

4, based on Arduino lie detector
Hey, I want to tell you how to make an Arduino controlled lie meter, measure the different reactions of your body according to the situation you feel or you feel, the coolest is that we can see in the Arduino map. All of this is displayed in the figure.

5, small Arduino cat
My underground rock band reunited after 20 years, I decided to use the Arduino Nano, DFPlayer Mini, speakers, three buttons and a 16x2 LCD display to create a small automatic card with some "click".
For the case where I use Fusion 360. I am attaching to the STL file. The initial idea is to create a singer singer, but I don't have time.
For the LCD display, get the I2C interface, so only 2 signal cables, 5V, and grounding are required.

6, DIY Arduino multi-functional meter
In this tutorial, I will show you how to make ARDUINO-based multi-function meter. This small instrument is a very useful device that shows important information about the electrical parameters. The device can measure 6 useful electrical parameters: voltage, current, power, energy, capacity, and temperature.
The device is only applicable to DC load, such as a solar photovoltaic system. You can also use this meter to make battery capacity measurements.
The meter can be measured in the range of 0-26V, and the maximum current is 3.2a.

7, Arduino retro clock
Build an interactive arcade bedside clock, with a touch screen and an animated ariva number, you can record your choice of the alarm sound.
The project includes a 3D printed case and four separate programs to choose from
1. Arcade Clock - DK Mario, Space Affectioner and Eating Beans Animation
2. Eating Beans Clock - Interactive Animation with Clock Function Eating Beans
3. DK Clock - Interactive Animation DK Game with Clock Features
4. Tumble Ghost - Animation Based on Flappy Bird Eating Beans Ghost
For those who like to revisit the people of the 80s arcade games, there are a lot of fun and a great gift.

8, Arduino LED dice, shake
The scorpion is still a perfect entry project. Everyone is very clear, it is easy to understand.
Almost everything has a ready-made component. It is best to see this when looking for Arduino or Raspberry Pi. Components such as the LED, buttons, and any type of sensors are built on the board, so you can connect and use the GPIO through several lines.
Simple but enough 3D printers are available on eBay, the price is less than 140 euros. Almost all brackets, mounting or housing changes can be created with it.
