Arduino is an open source electronic prototype platform that is convenient to play, which has been sought after by domestic and foreign engineers. Arduino can sense the environment through a wide variety of sensors, feedback by controlling lights, motors, and other devices, affecting the environment. Arduino-based project, can only include Arduino, or include Arduino and other software running on the PC, and communicating between them. Circuit City has many Arduino-based projects, organized 10, first feel the flexible change of Arduino.
1, Arduino and Raspberry Piece Creating Chatbot Speech Control Robot Arm
There are many projects on making robotic arms on the Internet, but they have similar control methods, I feel missing! So we decided to make a robotic arm that can be controlled using a chat robot. If you say "moving to the left" and the arm will move according to your instruction, then it will be!
Hardware design is approximately based on the UARM schematic. It has a 5 degree movement. The servo motor used is 3 mg995 (metal gears) and 2 sg90 (silicon gears). Each servo motor requires a current of up to 1.5A, so the power supply is sufficient.
Arduino UNO is used as a controller with the Raspberry Pi. The function of Arduino is to continuously listen to the serial commands from the Raspberry Pi.
The software section contains the Python script of Arduino code and Raspberry Pi. The connection between Arduino and Raspberry Pi is connected via a serial cable.

2, Arduino nano stepper motor clock
I want to make a clock with the stepper motor controlled by Arduino Nano to indicate an hour, another NANO and step motor indicating a minute. Stepping motors come from RoHS, which is 28ByJ-48 5VDC provided by Banggood or Wish, with approximately $ 3 per price. They are equipped with a control board and jumper that can be connected at any time. The connection is very simple, just follow the instructions in the step motor example.
The only necessary change in the stepper motor control file is the delay time in the loop function. A small motor start and hour motor latency for a micro motor start and hour motors are used. To adjust the meter, you may have to adjust the delay time based on the motor variability.

3, linear power supply for Arduino project
Every time everyone needs a power supply to support their projects. People like me use ordinary mobile chargers, some people like to use 9V batteries, very few people use LIPO batteries. But I have a better way! Why don't we do your own power? Even if it is cheap than the traditional mobile charger, it has greater flexibility. Today we will make a very small and cheap power supply, which will provide 5V output, but we can easily get 12 or 9V by replacing only a small amount of components.

4. ARDUINO-based smart home system
System functions:
Developed with a wit cloud platform, create a data point on the Hous Cloud platform, and then develop its MCU code and App code twice. Finally, the App will get the temperature and humidity of the smart home, and can remotely control the fan and humidifier in the smart home.
Connection relationship:
The TP-LINK router connects this router through the network cable, the WiFi module connects this router: account Arduino, password 12345678.
Mobile phone connects this router network / other wireless network / usage traffic, open the app to control smart home control. (Later, it directly constitutes a local area network for control, and the data is not uploaded to the mobile phone, so the phone can only connect to router network Arduino to control)

5, Arduino Bluetooth camera (ABC)
I want to exchange data between Android phones and Arduino UNOs through Bluetooth. But I want to transfer is more than just a set of characters and numbers, but also pictures.
This is the unique TFT mask of Arduino. I will demonstrate how to connect to the Bluetooth connection between Arduino and Android phones, get pictures from the OV7670 camera on Arduino Uno and transfer them to the Android phone. Then, in contrast, transmit pictures (images from the camera) from the Android phone to the Arduino UNO, and display it on a unique TFT shielding screen.

6, prototype automatic drying line based on Arduino Uno
The working principle of the project is that when the rainfall sensor is hit by the raindrop (high), the DC motor will pull the dress forward (CCW) out of the room and close it, when the rain is not exposed to the raindrop (Low) but the LDR does not detect the light (dark), then the DC motor will move back to pull the clothesline into the room, then the LED will light up, and when the rainwater sensor is hit by the rain (high) and LDR does not Detection light (dark) then the DC motor will move back to pull the clothesline into the room and the LED will light.

7, Arduino + ESP, create weather forecast boxes that can record weather conditions
One is an Arduino pneumometer with a BMP180 sensor, which includes reports of atmospheric pressure real-time, -1H and -3H. These reports are particularly useful in short-term local weather forecasts. The code is taken from the "shelvin.de" website, where the difference between the absolute and relative atmospheric pressure in the "DRUCK_OFFSET =" line in the code. The result is displayed on the N5110 LCD screen, which also displays the internal temperature.

8, Arduino intelligent guide bar
I saw the blind man on the road on the road, I have to seek help around the people in some cases, so I did this smart guide, this smart bar can help blind people walk safely in the street, do not need any help.

9, DIY Based on Arduino - Pulse induction metal detector
The pulse sensing (PI) system uses a single coil as a transmitter and a receiver. The technology transmits a powerful short pulse (pulse) current through the coil. Each pulse produces a short magnetic field. When the pulse ends, the magnetic field reversal and suddenly crashes, resulting in sharp electric peaks. This spike lasts a few microseconds and causes the other current to pass through the coil. This current is referred to as a reflective pulse, very short, only about 30 microseconds. Then send another pulse and repeat the process. If a metal enters the magnetic field line, the receiving coil can detect the amplitude and phase of the received signal. The amount of amplitude change and phase change indicates the size and distance of the metal.

10. Simple and easy assembled Arduino soldering station
Our soldering station is in standby mode when turning on power. This means that the heater is not connected, you can see the current temperature of the iron hand on the LED display.
To start working, you need a long press button 3 (mode / standby). This station enters the final mode of operation stored in the EEPROM memory.
There are two working modes, named "Class 1" and "Class 2".
Class 1 is a temperature control mode. The required temperature can be set by two buttons 1 and 2 (up and down). Short press the change unit to 1, long press to 5. These values can be changed.
