examples
- the power to choose
In the previous example, you can use the general action of power supply and power supply for L298N Ameba Bridge, and the motor, but after this coupled with the camera, general power often cannot load action, here we use 18650 batteries,
18650 lithium ion batteries, the so called 18650, because it is usually the size of the 18 mm in diameter, 65 mm in length, it is often used for power action, flashlight, laptop batteries, etc., the average 18650 battery rated voltage of 3.7 V, but charge when the voltage is depending on the material difference, it should pay attention to safety in use, to avoid exposure to the battery in high temperature environment, when charging, also should pay attention to whether there is a charge or voltage instability phenomenon, the use of detailed specifications, please contact online,
We use 2 18650 batteries, and using series battery pack, the voltage is about 7.4 V, L298N Bridge can usually accept 7 V ~ 12 V power supply, we will be a battery pack connected to L298N,
L298N with an additional 5 v power supply output, we can use the 5 v power supply,
- connection
Change the power supply and add Camera connection below
- download the library and perform
Please download the AmebaMotors 1.0.3 version of library:
https://github.com/ambiot/amb1_arduino/raw/master/Arduino_libraries/AmebaMotors-1.0.3.zip
After downloading, refer to the Arduino's official website teaching articles will zip file library join Ameba:
https://www.arduino.cc/en/Guide/Libraries#toc4
If already downloaded before AmebaMotors version 1.0.1, first remove the previous version, its location can be in the "File" - & gt; A Sketchbook "Preferences", in the choice of the location, the location is the place where Arduino IDE default placed the sketch with the library, the graph below, it in "D: \ workspace \ Arduino", would be the location of the library "D: \ workspace \ Arduino \ libraries \ AmebaMotors", please delete the library before installing Ameba Motors version 1.0.3
Then open the paradigm, "File" - & gt; "Examples" - & gt; "AmebaMotors" - & gt; "Car2wd_mobile_plus_uvc,"
Modify before operation steps are as follows:
1. Upload code: this time we first upload code to Ameba
2. Connection: the image in front of the wiring way,
3. The mobile phone to download the app: directly by the following link to download: https://www.amebaiot.com/wp-content/uploads/2016/03/Car-Remote-2.2.apk_.zip
Support UVC version is 1.1, please confirm that the current version
4. Connect the phone Ameba: enter the "Settings" - & gt; "Wi-fi," found in the list of ssid ssid "mycar", after click will be required to enter your password, please enter the password "12345678", and then confirm the attachment, because the Ameba is not connected to the Internet, so some Android phones will popup message said there was no network capacity, and even break even to other ssid automatically for you, please note that is properly connected,
