I have built the automatic watering kit for my project but I was wondering if it is possible to implement a timer as well. If so would you be able to provide a code for me to use which I can add to the program as it is my first time using any Arduino products so I don't really know how to program. Thank you for your help.
We are very sorry, we don't have the code for this at the moment. You will need to explore on your own.
Here are some suggestions:
1 An easy way to accomplish your needs is to turn on the solenoid valve and add a delay to the loop. This way, you can water regularly.
2 A more complex way to do what you want is to add a timer.
I have newly bought an Elecrow panel 7 inch display recently,Trying on the tutorials but the
Draw GUI with LovyanGFX
Example is not working and black screen without the error message in arduino IDE,
Please help what was the issue with it.
To help resolve the problem, please follow the steps below:
1 Please verify that the program uploaded successfully If the upload was successful but the CrowPanel screen does not show anything, there should still be messages in the Serial Monitor and Output windows of the Arduino IDE. Please send us screen shots of all the outputs in the Serial Monitor window and Output window for review.
2 Please click on Tools in the Arduino IDE and send us screenshots to check for any configuration issues.
3 Please also send us screenshots of all installed libraries and their versions. Select “Installed” under the Type filter as shown in the example below. If there are multiple pages, please capture each one.
4 . Please make sure the version of esp32 installed is 2.0.14 or 2.0.15, installing any other version will result in the error
5 Additionally, if the hardware version is 3.0, you will need to use the V3.0 code. You can check the hardware version as shown below.
The screen also flickers. The same problem occurs with the code above. Have you guys encountered this before? Is it a hardware issue?

How the module works, I need a library or some way to use it, an example of how to use it correctly is enough

There are three pins labeled “UART” on the bottom of the CrowPi. Which UART port do these connect to?
The UART port can be used for communication, e.g. to connect to a sensor with a uart interface or to connect to a device with a host controller for communication.
“This UART port can be used for communication, such as connecting to a sensor with a UART interface or connecting to a device with a main control chip for communication.”

For password issues, please follow the steps below to resolve them:
(1) Press ctrl + alt +F2 to enter the terminal. If it does not work, change F2 to F1~F7 and try any key that can enter the terminal;
(2) Type startx in the terminal and press Enter.
Crow Note cannot display the Raspberry Pi screen.
Please check: 1 Whether the power outlet is normal or use another outlet 2 Use the power adapter that comes standard with the device 3 After plugging in the power supply, you have to press the power on button in the upper right corner of the keyboard

Unable to restore CrowBot BOLT to factory firmware state, unable to run Python program under Thonny.
Modifying the ESP32 version bit version 2.0.14 allows you to download the arduino program.
You will need to upload the firmware to the esp32 using the Thonny software.
Please refer to the pdf file in the python folder and the following link to upload the firmware:

Connect RFID reader and 4G modem to this display.
Help to see if our customers of this product can connect RFID reader and 4G modem?
RFID readers and 4G modems with i2c interface or serial port interface are both acceptable
Crowbot's remote handles will not be paired with all robots in the classroom. We need instructions or guidance so that each remote handle is only connected to a single robot and that each robot has a dedicated remote handle.
To ensure that each joystick pairs only with its designated CrowBot without interference, you can modify the factory code by assigning a unique set of 4 BLE UUIDs for each joystick-CrowBot pair.[Photo]
Specificly, Please refer to the following information:
1 You can generate unique UUIDs using the following website:
https://www.uuidgenerator.net/
Then, Upload the corresponding modified program separately to the CrowBot and the joystick.
2 To upload the code, please make sure to copy the content inside the "library" folder provided in the Arduino code package (from our Wiki) into your Arduino runtime libraries path. Then follow the instructions in the tutorial PDF included, as shown in the image below.[Photo]
⚠ Important: When uploading the program to the joystick, please make sure to select "ESP32C3 Dev Module" as the board type
