DEVICE_TOKEN = '__YOUR_DEVICE_TOKEN__' Run the code. sudo python3 attendance_system.py Go to Cloud4RPi, add a new control panel named project5 and add 2 widgets (text and chart widgets) via the Add widget button.
Page 122 SunFounder RasPad 3 Open it with the following command. sudo nano attendance_sheet.2021.06.28.csv In this way, you can read the punch-in records of different time periods. On the left is the ID of different MFRC522 RFID modules, and on the right is the time of punching in.

If the camera screen appears it means that the camera is installed successfully. Otherwise the FFC cable needs to be unplugged and plugged in again.
Page 227: Gpio Extension Board
SunFounder RasPad 3 8.2 GPIO Extension Board Before starting the project, you ﬁrst need to know more about the pins of the Raspberry Pi, which is key to the build circuit. The pins of Raspberry Pi have three ways to name them. They are wiringPi, BCM and Board. Among these naming conventions, the 40-pin GPIO Extension board uses the naming convention BCM.
Page 228 SunFounder RasPad 3 Open the back cover of the RasPad and insert the 40 pin ribbon cable into the Raspberry Pi. Pass the ribbon cable through the available slot on the base of the RasPad, and connect the other end of the 40 pin ribbon cable to the GPIO extension board.

SunFounder RasPad 3 8.4 Use the SSH Remote Control Bash is the standard default shell of Linux, and can be opened on the Raspberry Pi by using SSH. The Shell itself is a program written in C programming language that acts as a bridge linking the customers and Unix/Linux systems.
Page 232 SunFounder RasPad 3 Note: The characters do not display when typing in the password. Make sure to input the correct password. We now get the Raspberry Pi connected and are ready to go to the next step. For Windows Users Windows users can use SSH with the PuTTY application.
Page 233 SunFounder RasPad 3 Click Open. Note: When ﬁrst logging in to the Raspberry Pi with the IP address, there will be a security prompt. Click Yes to continue. When the PuTTY window prompts login as:, type in pi for the user name of the Raspberry Pi. The default password is raspberry.

1. Check whether the power indicator is on, if it does not, you need to charge the RasPad or try a different power source. It is best to use the power supply provided by SunFounder. 2. You might be booting but not getting video output. First, check that your cables are connected properly. Take them all out and reconnect them.
Page 236: About Sleep Problem
SunFounder RasPad 3 9.4 About sleep problem • If your RasPad screen is on but black, this is the Raspberry Pi going into sleep mode. You can wake up by tapping the touch screen, or by pressing the external keyboard or mouse.
Page 237: About The Touch Problem
A. Touch does not work First of all, please check whether the internal cables connection are stable. For the old version of RasPad 3, because the touch will become very strange after an external display, so turn off the touch function.
Page 238: About The Audio Problem
9.9 Fan is too noisy? This is because the fan speed is too high, which was originally done to enhance the cooling capacity of RasPad 3. You can reduce the noise by setting the fan switch on the upper left corner of the mainboard to â ˘ AŸsâ ˘ A ´ Z, but this will reduce the fan speed as well as the cooling capacity.
