RFID Checker base on Embedded Linux
My simple project RFID card checker , real time … , Hello guys! How’s going Today I’m gonna present you my project
The inspiration that made me do this project is nothing , I just want to do it …
The hardware we gonna use in this project contain with
1. raspberry pi zero , raspbian OS(it’s the linux from debian)
2. LCD 4X20 I2C interface
3. RFID sensor PN532
4. Speaker pimoroni speaker phat
5. RTC module DS3231
Solution
What connect to raspberry pi ?
- LCD connect via I2C interface
- RFID sensor connect via SPI interface
- Speaker (just put it on the raspberry pi or make another PCB that can lead to raspberry pi pins )
- RTC module connect via I2C interface
Suggestion to you
If you are new , you want to start some easy project I suggest you to use python for development process first .
The Good point of Linux
Linux is a open source, which mean you can find some of libraries from the internet or repositories of the Linux maintainer .
also , LCD driver ,RFID library , Speaker ,RTC all you can find driver on the internet ,just download and install it .
Methods
- Try to Receive value from RFID first
- Next you have to distinguish the unique numbers among the RFIDs card
- Read the time from RTC module and show it to LCD
- Let the speaker play the sound
The last Step
What you gonna do to make the program run at start ?
In the Linux we have something call systemd , this help to create service to run when the system is completely boot .
Our journey come to an end .
