Proposed Component List¶
Main Final Project Components¶
These are the main components that I’ll need for my final project:
RFID Card Reader and Cards (RC522 RFID Card Reader 13.56MHz)¶
This is the core component for student identification.
Display Interface ( OLED SSD 1306 Module):¶
Provides feedback to students during card scanning.
Microcontroller (Seeed Studio XIAO ESP32C3)¶
USB Battery Pack - 2200 mAh Capacity - 5V 1A Output¶
To make my project portable, I’ll be using a power bank connected to a USB for my power source. I’ve decided to use this one from Adafruit.
Power Supply Unit (USB Power Adapter):¶
The Xiao board can be powered through USB-C.
Software Development Tools (Arduino IDE)¶
I’ll be using Arduino IDE to upload and run my programmes.
Other Basic Components¶
Resistors¶
Resistors limit current flow in circuits, ensuring components receive proper power and protecting them from damage.
Capacitors¶
Capacitors store and release electrical energy, used for smoothing voltage, filtering noise, and timing circuits. I’ll be using them in the form of bypass capacitors.
LEDs¶
LEDs emit light when current passes through, serving as indicators, displays, and lighting sources in circuits. I’m going to have a HELLO LED to let me know if my board is functioning or not.
Update !!!¶
I’ve finished making my final project for real now, and the component list has changed quite a bit. You can refer to it here.
