Board comparison lab
Compares 5V Arduino and 3.3V ESP32 wiring considerations before adding an RFID reader later.
What you build in this project
Board comparison lab is one focused build from the RFID Access Control Learning Kit. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.
Compares 5V Arduino and 3.3V ESP32 wiring considerations before adding an RFID reader later.
Parts used
Arduino UNO, ESP32, keypad, servo
What to check
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
What you learn
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
What this project uses
Every item is in the kit — nothing extra to buy.
RFID Access Control Learning Kit
All 10 parts in one box, with this project and 2 more to build from them.

One of each part. Packs (resistor assortment, jumper wires) already hold more than a single build needs. Delivery is free on orders AED 150.00+.
More from this kit
Servo latch prototype
Moves a small model latch after an accepted input; not for real door security.
Keypad access demo
Accepts a simple code and gives pass/fail feedback through light and sound.
