A complete Arduino UNO learning kit built around RFID. Every part in the box works with the UNO board included, so a beginner can go from blinking an LED to an RFID door lock, a keypad safe or a digital clock without buying anything else.
The kit covers the four things most Arduino projects are made of: inputs (RFID, keypad, joystick, buttons, sensors), outputs (stepper, servo, relay, buzzers), displays (LCD, dot matrix, 7-segment) and timing (real-time clock). Learn each one on its own, then combine them into real projects.

Every project is built from the parts in the box.
Scan a card or key tag: the relay switches, the buzzer beeps and the LCD shows access granted or denied.
Type a 4-digit code on the keypad and the servo turns the latch.
RFID card first, then a PIN on the keypad, with messages on the LCD.
Use the remote buttons to switch LEDs, move the servo or turn the stepper.
Move the joystick and the servo follows: pan, sweep and hold.
Turn the potentiometer to set the stepper motor speed; a button reverses it.
Date and time from the DS1302 on the LCD, kept by its own battery.
Four digits on the 4-digit display, started and stopped with the buttons.
Shake the tilt switch and roll a number on the single-digit display.
Messages and animations scrolling across the 8x8 dot matrix.
Drive eight LEDs from three pins: chasers, bar graphs and patterns.
DHT22 temperature and humidity on the LCD, updated every few seconds.
Compare the DHT22 and the LM35 temperature sensors side by side.
The LDR measures room light and switches an LED on when it gets dark.
Clap twice and the sound sensor switches the relay on or off.
The water level sensor sounds the buzzer when it gets wet.
Move the box and the tilt switch sets off the alarm.
Play tunes and tones on the passive buzzer.
