Arduino Projects

TM1637 Display Project, or lab_1 demonstrates how to use a TM1637 4-digit 7-segment display module with an Arduino. The display shows various sequences of numbers and characters using custom-defined segments.

Temperature and Humidity Display Project, or lab_2 uses an Arduino, a TM1637 4-digit 7-segment display, and a DHT11 temperature and humidity sensor to display temperature in Fahrenheit and humidity in percentage on the 7-segment display.

Keypad and LCD Menu System, or lab_3 uses an Arduino, a 4x4 matrix keypad, a LiquidCrystal I2C display, and EEPROM to create a simple menu-driven system.
