Hundreds of projects from beginner to advanced — schematics, code, and videos.
Project showing numbers from 0 to 9 in sequence on a 7 segment display. It teaches the logic of creating numbers by controlling the segment pins.
Project showing numbers from 0 to 99 with a double digit 7 segment display. Teaches bit operations (bitRead) and one-digit-by-ten digit parsing logic.
Counter project that increases, decreases and resets the number on the 7 segment display with 3 buttons. Teaches boundary control and user interactive counter logic.
Project that measures the ambient temperature with NTC thermistor and displays it in Celsius on I2C LCD screen. It teaches how to calculate temperature from analog value with Steinhart-Hart equation.
Setup project to set the time and date of the DS1302 RTC module and display it on the Serial Monitor. Teaches how to use a real time clock module.
Digital clock project showing time, date and day information read from DS1302 RTC module on I2C LCD screen. Teaches RTC and LCD integration.
Project that shows numbers from 0 to 9999 on a 4-segment 7-segment display with SevSeg library. It teaches multi-digit display logic with multiplexing (scanning) method.
Digital clock project showing hours and minutes with DS1302 RTC module and 4-segment 7-segment display. It combines real-time clock data and segment display.
Bomb animation project that counts down on 4 7 segment display, can be accelerated with potentiometer and canceled with buttons. Teaches the use of timer, multiple input control and millis().
Project that alarms with red LED and buzzer when flame is detected in the environment with the flame sensor module, and lights green LED in safe condition. Teaches digital flame detection logic.
Project that measures the gas density in the environment with MQ series gas sensor and alarms with LED and buzzer when it exceeds the threshold value. Teaches analog gas measurement and threshold comp
Advanced security project that uses flame sensor and gas sensor together and alarms with flashing LED and buzzer when fire or gas leakage is detected.
