Soil Moisture Detection System
A Soil Moisture Detection System using Arduino, a soil moisture sensor, and a buzzer that sounds an alert when soil moisture is detected.
Description
The Soil Moisture Detection System is designed to monitor soil moisture levels using an Arduino and a soil moisture sensor. When the soil moisture sensor detects moisture in the soil, it sends a signal to the Arduino. The Arduino processes this signal and activates the buzzer to produce a sound alert, indicating that the soil has sufficient moisture. This project is useful for smart irrigation systems and plant care automation.

A Traffic Light Signal is an electronic project designed to manage vehicle and pedestrian traffic at intersections. Using Arduino, LEDs (Red, Yellow, Green), and an LCD, the system simulates real-world traffic light behavior, displaying signal changes with appropriate timing. This project demonstrates traffic management, embedded system programming, and microcontroller-based automation.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.
