Simple Sound Sensor Circuit with Arduino
This project show how to use sound sensor with Arduino; as sound sensor detect clap or loud voice. When sound come, Arduino turn ON LED and buzzer and also this project for Simple Sound Sensor Circuit with Arduino help beginner understand sensor working. Arduino Code: Code Explanation: Circuit Working: Parts List: Components Quantity Resistors 220Ω […]
Arduino and Joystick LED Controller Circuit
This project shows how to control many LEDs using one joystick and Arduino; also the joystick moves in X and Y direction, then Arduino reads this movement and turns ON or OFF the LEDs. Moreover, this Arduino and Joystick LED Controller Circuit is simple to build and is good for beginners and Arduino lovers. Arduino […]
Measuring Bend Angle using a Flex Sensor Circuit
Flex sensor is a small strip that changes resistance when we bend it. When the sensor remains straight, it has low resistance and when it bends, its resistance increases; also many robots, gloves, gaming devices, medical tools, wearables, and other projects use this sensor. Additionally, sensor works simple, as with more bend it gives more […]
Arduino Flex Sensor Circuit
If we want Arduino to feel the movement, flex sensor is best; with no click, no sound only smooth bending, also it bends and Arduino gets new value every time. Perfect for beginners who want to control things by bending and further its a simple circuit, with simple code, powerful idea. Arduino Code: Code Explanation: […]
KY040 Encoder Module Circuit with Arduino
A rotary encoder is a sensor that detects rotation and direction; also people use it in volume knobs, motors, robot wheels and menu selection systems. Arduino can read the encoder pulses and show value in serial monitor; further this project for KY040 Encoder Module Circuit with Arduino is very simple and beginner friendly. Arduino Code: […]
