Flex sensor is a small strip that changes resistance when we bend it. When straight, resistance is low. When bent, resistance becomes high. Many projects use this sensor. It is used in robots, gloves, gaming, medical tools and wearables. Sensor works simple with more bend gives more resistance. Flex Sensor Output Voltage Comparison Graph: Circuit […]
Arduino Flex Sensor Circuit
If we want Arduino to feel the movement, flex sensor is best. No click, no sound only smooth bending. It bends and Arduino gets new value every time. Perfect for beginners who want to control things by bending. Simple circuit, simple code, powerful idea. Arduino Coding: Code Explanation: Circuit Working: Parts List: Item Quantity Resistors […]
Simple Push Button Circuit with Arduino
This project show how to make very Simple Push Button Circuit with Arduino. Push button act like an ON and OFF switch. When we press button one time then LED changes its state. First press LED will turn ON. And second press LED will turn OFF. It keeps doing the same. All this happen with […]
KY040 Encoder Module Circuit with Arduino
Rotary encoder is a sensor that tell rotation and direction. It is used in volume knobs, motors, robot wheels and menu selections. Arduino can read the encoder pulses and show value in serial monitor. This project for KY040 Encoder Module Circuit with Arduino is very simple and beginner friendly. Arduino Coding: Coding Explanation: Circuit Working: […]
Solenoid Door Lock Circuit with Arduino
In this project we have used Solenoid Door Lock Circuit with Arduino Solenoid lock works like magnet latch. Arduino control it using small signal. With few parts and simple wiring, we can create automatic locking system for our home or office. Very easy and very useful circuit and is good for DIY security system. Arduino […]
RF Transmitter Receiver Circuit with Arduino Uno
This project uses RF 433MHz module. One Arduino work like transmitter and other like receiver. When we press button on transmitter side, LED on receiver side go ON or OFF. This RF Transmitter Receiver Circuit with Arduino Uno is very simple. Good project for new beginners. Range is small but enough for small hobby work. […]
