An Inertial Measurement Unit (IMU) is defined as a 9 axis sensor that measures orientation, velocity, and gravitational forces by combining Accelerometer, Gyroscope, and Magnetometer into one. IMUs typically come in large packages, but with recent developments like MEMS technology, they are now ...
The pin header is attached to the Arduino kit’s board and provides an easy connection to a microcontroller’s tiny, fragile pins via easy-to-find pin plugs.Pin Plugs: A pin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to ...
There are many people have been writing Arduino codes for this IMU, and there are even libraries available for these sensors. You can find the accelerometer ADXL345 libraryhere. This is an example code how to use the ADXL345 library. It takes sensor measurements, calculate a human friendly va...
Arduino Interface Circuit Just like most resistive sensors (like a thermistor), the best way to connect this sensor is through a voltage divider as shown: With the setup above, the A0 pin receives an increasing voltage as the bend on the sensor is increasing. Here is an example Arduino sket...

How to Use a Magnetic Door Switch / Sensor With Arduino: In this tutorial we will use one magnetic - contact door sw / sensor and a buzzer for making a "noise" when a door is opened. Normally the reed is 'open' (no connection between the two wires). The
Arduino Uno MQ-3 Alcohol Sensor – Connection Diagram Now that we knowhow the MQ-3 alcohol sensor works, we can connect all necessary wires to an Arduino Uno and see how it functions. We'll start with the analog component and then go on to the digital part, which is pretty simple. ...
BMP280 Pressure Sensor Module Interfacing with Arduino If you want to build your own temperature monitoring system or to measure the altitude of your drone or simply want to measure the atmospheric pressure in your area, then one of the best module for you to use in your project is the BM...
How to filter noise from sensor reading in Arduino code?AnswerThe reading value from sensors may includes noise, especially for analog sensor or environment-sensitive sensor such as ultrasonic sensor. You can use the below method to remove the noised values....
Resistors can also be used to pull up or pull down a GPIO pin. A pull up resistor will pull a pin high by connecting a voltage supply to a pin. A pull down resistor will pull a pin down to GND.We used a 10K Ohm resistor with a DHT22 temperature sensorto pull the data pin high...
