ADXL345 Interface to Arduino Using the ADXL345 with the Arduino is quite easy if you use the I2C interface, as this allows to controller to operate at 5V and the ADXL345 to operate at 3V3. Note: In I2C mode the SDO pin is an input, selecting an address....
Here’s the Arduino Code for this example. It’s quite simple. We just need to define the PIR Sensor pin as input and the relay pin as output. Using the digitalRead() function we will read the output of the sensor and if its high or if an object is detected it will activate the r...
We're using the Arduino based motion sensor data to notify the staff discreetly that someone has arrived with the use of push notifications and a flashing light. In addition to this we are using the data to predict when people will arrive so staff can get to the reception before a ...
As much as IMUs are picked for many applications, it’s still not an error-free option for motion sensing needs. Accumulated error, also known as “drift”, is one of the main disadvantages of IMUs. It is present due to its constant measuring of changes and rounding off its calculated...
In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
In our project, the Arduino Uno is programmed to make the robot move forward, turn right or turn left and stop according to the input coming from the sensor. The output of the Arduino is fed to the motor driver. Why We Require a Motor Driver? The reason to use a motor driver here...

Arduino Multitasking! How to Use Milli in Arduino Code October 11, 2017 by Ryan Jones Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train! Delay...
Why use Arduino? Simplicity Besides the main microcontroller chip, a microcontroller will require many different parts to work. What Arduino did was take away all the essential components of a microcontroller and design it so that it is effortless to operate on a piece of Printed Circuit Board ...
In this tutorial I will show you how I built an Arduino based hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has...
