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 ...
If you are completely new to IR sensors and wish to learn more you can check our Arduino IR sensor tutorial, where we have explained the basic working of the IR sensor module and how to use it with Arduino. You can see our main controller, the “Arduino UNO R3”, is responsible for...
To use the IR sensor with an Arduino, connect VCC with 3.3V or 5V pin on the Arduino. The OUT pin can be connected to digital pins of the Nano board. The GND pin will be connected to Arduino Nano ground. Once the connections are made, you can use the Arduino’s programming environme...
The LED is used to signal that the sketch is recording a gesture If you want to use your own trained data, replace #include "digits_model.h" with your own, then replace const char* GESTURES[] with your own trained gestures Arduino IDE vs: 1.8.12 ...

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...
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...
Philips Hue range of lights are certainly not cheap (there are some alternatives), but one thing that I really appreciate is the well documentedAPIfor making your own Hue apps. Today I'll be showing you how to control your Hue lights from an Arduino - then adding a simple motion sensor....
