LED Display Board using Arduino

In this DIY session we are going to use a 32×16 LED dot Matrix display module which is also known as P10 LED Display Module to display a scrolling text by using Arduino UNO. P10 modules can be cascaded to build any size of the advertising board.

Automatic Bottle Filling System using Arduino

Here we are going to design a prototype for Automatic Bottle Filling Machine using Arduino Uno, conveyor belt, solenoid valve, IR sensor, and Stepper motor. Belt conveyor is driven by a stepper motor at a constant preset speed. The stepper motor will keep driving the belt until an IR sensor detects the presence of a bottle on the belt. We used the IR sensor as an external trigger. So whenever the IR sensor goes high it sends a trigger to Arduino to stop the motor and turn on the solenoid valve.

Arduino Controlled Musical Fountain using Sound Sensor

The basic idea of this Arduino Water Fountain is to take an input from any external sound source like mobile, iPod, PC etc., sample the sound and break it down to different voltage ranges, then use the output to turn on various Relay. We first used a condenser mic based sound sensor module to perform on the sound source to split the sounds into different voltage ranges. Then the voltage will be fed to op-amp to compare sound level with a particular limit. The higher voltage range will correspond to a relay switch ON which comprises a musical water fountain operating to the beats and rhythms of the song. So here we are building this Musical Fountain using Arduino and sound sensor.

XBee Module Interfacing with Arduino

In previous tutorials we have learned about ZigBee protocol and its architecture, and also learned about wireless communication between two Xbee modules. Now in this tutorial we will interface XBee module with Arduino Uno board. The XBee connected with Arduino board will act as a receiver and it will communicate wirelessly with other XBee module which is serially connected with the laptop using a Explorer Board. So lets explore further for Arduino wireless communication using XBee.
