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 Sleep Modes and How to use them to Save the Power
Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem almost every controller comes with a sleep mode, which help developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power saving mode by turning off the unused module.

Arduino HM-10 BLE Module Tutorial

The HM10 has become a very popular Bluetooth 4.0 BLE module. The HM10 is a Bluetooth 4.0 based module only, so it will not connect with Bluetooth 2/2.1 module such as HC-05, HC-06 and other Bluetooth modules. The HM10 is controlled via AT commands sent over the serial UART connection. HM-10 is a Bluetooth Low Energy (BLE) module, to know more about this module, check out the HM-10 BLE datasheet

Node.js with Arduino: Controlling Brightness of LED through Web Interface
We have seen numerous examples of Blinking an LED using different Microcontrollers and different programming languages. Today, we will use a very popular JavaScript framework  Node.js to control the LED connected to Arduino Uno. We will also use Node.js to control the brightness of LED from a webpage using Arduino. By few tweaks and using ESP8266, this can be converted into an IoT project where the LED can be controlled from anywhere.

Arduino 7 Segment Display Clock

This tutorial is about making a Digital clock by multiplexing four- 7 segment displays using Arduino UNO and displaying the time in HH:MM format.

ESP8266 Based Webserver to Control Servo Motor from Webpage

In this project, we are controlling a Servo Motor using a web browser with the help of Arduino and ESP8266. ESP8266 wi-fi modules is a cheap and powerful device, helps in communicating with any microcontroller, like here Arduino UNO.

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.

Arduino Based Guitar Tuner

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words, “My hearing was no longer tuned” and as a result of this, I was not able to tune the guitar without the aid of a keyboard or a mobile app which I later downloaded. The weeks went by till few days ago when the maker in me became motivated and I decided to build an Arduino based Guitar Tuner. In today’s tutorial, I will be sharing how to build your own DIY Arduino Guitar Tuner.
