The presence of 12-Multi-National Digital clocks is very common at the lobby / front desk of star hotels, showing time & dates of several countries where from most of the guests to arrive to stay at the hotel. One common feature of these clocks is that they are majestically looking elegant dial clocks! I tried to achieve that feature using a cheap ATMega-328 alias bare-minimum Arduino UNO microcontrolle ...

Monitoring the temperature of a transformer or electric motor winding involves data acquisition. This project is developed to monitor the temperature of an electric motor and a transformer with high accuracy, incorporating display and alarm facility. This circuit can be installed near a transformer winding or a motor’s location, or it can be attached to either of these using suitable support. It can track t ...

Global positioning system (GPS) synchronised clocks give accurate time. These clocks are universal and commonly used at railway stations, bus stands and airports. These are widely used for military purposes too. Here we describe a GPS clock based on Arduino Uno R3—an AVR ATmega328-based microcontroller board with six analogue inputs pins and 14 digital input/output (I/O) pins. The microcontroller has 32kB I ...

This Arduino based visitor alarm is useful for offices, clinics and shops. It alerts you to the entry of a visitor by producing a beep sound every time the door is opened. The alarm automatically switches off after a few seconds. Circuit and working Circuit diagram of the Arduino based visitor alarm is shown below. It is built around an Arduino Uno board (Board1), a reed switch (S1) and a piezo buzzer (PZ1) ...

Shadow alarms are usually used for protection against theft. A shadow alarm is a device that sounds an alarm when a shadow falls on it. Described here is a simple circuit of an Arduino-based shadow alarm. This compact shadow alarm unit is capable of sensing a moving shadow in a restricted area, and can be easily installed on a wall, window or door to protect your valuables from theft. Constant lighting is r ...

The objective of our project was to create an alarm system that could detect an intruder using an IR motion sensor. We used a keypad so the user could enter their password to arm and disarm the system. [gallery columns="2" size="medium" ids="31154,31155"] We also included an LCD so that users would be informed which state the alarm system was currently in as well as giving the user a response when entering ...

Smart Phone Controlled Arduino Mood Light with Alarm I recently purchased the Neo Pixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build somet ...

In this article, we are going to build an Arduino Real Time Clock using DS1307 RTC Module and 16×2 LCD module for display. First of all, let’s see how to interface RTC Module to Arduino. There are different kinds of RTC modules available in the market. We are using the most common RTC module comes named DS1307 IC, an LCD module and Arduino Uno for this tutorial. Interfacing an RTC module to Arduino is prett ...

Today we are building an Arduino based Automatic Pet Feeder which can automatically serve food to your pet timely. It has a DS3231 RTC (Real Time Clock) Module, which used to set time and date on which your pet should be given food. So, by setting up the time according to your pet’s eating schedule, the device drop or fill the food bowl automatically. In this circuit, we are using a 16*2 LCD to display the ...
