The project “Arduino and GSM Based Automatic Answering Machine” is designed to answer the phone call with prerecorded message when we are unable to attain call. Sometime in this busy world we might not be able to attain the phone call due to several reasons (generally when we are in bathroom or watching movie in cinema or forget mobile in home). These calls might be important i.e. call might be from office or business call which cannot be ignored. Thus, the project posted here receive the call after three rings…

Today in this article we are going to build a project called Accident Detection and Alert System using Arduino UNO, GSM module, GPS module, and Vibration Sensor Module. The vibration sensor module used in this project is used to detect the change in linear velocity, displacement, or acceleration. The GPS module detects the exact location (longitude and latitude) and the GSM module is used to send all information to the mobile number assigned in the software code. You may also like the Car Lock System using Arduino and GSM modules.…

Few day ago, I got an email from one of reader of bestengineeringprojects.com asking about how does the traffic police know the concentration of alcohol present in our breadth. For that purpose, I had designed a project called DIY Breathalyzer using various easily available electronics components. Before starting about description of project I would like to describe what breathalyzer is. The breathalyzer or breathalyzer is an electronic device which is used to estimate the concentration of alcohol available in breath sample. This device is usually carried by traffic police, medical…

The project ‘Dark Sensor using Arduino’ uses an arduino board, a LDR and switching circuit. The circuit is basically a light operated circuit which operates when dark is detected on LDR. Circuit Diagram of Dark Sensor using Arduino. Circuit diagram of the projects ‘Dark Sensor using Arduino’ is shown in figure 1, build around a arduino uno board, a LDR, three transistors and few other electronics components. The LDR is basically a transducer which change one form of energy to another form (change in light intensity to change in resistance).…

Basically, RGB represent three basic colour RED GREEN and BLUE which is used in our digital system for generation various other colour. The project ‘RGB Colour Generator using Arduino’ is basically a tutorial on how to generate colour code and hex code of that color. Circuit Description of RGB Colour Generator using Arduino The circuit of RGB colour generating using arduino is basically designed using a microcontroller unit (Arduino uno), a 16×2 alpha numeric LCD, a RGB LED and few resistor and variable resistor. The circuit diagram is shown in…
