Arduino Projects & Tutorials

Simple Raspberry Pi Projects. This section of EG Labs brings you some interesting projects based on Raspberry Pi. Explained with the help of circuit diagrams, source codes, and working videos, these Raspberry Pi projects can serve as a good reference for final year electronics engineering projects.

I made this project in order to build a surveillance car which can be controlled over Internet or any private network. My objective was to easily and cost effectively do something that can be used for security purposes. My car uses DTMF module which takes it’s input from mobile phone attached to the car, that mobile is not only used to generate DTMF tones but also for the surveillance by providing Live Footage from it’s cameraover the network using AirDroidConventionally, any project using DTMF requires call from another cell phone to the one attached to the project, which is not cost effective, but in case of my project I used an android app DTMF Tone Generator which generates DTMF tone, now for this to work I shared my phone’s screen over the network using VNC serverhence cost effective.To make this Idea more effective I mounted the phone on a servo motor. This gave my Camera one degree of freedom, i.e. I can move it left and right without moving the bot.

This is a project based on Arduino board which can measure the unknown DC current values. When wefed the current to a load device through the breadboard circuit, the 16*2 LCD displays that current value. The project uses an Arduino pro mini boardwhose ADC feature is used along with the concept of Ohm’s law to develop this ammeter.

 

 

This is a project based on Arduino board which can measure the unknown AC and DC voltages. When we connect the unknown voltage on the breadboard circuit, the 16x2 LCD displays the voltage value. The project uses an Arduino pro mini board whose ADC feature is used along with the concept of Voltage Divider circuit to develop this Voltmeter.
