This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900 . It’s the cheaper module now available in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented here . You can buy the GSM module premounted here . This …
We purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago. It’s a very nice product for adding visual elements to your projects at a very low price. We paid £3.89 for the screen and it was delivered a few days later. Take a look …

Dorm rooms are notorious for their dreadful lighting, so I wanted to make a cool alternative light source for my room at school. I made it phone controlled so there would be an easy and wireless way to change the color of the lighting. The lighting consists of Tricolor LED Strips and are controlled by …
When using an Arduino, it may result quite annoying to not be able to use it just because you do not have a computer available. Maybe the Windows or Mac OS isn’t compatible, you don’t have any computer at all or you just want more freedom for interfacing your board. The solution: a simple OTG …
This project slightly modifies the Google Android sample app called “Bluetooth Chat” so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality: Android talks to Arduino 1. Run the Android “Bluetooth Chat” sample app (after we modify the app in this instructable). …
Ever wanted to have a Phone Book, controlled using a microcontroller, which is very easy to use, and you can use it while talking on phone, and is saving data on SD Card? then this instructable is for you. In this instructable you will learn how to make an arduino controlled Phone Book, and you …
Connect the Arduino outputs with 5 volt power to the relay coils. Use a separate 9 or 12 volt battery for powering the motor. Connect the 9 or 12 volt power to the relay contacts and the motor. Be sure to avoid connecting the 9 or 12 volt power to any of the Arduino input …
A quick circuit showing how to control the speed of a DC motor with a potentiometer with your Arduino board. Also shows how to use a TIP120 transistor to allow the Arduino control a larger power supply. Transistors are 3 pin devices, which via the 3rd pin (Base) allow it to control the current passing through the other 2 pins (Collector and Emitter). …

n this Instructable we will simulate an Toll Booth Gate by using a manual Push Button to open and close the gate. How Does It Work? When the vehicle comes in front of the gate, the push button is pressed & the gate is opened, this is done by sending a command via microcontroller to the servo to open the gate …
