In this project we will see how to create an Arduino-based smart lock that can be unlocked from your mobile phone; we will therefore see how to generate a specific QR code, how to create an access page from ESP8266 and finally you will be able to open the door using your phone. We…
Imagine having all your devices connected via one smart voice assistant giving you the ability to turn things on or off as you wish. Well, you can do exactly that. Read on to see how you can control any electrical appliance with the help of Google Assistant. More info
Let’s interface our Energy Meter with Internet to bring measurements to the ThingSpeak platform and see the results in convenient graphs. A few posts ago, we introduced the MCP39F511 integrated circuit, capable of performing electrical measurements in single-phase electrical systems through the FT1346M board. We have integrated it with the GSM board and…
This project is about making Smart System using BoltIOT kit which will send the notification via SMS automatically (send by system) to house owner when the intensity of Sunlight increase or decreases, So they will easily turn ON/OFF the out side lights of the house with the help of Smartphone. if any delay in turning…
The project was born with the purpose of helping the deaf community to communicate and interact easily with the surrounding environment. The goal is to convert the basic symbols representing the 26 letters of English alphabet and display them on a smartphone screen. For this system we were inspired by the idea of controlling a…
In this project we see how to make a Bluetooth speaker with a clock. It displays date, time, temperature and humidity and it is updated from Internet at 15 minute intervals. It also has a 32-band audio spectrum analyzer that displays different musical patterns. The clock or spectrum analyzer can be displayed while playing music….
Hardware required The Bolt Wifi module 3 female to male wire Temperature Sensor: LM35 sensor Connections Connecting the LM35 sensor to the Bolt Step 1: Hold the sensor in a manner such that you can read LM35 written on it. Step 2: In this position, identify the pins of the sensor as VCC, Output…
In this project we see how to create an I2C system to control motors using a DigiSpark Attiny85 plus an Arduino shield. To test its operation we made a small RC car that uses an M5StickC and connects to the Blynk app to communicate via the I2C protocol. We used two communications in this project…
With 10 million Arduino UNO sold worldwide, this board becomes the most widespread prototyping board ever. The first Arduino UNO board was introduced in 2005 and in those days integrating a communication system such as WiFi was extremely expensive. So why not think of something that would allow all owners of this board to make an…
This project focuses on developing home security solution using lasers and live alert service. The security setup can only be passed (without triggering alert) using the Bolt IOT Android app and then entering the correct password. The project works using the combination of Bolt IOT module and Arduino along with Twilio providing the messaging service….
We emulate the TDG series remote controls using the GSM Shield. It’s not been long since we presented our GSM shield for GSM/GPRS modules SIMCom, QUECTEL, FIBOCOM etc. that was born to be incorporated in Arduino-based projects involving cellular connectivity; now it’s time to move on to the first practical application, which in this case…
In this project we will see how to build a pair of glasses in which the circuits for Bluetooth headsets are inserted in the frame. Therefore you can listen to music wirelessly while wearing. The circuit consists of three main parts: audio amplifier circuit, bluetooth module and charging module. The TP4056 acts as a charging…
