Hello Friends !
We are bringing to you one of the best IoT Project (Internet of Things) ideas which you can easily build for yourself. It also features in our list of Top 5 IoT Project Ideas for electronics students. This project uses ESP01 WiFi Module and can be used to remotely open a door using an App from anywhere in the world.
ESP-01 – ESP8266 is an UART-WiFi transparent transmission module with ultralow power consumption, specially designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
Step 1: What We Need
Step 2: Connections
For ESP-01 Breakout and Programmer
1) VCC => 5V
2) GND => GND
3) Rx => Tx
4) Tx => Rx
For ESP-01 Breakout and Servo Door Lock
1) 5V => Red Wire
2) GND => Brown Wire
3) D2 => Orange Wire
Step 3: Download the Blynk App
Blynk can be downloaded from the Play Store for android & the App Store for iOS. It is Completely Free!!
After downloading just Create a new account or Login via Facebook.
Now, Create a new Project – Add 2 Buttons from the Side Menu.
Button 1 : Tap on the Button => Select Pin as Virtual V1
Button 2 : Tap on the Button => Select Pin as Virtual V2
Step 4: Uploading the Code
Download the code from here. Open the code in Arduino IDE and change the Auth. Key, WiFi Name & Password.
Now, Select the board as “Generic ESP8266”. If you cannot find in your Boards, then you can follow this.
Now, Select the COM Port & Press the Upload Button.
NOTE:- Make sure to Set the ESP to Boot Mode while uploading a program. This can be done by pressing the “BOOT” button to “ON” & then pressing the “RESET” button.
