Wirelessly Connect LCD with Mobile: A Step-by-Step Guide
What To Know
- We have seen in the previous article that we can use the LCD in a normal way with the help of a microcontroller.
- We can see in the above diagram that the Bluetooth module is connected to the LCD in a serial manner.
- A wireless LCD can be placed anywhere within range of the wireless signal, while a wired LCD must be connected to a specific port.
We’re living in a wireless world. Whether it’s your smartphone, your smart speaker, or your smart TV, it seems like everything is connected to the internet these days. And with the rise of the Internet of Things (IoT), that’s only going to become more true.
How To Connect Lcd With Mobile Wireless?
We have seen in the previous article that we can use the LCD in a normal way with the help of a microcontroller. Now, in this article, we will see how we can connect the LCD with a mobile phone wireless. We can display any data on the LCD with the help of a smartphone application. We can use any application to show data on the LCD. To do so, we need to interface the LCD with a Bluetooth module. The Bluetooth module will act as a medium to send data to the LCD.
Connection of LCD with Bluetooth Module
We know that the LCD has 16 pins. Out of the 16 pins, we have to power up the LCD with 3 pins. Those 3 pins are VSS, VDD, and GND. The other 13 pins are used for data transfer. We have to connect the data transmitting pin of the Bluetooth module to the data receiving pin of the LCD.Similarly, we have to connect the data receiving pin of the Bluetooth module to the data transmitting pin of the LCD. Let us now see the connection diagram between the LCD and the Bluetooth module.
Connection between LCD and Bluetooth Module
We can see in the above diagram that the Bluetooth module is connected to the LCD in a serial manner. We have used the serial data transmitting and receiving pins of the LCD to connect it with the Bluetooth module. We have not used the other pins of the LCD as we are not using them in this project. Now, let us have a look at the complete circuit diagram to understand the connection between the components.

The complete circuit diagram is shown in the figure below.
What Is The Difference Between A Wireless And A Wired LCD?
- A wireless LCD uses a wireless connection to display information, while a wired LCD uses a physical connection
- A wireless LCD is easier to install and set up, while a wired LCD requires more physical work
- A wireless LCD can be placed anywhere within range of the wireless signal, while a wired LCD must be connected to a specific port
- A wireless LCD is more portable and can be moved around, while a wired LCD is fixed in place
- A wireless LCD may have a shorter battery life than a wired LCD, depending on how it is used
How Do You Connect A Wireless LCD To A Mobile Device?
1. power on the wireless LCD and your mobile device.
2. On your mobile device, go to the settings menu and select the Wi-Fi option.
3. Under the Wi-Fi option, you will see a list of available networks. Look for the network name that matches the one on your wireless LCD.
4. Tap on the network name and enter the password, if prompted.
5. Once you are connected to the network, you will see a checkmark next to the network name.
6. Open the app on your mobile device that you want to use with your wireless LCD.
7. Look for the Wi-Fi option within the app and select it.
8. A list of available networks will appear. Select the network name that matches the one on your wireless LCD.
9. Once you are connected to the network, you will see a checkmark next to the network name within the app.
10. You are now ready to use the app with your wireless LCD.
It’s important to note that the specific steps may vary depending on your mobile device and the app you are using.
What Are The Benefits Of Using A Wireless LCD With A Mobile Device?
1. Increased mobility: A wireless LCD allows you to take your mobile device with you wherever you go. This is especially helpful if you need to use your mobile device for work or school, as you can take it with you and still have access to a larger display.
2. Increased productivity: A wireless LCD can help you be more productive by providing a larger display to work on. This can make it easier to see what you are doing and to read documents or emails.
3. Increased entertainment: A wireless LCD can also be great for entertainment, as it can allow you to watch movies, play games, or listen to music on a larger display.
What Are The Drawbacks Of Using A Wireless LCD With A Mobile Device?
There are several drawbacks to using a wireless LCD with a mobile device. First, the wireless LCD may not be as reliable as a wired LCD. The wireless connection may be interrupted by other wireless devices, or by physical obstacles such as walls or furniture. Second, the wireless LCD may not have as much battery life as a wired LCD. The wireless connection may consume more power than the wired connection, which may reduce the battery life of the mobile device. Third, the wireless LCD may not have as many features as a wired LCD. The wireless connection may not support all the features of the mobile device, such as touch input or voice recognition. Finally, the wireless LCD may be more expensive than a wired LCD. The wireless connection may require additional hardware, such as a wireless adapter or a battery, which may increase the cost of the LCD. Despite these drawbacks, using a wireless LCD with a mobile device can still be a convenient and effective way to access information and interact with the mobile device.
How Do You Troubleshoot Issues With A Wireless LCD?
If you’re having issues with your wireless LCD, there are a few things you can do to troubleshoot the problem. First, make sure that the LCD is properly charged and that the power switch is turned on. Next, try to reset the LCD by holding the power button for 10 seconds. If the problem persists, you may need to check the connection between the LCD and the computer. Make sure that the USB cable is properly connected and that there is no damage to the cable. If the problem still persists, you may need to contact the manufacturer for further assistance.
Here are some other tips for troubleshooting issues with your wireless LCD:
1. Make sure that the LCD is properly cleaned. If there is any dust or debris on the screen, it can cause the LCD to not work properly.
2. Try using a different USB port on your computer. Sometimes, the USB port on your computer may not be compatible with the LCD.
Wrap-Up
So, you want to connect your LCD to your mobile wireless? Well, that’s not a problem! All you need is a few easy steps and you’ll be on your way to enjoying your LCD from anywhere in the world.
First, you’ll need to find a suitable wireless module. There are many options available, but we recommend the ESP8266-01. This module is cheap and easy to use, and it’s compatible with a wide range of microcontrollers.
Next, you’ll need to connect the wireless module to your LCD. This is a simple matter of soldering a few wires to the appropriate pins on the module and the LCD.
