Open-Smart Tft Lcd Shield Hx8352B Projects Source Code Code As Touchswitch

These switches have mechanical moving parts that get damaged on continuous use.

These modern touch switches have extra functions and, as no moving parts are involved, these last longer than the traditional ones.

Despite these advantages, touch switches are quite expensive.

The panel can be used to control electrical appliances either through Arduino based touch switchboard or wirelessly through an Android app.

Arduino based touch switchboard can also display room temperature on the smart touch panel screen (refer Fig.

TFT touch display shield (6cm) used in this project is shown in Fig.

For this, go to the Sketch menu and click on Manage libraries option (Fig.

Then search the library name and click on the install button.

The libraries needed for this project are Adafruit GFX, TouchScreen, and NTC thermistor.

Install them, as shown in Fig.

Fig. 5, and Fig. 6.

Every touchscreen has its own library.

Save the code as touchswitch.ino.

Compile it and upload the code into the Arduino Uno board.

You will find two tabsDesigner and Blocks on the top right side of the screen.

Pick and place the code blocks, as shown in Fig.

Save the project as TouchSwitch.apk and install this.apk file on your Android phone.

The circuit diagram is shown in Fig.

The connection details between Arduino and other components are shown in Table 2.

Then enclose all the components, including the Arduino board, TFT touch display shield, and relay module in a suitable plastic box, as shown in Fig.

Place TFT touch display carefully in the enclosure, as shown in Fig.

The final touch control panel on Android for wireless control is shown in Fig.

When you are sure that all the connections are correct, power on Arduino and relay module with 5V DC, and then plug AC appliances connected to the relay for switching.

When you touch the on button, it will switch on the electrical appliance connected to it.

First two control buttons (on and off) in the first row of the touch panel shown in Fig.
