Description:

In this project we are building a Restauran Menu Ordering System using Arduino. This menu system can be used for ordering food in restaurants along with calling for server/waiter and bill. In this a TFT Display Shield for Arduino UNO is used, it is touch display and has the menu displayed on it. A person can choose the food item and send the order to the kitchen or whatever it is. A buzzer is attached to the kitchen side and goes brrrrrr when any order or command is received. RF Transmitter and Receiver is used for communication. Arduino UNO and Arduino Nano is used.

Components:

SR. NO.	COMPONENT	PINOUT DIAGRAM	BUY
1	Arduino UNO	Arduino UNO Pinout Diagram⇗
2	Arduino Nano (Here, other Arduinos can be used too)
3	TFT Display Shield for Arduino UNO
4	433Mhz FS1000A RF Transmitter
5	433Mhz XY-Mk-5V RF Receiver
6	Buzzer
7	16×2 LCD Display
8	I2C Module for 16×2 LCD Display

Steps and Info:

1. Get correct components as given. You can buy online or offline. I buy electronics components mostly from Amazon.

2. Start connecting the components. If you are new to connecting components in an electronic circuit, then use a Breadboard or you can straight up make connections using Jumper wires but it will create problem when there will be two or more connections needed at one pin (for example two or more different sensors 5V connection to Arduino’s 5V pin). But before soldering components on a PCB or printing a PCB for your circuit, better try using breadboard so that any errors and mistakes can be observed on breadboard and not after soldering. Or do connections in your way.

3. Now after building the circuit, download the Arduino IDE from https://www.arduino.cc/ website.

4. If you are new to Arduino IDE software, then watch this video we made specially for beginners about Arduino IDE.

5. If you know Arduino IDE then straight up copy the code we given and paste it into the Arduino IDE sketch. You will need to manually install few libraries in the Arduino IDE software. Links to the libraries given below in Links section.

6. Connect the Arduino to your Computer/device. Select a proper port, proper Arduino type and whatever other settings are. Here it is Arduino UNO. (If you don’t know what this all is then watch our video: ).

7. Compile the code and Upload it.

8. If any error occurs then try to troubleshoot it by finding/copy-pasting it into our Solve Errors page https://electronicsprojects.in/solve-errors/, or you can straight up paste the error on Internet and you know the rest. Also check if there are no spelling/syntax errors in the code. Compile the code again once to check if errors are fixed. I have given proper connections and code but still nothing is perfect.

9. Once code compiles and uploads smoothly, you can start testing the working of your circuit/project.

10. Once both transmitter and receiver circuits are ready, turn them ON using the USB to your device/powerbank or connect 12v Battery or 12v 1amp charger.

11. On transmitter circuit, a menu will show up on the TFT Display, start choosing the food, calling waiter or bill and check if the buzzer makes sound on the receiver circuit.

12. If it doesn’t then check connections and code. Also you can talk with me and the community through discord. All the links to social is given at the right side of this page.
