Introduction: Remote Number Counter

Hi guys, welcome!

This is my first share on instructables. I'm going to talk about how to make a remote counter with multiple buttons.

The transmission is based on 433MHz Wireless Transmitter and Receiver Module.

Let's get started.

Supplies

  1. Arduino Nano / Arduino Uno (Either works)
  2. WayinTop 3 Set 433 MHz RF Wireless Transmitter, Receiver and Antenna Kit
  3. 9V Battery
  4. Buttons
  5. 10k Resistor
  6. Wires, including jumpwires
  7. Breadboard

Step 1: Basic Instructions

If you are new to these, here are the basic instructions for buttons, wireless transmitters and receivers.

I found ⬆️this tutorial⬆️ quite helpful to me as a beginner with wireless transmission.

Step 2: Hardware Installation

The Arduino Nano and Uno board are meant to demonstrate that I am using different Arduino Boards to install them. The 2 parts are separate. If you only have 2 Arduino Uno boards or 2 Arduino Nano boards, that also works.

Step 3: Source Code

While you are uploading the code to the board, please remember to choose the board accord to your hardware.

The Button-Send one is for the remote number counter (the one with the Nano board in my demo) and the Button-Receive one is for the receiver (the one with the Uno board in my demo).

Step 4: Result

After you have done the uploading, press on the buttons. You can open the Serial Monitor to check the count of each button.

Step 5: Further Exlopration

Please feel free to leave a comment or ask me any questions!

You can also add as many buttons as you want to DIY your own remote counter :)
