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.

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

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.

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.

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).

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

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 :)
