Story

Introducing NRF Attention Reminder– an electronic device designed to send alerts. A simple, single-button RF Transmitter sends a signal to a central RF Receiver, which displays the information and generates an alarm. Multiple transmitters can communicate with the same receiver.

NRF Attention Reminders can be used for a plethora of motives!

NRF Attention Reminder consists of two separate rectangular PCBs both having Arduino Nano. One board is a transmitter that consists of a push-button and NRF module. The receiver board consists of an NRF module, a push button, an LCD, a buzzer, and 5 LEDs.

How Does it Work?

NRF Attention Reminder works on a multi-transmitter and single receiver network. The NRF on the receiver module is in listening mode and accepts data from the transmitters. The data from transmitters that are already paired is accepted and all other data is rejected.

You press a push button on the transmitter, which causes the transmitter to send a specific message to the receiver. The receiver then shows a message on the LCD, along with that, the receiver switches on the corresponding LED indicating the transmitter number which has sent the message. Also, an alarm is generated using a buzzer to bring focus to the receiver.

Components and How They Work

  • Arduinos are codable circuits that help you easily create the base circuit for a transceiver module.
  • NRF Modules or NRF24L01 Modules are Radio Frequency based transceiver modules that can act as both a transmitter or receiver.
  • The push-button is used to generate input from the user. On the transmitter, it is used to initiate the transmission of a message. On the receiver, it is used to clear the display and reset the LEDs.
  • USB Plug connects the transmitter and receiver circuits to the power bank or computer to power them and to help upload the code from the computer into the Arduino.

The Real-World Application

NRF Attention Reminders can be used in places such as hospitals, home security, long-term care facilities, restaurants, and more.

Risks and challenges

These modules are still under the prototype stage. This Kickstarter campaign is done to share these kids’ innovations with everyone. These modules are suitable for testing and learning about RF communication systems. The NRF module is FCC certified and is safe to use. However, the whole Receiver and Transmitter boards have not been FCC certified. Hence, we highly recommend it for personal use and learning purposes only.
