Wireless Communication On The Power Breadboard

Building the Wireless Communication on the Power Breadboard provided many benefits. One of them is the ability to tap into a stable power source. We will also improve the original code by adding some cool features on the receiver end so wait for the surprise! Finally, we will use jumper wires to make all the connections to all the components together to archive a clean and neat finish.

• 2 nRF 24 Breakout Boards
• Power Breadboard PBB-272 Series
• LEDs
• Jumper Wire

What is the nRF24 communication module?

One of the biggest benefits of the nRF24 is that the board can act as a dual-purpose device, where the nRF24 can turn an Arduino to be a transmitter and receiver. What this means is, that an Arduino can receive data and pass it on through a large network

This opens up the possibility of projects due to the flexibility of the board. Circuit Specialists want to change the norm of expensive communication hardware, that is what this project is all about, low cost and easy access. 

How to Solder Header Pins?

There are a couple of tricks you can use to ensure a clean soldering job. The header pins will help connect the Arduino to the power breadboard so you want to make sure not to burn it and cause a loose connection.

How to Solder Extention Pins to Header Pins?

The nRF24 breakout board would need to add some extension pins so to the exiting harder pins because we want the board to be able to plug into the power beadboard PBB-272C.

Wiring: ( same for transmitter and receiver)

• VCC – 3.3V
• GND – GND
• CE   –  pin 9 
• CSN –  pin10
• SDK  –  pin 13
• MOSI – pin 11
• MISO – pin 12

The Code

The nRF24 breakout board is optional, it would keep the power to the nRF24 radio module constant and provide a better connection. If you decide to go with the nRF24 breakout board, the wiring will be the same however now you can supply it with 5V.

The code would be simple and straightforward when you press the switch button, the receiver reads the signal and turns on the LED. 

The Transmitter code:

Conclusion

The Wireless Communication Network Developer (WCND) kit has been covered before here in our Maker Pit. However, building Wireless Communication on the Power Breadboard provided many benefits. Firstly, use the Power Breadboard PBB-272C to make the archive a clean look upon finish. Secondly, the ability to tap into the power source anywhere on the boards. Moreover, we also want to celebrate the Fourth of July by programming the National Anthem when the button is triggered.
