#220

In part one of this video, we started to answer the nine most important questions about wireless communications for Arduino Makers. In this video, we will continue and dig more into the matter. If you did not already watch the first part, I strongly suggest clicking on the link in the upper right edge of your display now.
Grüezi YouTubers. Here is the guy with the Swiss accent. With a new episode and fresh ideas around sensors and microcontrollers.
In the first part, we talked a lot about the influence of carrier frequency and started to understand the concept of bandwidth. In this video, we will cover
The significance of bandwidth on wireless communication
The different modulation principles
Methods to increase the reliability of wireless connections
And we will learn which methods were preferred by spies
And we will use all our knowledge to compare two well-known wireless modules, the NRF24L01, and the RFM69. Both representing very different concepts
