NRF24L01 interfacing with 8051 – Wireless Xbee

In our previous tutorial, we have seen a gas detection sensor interfacing with 8051. NRF24L01 interfacing with 8051 tutorial is intended to enable wireless data transfer for 8051.  So to do that, we will interface nRF24L10 with 8051. This will enable us to transfer the data wirelessly (by air) between two 8051 boards using NRF24L01. … Read more
