Make connections as shown. Make sure you connect Ground Pin of RFID reader to Ground Pin of Arduino. I am using the SoftwareSerial Library of Arduino which enables digital pins to be used in serial communication. I have used pin 9 as the Rx of Arduino. (You can also use the hardware R...
Now let’s look at a simple example of using this shield with an Arduino. This example uses NB-IoT to communicate with a PC. User have to send an AT command through the PC to the NB-IoT module, and detect the strength of the signal. Step 1 Connect the NB-IoT Shield wit...
But before do that, we can connect our smartphone to this project so that we can see how the app is taking shape directly on our smartphone in real time. In order to do that first we have to download the MIT AI2 Companion app from the Play Store and install it on...
Of course, in a practical application, you will be connecting your serial connection to an actual device such as a modem, a printer or even some RFID readers, in fact, we use a serial connection in our tutorial on setting up the RFID RC522 Chip. For this Raspberry Pi serial tutorial, ...
