In this tutorial, we are dealing with yet another interfacing technique. This time we are interfacing an RFID Reader which can read RFID Tags to Arduino. RFID is Radio Frequency Identification. An RFID reader is used to read RFID tags (which contain certain unique data stored in a chip). A...
How do Arduino based RFID Door Lock Work? This Arduino RFID Door lock system consists of an Arduino Development Board (Arduino UNO, Arduino Nano or other), an RFID reader module and an actuator like servo motor or solenoid lock to lock and unclock the door. All we need to do is swipe ...

Next we need to give life to the two buttons. So when the “TurnOn_Button” will be clicked we will use the Bluetooth client function “Send1ByteNumber” to send a number to the Arduino Bluetooth module. In our case that’s the number 49 which corresponds to the char...
The physical hardware of Arduino is the board itself. However, when it comes to Arduino boards, there are multiple varieties with different functionalities. Today we will be looking at ourSeeeduino V4.2, which has the same functions as one of the most popular Arduino boards – the Arduino UNO...
One of the most useful applications of a keypad is to use it for keyed entry. You can set up a password and have the Arduino activate a relay or some other module if the password is correct. The following code will activate a 5V relay when the password is entered correctly: ...
Are you trying to use the UART bridge that connects the USB interface to a (virtual) Com-port on your PC? Then you need to use the SCB - based component and connect Tx and Rx to Port4_0 and _1 When using a direct connection from your Tx and Rx pins P0_5 and _4 you will nee...
The Type of SD Card Module I have not tested this library with all the SD card modules, but I think it should work for majority of them, unless you are told by the seller that you should use a different library. The Library uses standard SPI interface for communication, which hasSPI bu...
IoT app features.To save your budget, decide on the core features of your IoT app and postpone the development of the additional ones to the later versions of your solution. UX/UI complexity.A simple and intuitive interface of your IoT app is something you should invest in at some point ...
RFID:I chose the RFID-12 from Sparkfun, as it's a tiny self contained module with a built in antenna, and it's dead simple to use. Just power it up, hold up a tag, and out pops the ID over 9600 Baud serial. This is used as a security feature for this version, but I plan ...
