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 ...
Arduino is mainly used to build electronic projects for everyone – electricians, tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, ...
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...
Connect the NB-IoT Shield with the Arduino UNO. Step 2 Insert a Micro-SIM Card to the Micro-SIM interface on the NB-IoT Shield. Step 3 Connect the Arduino UNO to the PC Step 4 Open the Arduino software, and click “File–>New”, and save the new file ...

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...
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: ...
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 ...
types of interface on the GPIO header. Raspberry pi I2C interfaces aren’t enabled by default and need some extra configuration before you can use them. After connecting the wires accordingly to the devices, you can can start the communication with the devices with the help of related libraries...
