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 or place an authorized RFID card in front ...
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...
This makes the Arduino Extremely Easy to use. Arduino TheArduino projectmakes it even easier to use microcontrollers as it gives you an open source compiler and simple IDE (Integrated Design Environment). It lets you program in C/C++ and upload programs very easily with the push of a button....
Furthermore, Arduino’s easy-to-use IDE software for beginners is a more manageable program to learn as it uses a simplified version of C++ compared to other programming software. Because of this, Arduino is commonly cited as the pathway for everyone looking to learn about microcontrollers. With...
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...
After opening a subkey (don't forget true! as it give you permission to delete), we can use the autoshell in order to change any value in the following subkey.5- Hints to use registry with VB.netWe can count the values in a hiveMy.Computer.Registry.CurrentUser.ValueCount.ToStrin...
Example: Manually send AT Commands to control the NB-IoT Shield 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 th...
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: ...
Installing a library to help us control servo motors connected to an ESP32 development boardSince I was not able use the default Arduino Servo library, I had to find another library to control the servo motor.Given that, I proceeded to install the ESP32Servo library by John K. Bennett and...
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...
