The Arduino-controlled relay circuit is shown below. This circuit explains to you how to control a relay with the help of an Arduino. The required components to build this circuit mainly include the Arduino Board, Resistors – 1K & 10K,BC547 transistor, 6V/12V relay, 1N4007 diode & a 12V...
Arduino Code - Multiple RFID/NFC Tags We can allow multiple RFID/NFC tags to activate the relay. The below code uses two tags as an example. /* * Created by ArduinoGetStarted.com * * This example code is in the public domain * * Tutorial page: https://arduinogetstarted.com/...

You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.A simple way to test this is to use an ‘if’ statement to check the value stored in ‘btstate...
Language: The primary programming language used in the Arduino IDE is C/C++, though it is often referred to simply as Arduino code or sketches. Sketches: These are Arduino programs that are written in the IDE. They use the Arduino libraries and can be used to control the board's behavior...
I have 4 of the ZS-040 adapters. I am trying to learn the code but every time I try to connect to the bluetooth it just says connection rejected. When I put in the AT commands I get nothing back. Any Ideas? I’m looking to do some master to multiple slaves to multipule slaves....
Arduino IF Statement Code Examples by Lewis Loflin Video for this page: Arduino Comparison IF Operators Think of a micro-controller as a box full of basic logic circuits, gates, etc. To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulat...
One of the other characteristics in the code for the LCS is that it uses multiple tabs in the Arduino IDE. Most of these tabs consist of a single function that we discussed in the above paragraph. Multiple tabs can help you organize your programs. It also breaks down long, complicated pro...
The project inclues two clients, an Android application and a C client for control from Linux systems.The Android app supports multiple relay servers, relay groups, homescreen widgets, and NFC (near field communication) tags.A demo video and brief description of how it works is available at: ...
