In this post I will show you how you can communicate between two Arduino Boards using HC-05 Module. I am using Arduino IDE's version 1.8.7.  There are now newer modules that use a 3.0-20170601 firmware due to which module gives an error, But I will show you how you can fix this error. Just follow the exact same steps listed below and you will not get any error. Material Required-: PCB Board Arduino Uno x 2 Led Bluetooth Module(HC-05) x 2 Push Button (Switch) Resistor (1k ohm) Jumper Wire Connection for AT Mode -: 5V to Arduino 5V GND to Arduino GND TX to Arduino TX(D1) RX to Arduino RX(D0) Enable Pin to 5V Connections for AT Command Mode Step-1: Upload Blank code on Arduino Board. Step-2: While connecting supply to module long press the "Key Button" situated above enable pin. Now, You will see a delay in flashing of HC-05 led, that's means you are successfully entered in AT Command Mode. Step-3: Now open serial monitor . Remember that HC-05 requires Both "NL and ...

Here's a "Automatic Water pumping system" which controls the  water pump motor. The motor gets automatically switched on when water in tank falls below the lower limit . Similarly, its get switched off when the water is filled up( upper level ). This circuit is built with the help of 555 Timer IC Which is best and cheap.    Material required-: PCB Board 555 Timer IC 1k ohm Resistor x 2 220 ohm Resistor x 2 2 Pin Screw Terminal 5V Relay Battery(9v) Transistor (BC 547) Diode (IN4007) Led  Automatic Water pump Circuit-: If you guys have seen my previous post of relay module you must somewhat familiar with upper part of the circuit ,in which we just have to trigger the base pin of transistor to turn the relay on .Just like that, Here we are using output pin (3) of 555 IC to trig the base pin .   When the water level goes up and touch the pin 6 of 555 IC ,output of Pin 3 goes low(0) which switches off the motor. When the level goes below the low level ,that is pin 2 ...

Hey Guys, I hope you are enjoying your day. let's without wasting time jump on our project. First of all you have to Bootload your Atmega Chip because newly purchased chip can't be used in Arduino . There are several ways for Bootloading your  Atmega chip like you can use a bootloader or you can also use Arduino Ide to burn bootloader in the chip . After you bootload your Atmega IC you can jump on the next part which is connection . In Figure 3 you can see how all 28 pins in Atmega chip works .For using Atmega chip the required connections are very less .You can easily program the chip using Arduino Uno and use it wherever you want ....

  Materials required-: Arduino Uno Board Bluetooth Module (JDY-30) Breadboard Led (as per your choice) jumpers Resistors (220 ohm )  Hey guys, This is our 10th project using "Arduino Uno" in this project I'm gonna show you how you can connect to a Bluetooth module and operate led . This is the similar concept used in "Home Automation" projects in upcoming posts I will show you how you can make your own Home automation system. If you guys have any doubts you can contact me through email or contact us form in menu. If you want  me to make a project based on  your ideas just let me know in the comment section.

  Materials required-: PCB Board 5V Relays( as per your choice ) Resistor (220 ohm , 1k)  Led  (equal to number of relays used) Transistor (BC547) 3 Pin Screw terminal Male header pins or Female header pins Diode (IN4007)   Subscribe How it works  ? First of all, before knowing that how relay module works you have to know that how relay works A relay is the device that open or closes the contacts to cause the operation of the other electric control Every electromechanical relay consists of  Electromagnet Mechanically movable contact Switching points and  Spring   We can control high voltages device using relays .A Relay is actually a switch which is electrically operated by an electromagnet . The electromagnet can be  activated with a low voltage , for example we can say that using a 5volts from a microcontroller and it pulls a contact to make or break a high voltage circuit. As an example for this electronics project ,I am using...

  Materials Required-: 1- Arduino Uno  2-Bread Board 3-Jumper wires 4-RGB Led 5-220 ohm resistor In this project I have used 4 RGB Led .Connection is very simple as shown below . You can use Led as per your choice, but u have to connect Led in parallel .If you have any doubts or you want me to make a project based on your idea , just let me know in the comment section or you can contact me through email.

  Material required-: Arduino Uno Breadboard jumper wires 4*Led  (used in this project) 4*220 ohm resistor  ( according to the led used) This is a very simple project in which I have used four led to make a proceeding pattern. when you  will look at  this, It looks like that they are passing their power to the next led . You can use led as per your convenience . I know, I am currently not making big projects. It's because I don't have enough materials. But I assure you, that I will definitely make a big project sooner.  If you have any doubts or you want me to make a project based on your idea,  ask me in the comment section or you can contact me from "contact us" page .I hope these projects  will help you in learning "Arduino" .
