Entry Level Door Monitoring Alarm System

Alright! So the idea struck out of blue one day when I was shocked to see someone sitting outside my office enjoying reading a newspaper!

I had no idea who this person was, when did he come and since how long was he enjoying his unsolicited stay just outside my cabin? You must be thinking what a fool I am but you gotta trust me on this, my office is one of the creepiest that one can get anywhere. Seriously!

I had an Arduino UNO clone ready at my disposal. So, all that I needed was an ultrasound sensor, and a Buzzer. Rest of the steps, circuit assemblies, software code are ensued in this tutorial. I hope this would excite few electronics newbies out there.

Arduino Bluetooth RC Car ( Arduino Phone Controlled)


In this project, I will show you how to transform an RC toy car to Bluetooth controlled through your Android smartphone.


Step 1: What You Need?

1 x USB Type-B Cable
1 x L293D Motor Driver
1 x HC-06 Bluetooth Module 
1 x RC Car that can fit all components 
1 x Computer with Arduino IDE installed
1 x Mini Breadboard 
Male-to-Male Jumper Wires 
Female-to-Male Jumper Wires
Power: 
4 x 1.5V AA Battery  or 
1 x LiOn Rechargeable Battery ( I used an 12V LiOn rechargeable battery)
1 x 4xAA Battery Holder (for AA battery)


Before starting, remove the existing rc circuit.

Now, with one battery AA 1.5V you must find the polarity of 2 c motors.
  • For movement motor (back side) the positive polarity cable will be that moves the car forward.
  • For direction motor (front side) the positive polarity cable will be that moves the wheels left.



Step 3: Build Your Circuit.


Ι suggest you to build your circuit on Mini breadboard first.

You can use on/off switch of car like this:
Battery +........./ .......... Arduino Vin

Tip

If you have a "big" RC car it will need more power so you can use L298 module board. L293D motor driver will give max 0.5A per channel and it will be come very hot after while. L298 module board has a heat sink and can give 1A per channel, but is bigger than L293D.


Step 4: Upload Code To Board.


Download and open file with Arduino IDE. Read every line of code (+comments) to understand how it's working and then upload it to your Arduino uno board!


Step 5: Android Bluetooth Controller.


To control your new Bluetooth car, download and install this android application:

Tip

First enable Bluetooth and establish connection with BT module.
(ex. HC-06, password 1234)
Use "Help & info" button if you can not understand how it is working.

Accelelometer function is under developing, use with attention!

If you have problem with this app on your android device you can also use this one.


Step 6: Test Your Android Bluetooth RC Car. 


Video is in Greek language but I believe that you can understand it...

Thanks for watching!!!

Remember that Bluetooth technology will give you max 15-20 meters of control.

Play a Melody using the tone() function


This example shows how to use the tone() command to generate notes. It plays a little melody you may have heard before.

Step 1: What You Need?

1 x Arduino Board (Arduino UNO used in this tutorial)
1 x Piezo Buzzer or Speaker
Male-to-Male Jumper Wires 
Female-to-Male Jumper Wires (For Buzzer)

 Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.



Step 3: Upload The Code.

1. Select the Arduino board type: Select Tools >> Board >> Select your correct Arduino board used.


2. Find the port number by accessing device manager on Windows. See the section Port (COM&LPT) and look for an open port named "Arduino Uno (COMxx)". If you are using a different board, you will find a name accordingly. What matters is the xx in COMxx part. In my case, it's COM3. So my port number is 3.

Select the right port: Tools >> Port >> Select the port number.
3. You can find this code in the example of Arduino IDE.
Select File >> Examples >> 02.Digital >> toneMelody


Click press the "upload" button (see the button with right arrow mark).
The code below uses an extra file, pitches.h. This file contains all the pitch values for typical notes. For example, NOTE_C4 is middle C. NOTE_FS4 is F sharp, and so forth. This note table was originally written by Brett Hagman, on whose work the tone() command was based. You may find it useful for whenever you want to make musical notes.

To make the pitches.h file, either click on the button just below the serial monitor icon and choose "New Tab", or use Ctrl+Shift+N. Then paste in the pitches.h code.

Arduino PIR Motion Sensor Alarm (Simple)


In this project, we'll build a motion-sensing arduino alarm using a PIR (passive infrared) sensor and an Arduino UNO. This is a great way to learn the basics of using digital input (from the sensor) and output (in this case, to a noisy buzzer) on Arduino board. 

This Arduino alarm is handy for booby traps and practical jokes, and it's just what you'll need to detect a zombie invasion! Plus, it's all built on a breadboard, so no soldering required!

1 x Computer with Arduino IDE software


Don't have components? Don't worry. Just click the component's name.

Step 2: Wire Arduino Board To Breadboard.

- Connect digital input/output (I/O) pin 2 on the Arduino UNO to row 1 on the breadboard. (Green color wire)
- Connect the 5V pin on the Arduino UNO to row 2 on the breadboard (Red color wire), and connect a nearby ground (GND) pin to row 3 (Orange color wire).


Step 3: Connect Your Motion Sensor. 

- Find the Gnd (-), Vcc (+), Output pins on the PIR sensor. 


- Plug the PIR sensor into the breadboard so that its (-) pin connects to the Gnd row, its (+) pin connects to 5V, and its Output pin connects to digital pin 2. 


 (NOTE: If you have a different sensor that the one shown here, you may need to extend the sensor's pins with a stacking female header, wires, interconnect cables, etc. to fit.)

Step 4: Plug In the LED. 

- Plug the LED's anode (longer leg) into digital pin 13 on the Arduino. 
- Plug the LED's cathode (shorter leg, and/or the leg on the flattened side of the LED base) into the adjacent ground (Gnd) pin on the Arduino. 


Step 5: Connect The Piezo Buzzer. 

- Connect the Vcc on the Buzzer (Red color wire in image) to the Arduino's digital pin 10. 
- Connect the Gnd on the Buzzer (Black color wire in image) to the Arduino's Gnd pin.

(NOTE: These two wires can be reversed, as the polarity of the buzzer doesn't matter.)



Step 6: Program the Arduino. 

- Plug the USB cable into your computer and Arduino UNO. 
- Set the board and port settings for your Arduino Board.
      Board: Arduino UNO
- Open the sketch and upload to board. 


Step 7:Test Your Alarm. 

- When you power up your alarm, the PIR sensor will glow an ominous red. Stand very still or leave the room while the alarm calibrates the infrared level reading for the room. 
- Now test it by moving: the buzzer will buzz and the LED will light up. 
- Be amazed! Your PIR Sensor Arduino Alarm can sense movement up to 20 feet away. 
(NOTE: Might not be reliable for detecting the undead.)

Arduino Based Obstacle Avoiding Robot


The concept of this project is same as the Detecting Ostacles and HC-SR04 Ultrasonic Sensor.
If the robot detects an object in front of it, with the help of a small servo motor, it scans the area left and right in order to find the best way to turn. It has a notification LED, an buzzer to play a tone when an object is detected and an button for changing the function of the robot (stopped / moving forward). 


Step 1: What You Need?

1 x Micro Servo Motor
1 x Button
1 x Red LED
1 x 220 Ohm Resistor
1 x 9V Battery Holder
1 x Buzzer
8 x Nuts 
8 x Screws 
1 x Smart Robot Car Stainless Steel Metal Robot Chassis Kit 
8 x Spacers (Male-Female)
1 x USB Arduino Cable
1 x 9V Battery 
1 x Computer with Arduino Software installed 
Super Glue
Screw Drive

Optional 
HC-SR04 Ultrasonic Sensor Holder
Hot Gun Glue

Don't have components? Don't worry. Just click the component's name. 

Step 2:Put Hardware Parts On Robot Car


Use the spacers, screws and nuts to attach the Arduino UNO board and the L298 module on robot car. The mini breadboard can be easily attached on the robot car with the adhesive tape that already have at the bottom of it. 

Step 3: The 'Eyes' Of Your Robot


Use super glue to attach the servo motor in the front side of your robot. Watch the first image to understand how to put the ultrasonic sensor in the servo motor by using a small gear piece. The second image shows the completed part that will be the 'eyes' of your robot. 













Step 4: Connect The Circuit


The connections are pretty easy, watch the image above with the breadboard circuit schematic. 

(Tips: Use the breadboard only for the LED, button and buzzer, this will keep it simple and you can use the remain area to add more stuff on the future.)

Step 6: Upload Code To Robot


Plug an battery on it and press the function button once, your robot will start moving forward after upload the code to robot. To stop it, just press the button for one more time. 


You can press the 'Edit' button and start making your modification in the sketch. 
For example, try to change the '10'cm value that is the distance that will make the robot to stop and 'look' for a clear path. 

 [Note: If your robot doesn't move forward, try to change the pins of the motors (motorA1 and motorA2 or motorB1 and motorB2)].
