The Tinker Hut

HELLO THERE!!!       How are you guys? I hope everyone is fine and in good mood always. This week, I wanted to show you guys an experiment I made throughout the weekend. Continuation of last week's experiment, this week, I decided to make a graph out of my output and log the data into a SDcard. Let's get to the specifics without wasting any further time. HARDWARE: 1.Arduino UNO 2.Big Sound Sensor 3. Ethernet Shield/ MicroSD Shield/ Any board with Micro SD slot ( I used and will concentrate the ethernet Shield for this post) 4.MicroSD Card SOFTWARE: 1.Arduino IDE 2.Processing IDE (download here:https://processing.org/download/) CIRCUIT ASSEMBLY: OK,  the circuit is assembled as follows: 1. Plug in the Ethernet Shield on top of your Arduino 2. Connect the Big Sound sensor as follows: SENSOR                                   ARDUINO A0 ...

HELLO THERE!!!         How are you guys? I hope everyone is fine and good always. This week I would like share with you guys an experiment on arduino and big sound sensor (also known as sound sensor). The objective of this experiment to control a LED brightness by using the sound sensor.  So, without any delays, let's jump in to the experiment!!!! HARDWARE: 1.Arduino UNO 2. LED(you can also use the LED in Arduino itself) 3.Big Sound Sensor SOFTWARE: 1.Arduino IDE CIRCUIT ASSEMBLY 1.  Connect the LED to the Arduino. The long leg(+ve) to the pin 13(or any other digital pin) and the short leg(-ve) to GND 2. For the big sound let's refer to the image below:    From the image shown, there are 4 pins, A0(analog pin), D0(digital pin), +(+ve pin), G(GND pin). So, we are going to use the analog pin in this experiment, the assembly is as follows: SENSOR               ...

HELLO THERE!!    How are you guys? As usual, I hope everyone is fine and in good mood always. This week, I would like to share with you guys a simple system I made through out the weekend, a simple bluetooth door lock. Without further wasting our time, let's get straight to requirements of the system. HARDWARE: 1. ARDUINO UNO 2. HC-06 BLUETOOTH MODULE 3.SERVO MOTOR 4.DOOR LATCH/DOOR LOCK( I used the door lock as shown in the image below) 5.THIN GAUGE WIRE/THIN STEEL WIRE/ KEYCHAIN RING SOFTWARE: 1. ARDUINO IDE 2.MIT APP INVENTOR CIRCUIT ASSEMBLY:   What  I did first is to tie or attach the servo motor to the latch as shown in the image below . After tying in the servo with the latch, the servo must be put in a suitable position( preferably in the middle of the latch) so that the open/close motion can be achieved properly. The connection of the servo with other peripherals of the circuit is shown below: COD...

HELLO THERE!!!!!    How are you guys? I hope everyone is fine and in good mood always. This week, I continue my tinkerings with the Multi Function Shield. In this experiment, I used the potentiometer in the shield to control the LEDs in the shield. Without further wasting time, let's jump in straight to the experiment!! HARDWARE 1.ARDUINO UNO  2.MULTI-FUNCTION SHIELD SOFTWARE: 1. ARDUINO IDE CIRCUIT ASSEMBLY    The circuit assembly is fairly simple. Just attach the multi function shield on top of Arduino properly. Please attach the shield properly as failure to do so would cause the shield  not to function as intended. CODING THE ARDUINO: Let's refer to the multi-function shield image below: Referring to the image of the shield, it can be seen that the potentiometer (blue object near buttons) is connected to pin A0 (analog 0)     int pot = A0; //declaring the pot ...

HELLO THERE!!!      How are you guys? I hope everyone is fine and in a good mood always. First of all, I would like to ask for forgiveness because I had suddenly stopped tinkering for about a month. This is due to me landing my first job (YeaYYY!!). So, I am currently in process of rearranging my schedule to fit my time. After this, I would try to post my tinkerings on every weekends.       So, this week, I would like to share with you guys a simple experiment on arduino and multi function shield. I will be showing you guys on how to blink all the LEDs in the multi function shield. Without further wasting time, let's get straight to experiment!!!   HARDWARE: 1. Arduino UNO 2.Multi-Function Shield SOFTWARE 1. Arduino IDE CIRCUIT ASSEMBLY    The circuit assembly is fairly simple. Just attach the multi function shield on top of Arduino properly. Please attach the shield properly as failure to do so would cause the sh...

HELLO THERE!!!         How are you guys? I hope everyone is fine and in good condition always. This week, I would like to share with you guys a simple experiment I made over the weekend.The objective of this experiment is to print out characters typed from keyboard to LCD keypad Shield attached on top Arduino. Let's get straight to the items used: HARDWARE: 1.Arduino UNO 2.LCD Keypad Shield SOFTWARE: 1.Arduino IDE      The assembly for the circuit is fairly simple. Just carefully attach the lcd keypad shield on top of the Arduino. Make sure all of the shield pins were correctly connected into the Arduino pins. After assembly, power up your arduino, if everything is connected correctly, the PWR led of the shield will light up.      Now that the assembly is done, let's view the code: #include<LiquidCrystal.h> // import the liquid crystal lib LiquidCrystal lcd(8, 9, 4, 5, 6, 7); //the lcd pins in o...

HELLO THERE!!!   How are you, guys? I hope everyone is fine and in good condition always. Alright, this week, I wanted to share with you guys on a system that I made over the weekend. It is called the Automatic Plant Watering System. Without wasting more time, lets see the hardware and software needed in making this system. HARDWARE: 1. Arduino UNO 2.DC Water pump.(My water pump is exactly as below) 3.A relay(single channel) 4. A soil moisture sensor SOFTWARE: 1. Arduino UNO  Ok now that all the items had been listed lets see the overall assembly of the circuit. I am sorry as my assembly of the circuit is a bit messy: Don't worry... I will do my best to explain the circuit.. I'll divide the system into two circuits: 1. The soil moisture part The soil moisture sensor usually comes with 4 pins (VCC,GND,A0(analog pin),D0(digital pin)). In this system I had used the VCC,GND, and A0 pins: From soil moisture to Arduino: VCC-->5V GND-->...
