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-->...

HELLO THERE!!!         How are you guys? I hope all of you are fine and in a good mood always.Sorry for not posting last week, been real busy submitting my partial thesis and stuff. This week, before I get deeper into Macros, I would like to introduce you guys on how to record a Macro. Basically, you don't need to code these Macros, you only need to record them and then implement them in your Excel. I would say however, there are some advantages and disadvantages on recording these macros based on my opinion. Advantages: 1. Fast 2. Do not need to code 3. Can be used for stagnant type or non changing type of application 4. Code can be modified manually Disadvantages: 1. Not Flexible to all type of applications. Ok, now let's get straight on how to record a Macro. First the requirements needed for this experiment is: SOFTWARE 1. MICROSOFT EXCEL  Well, that's pretty much the requirement needed. For the steps, let's refer to the figures below( w...
