 Creating an App to Control a Robot via Voice Command Today, we will see how to use voice commands to control a robot with an app. So, the robot works with the help of an LDR and a transistor. The robot consists of two wheels controlled by an LDR and a Transistor. The robot will have a mobile stand on top of it where the phone will be placed. The phone would've a screen where two black coloured blocks turn white according to our command, and due to its whitening, the LDR detects light, and with the help of the Transistor, the wheel would start rotating, making the robot go forward, turn right and left and stop.  We won't learn how to make the robot, but we'll learn to create an app using the MIT App Inventor to control it.  What you'll need: A Mobile Phone A Laptop Step 1: Designing the layout of our app. First, open MIT App Inventor, click 'New Project', and then rename it. Then, add Horizontal Arrangement from the Layout and change its width to 'Fill Paren...

  Using Cricut Explorer 3 to make a Custom Phone Case and Shirt Design Have you ever wished to design your own custom phone case and shirt? Well, I did. Because I've always loved the idea of having something custom-made and making something personal that I'd like. So, I opened the Cricut Design Space and started brainstorming ideas for what I could do. Then I realised I could do something related to Marvel and the Avengers. So, I decided to make a shirt print based on the Avengers logo and a phone case based on one of my favourite superheroes, Spider-Man. Making the shirt design and cutting it: Things you need: Cricut Explorer 3 Machine  A compatible device, such as a tablet or a laptop Smart Iron-On Vinyl sheet (any colour of your choice) An Iron A plain coloured shirt Butter Paper A Cricut Weeder Any design you like (The most important) Step 1: Making and finalising the design I go to Google and search for appropriate images for my design. First, I made the shirt design. I s...

 How to use an RTC to control 3 Relays Today I learned how to control 3 Relays with just an RTC and an Arduino board. This project was one of the most major projects I've done in the last few days. As I'd said in the last blog post about the project that had been done in my Father's office that had been completed, I worked on it a bit further. If you've read the last blog post, you must know that the project was about controlling the tap of the tree-watering pipe using an app and Wi-Fi. But I took it a step further when I used an RTC.  What is an RTC? RTC stands for 'Real Time Clock' which is    a specialized electronic component designed to keep track of the current date and time, even when a system is powered off, using a small battery for backup. It is used in devices which need the current value of time.👇 So, what I'd done is I took this RTC module and using an Arduino Board, I controlled 3 Relays so that at a specific time the relay should switch on an...
