 Making a Robot That Works With the Help of an LDR What you'll need: A4 paper (White) Copper Tape Soldering Gun and Its Accessories 5 wires (At least 7-8 cm long) 2 100 RPM motors 2 Toy Tyres  2 2500 mAh batteries 1 Battery Holder 1 Switch 2 Smartphone-sized MDF Cut-outs Masking/Paper/White Tape 1- 1 cm by the width of the smartphone-sized MDF cutout. Hot Glue Gun 2 LDRs 2 PC547 Transistors  Double-sided tape Instructions: Step 1: Print the paper circuit on the A4 sheet and apply the copper tape according to the paper circuit. The PDF is provided below👇. Print the PDF for the paper circuit.  https://drive.google.com/drive/folders/1PYE8-AFwr0lTYRsBEQ-Hbiz-uuHeQL_2?usp=drive_link Step 2: Solder the LDRs and the Transistors at the given places.  Step 3: Connect the motors to the paper circuit. Then, stick the paper circuit to one of the MDF sheets with either hot or normal glue.  Step 4: Join the MDF sheet cutouts in the following way.  Take the two sma...

 Creating Two Apps to Control a Robot via Two-way Phone Bluetooth Today, we will see how to use two smartphones' bluetooths to control a robot with two apps. 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 two apps that control it using the MIT App Inventor.  What you'll need: A Mobile Phone A Laptop This time, we'll be creating two apps to control the robot. Because we'll have an app that will send messages to the other via Bluetooth on both phones. We'll fi...

Creating an App to Control a Robot with Sequential Commands   Today, we will see how to use Sequential 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 Firstly, open the MIT App Inventor and then click on 'New Project' and rename the project to 'Robot_Sequential_commands'.  After that, chan...

 Creating an App to Control a Robot via Voice Command and Gyroscope Today, we will see how to use voice commands and a Gyroscope 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 the MIT App Inventor website and click on 'New Project'. Then, rename it to 'Gyroscope_Voice_Command'.  After ...
