LDR sensor

 LDR Sensor

Today, I made a circuit using an LDR(Light Detecting Resistor) sensor. An LDR sensor works on the amount of light present.
To make this circuit, we need the following things:
  1. LDR sensor
  2. Breadboard
  3. LED
  4. Buzzer
  5. Jumper wires
  6. 9V battery
To make the circuit, follow the following steps:
    Step 1: Connect the positive and negative terminals on the breadboard to make them common.
    Step 2: Connect the VCC of the sensor to the common positive on the breadboard.
    Step 3: Connect the GND of the sensor to the common negative on the breadboard.
    Step 4: Connect the negative of the LED and the Buzzer to a vertically connected line.
    Step 5: Connect the positive of the LED and the Buzzer to the common positive line.
    Step 6: Connect the DO(Data output)of the sensor to the line where the negative of the LED and the Buzzer are on the breadboard.
    Step 7: Now connect the negative and positive terminals of the battery to the common points on the breadboard.

DIY Lab

DIY Lab My name is Tejas. I am in 7th grade. I have been a member for DIY lab since the last 1 year. Here at DIY lab, we do many different things & projects. There is a verity of tools like 3d printers, Lazer cutter, vinyl cutter, etc. I have done quite a lot of projects myself. I have used many electrical components here, like some microcontrollers, breadboard, jumper wires, and many more.  I got to know about these instruments because of DIY lab. The best thing abought it is that it is open every day. It is because of DIY lab that I got to know how different things work. I also got to know about many software that I could not have learn anywhere else. If you have an idea, they can help you make it come to life. I have done block coding, made games and even made working robots. We have taken things apart, learnt how they worked & put them back together. I remember coming here for the first time and seeing all the different things that I couldn't have seen if I would have c...

Python coding(calculator)

Python code calculator   Today, we made a calculator using Python code. We did the coding on an online Python compiler called Programiz Python compiler. We used the "if" function to decide which code to run. There were four separate parts of the code to carry out different operations. When we press the "Run" button, it asks us to enter any of the four mathematical operations. Once we enter the operation, we need to enter two numbers. These numbers have to be integers only, or the code will have an error. The "while(True)" function keeps the code running after doing one operation. Code: while (True):     print("Enter operation:")     c =str (input())          if c=="+" :         print("Enter number a:")         a=int(input())         print("Enter number b:")         b=int(input())         add=a+b         print("Addition ...
