ELECTRONICS

Each segment in the display module is multiplexed, meaning it shares the same anode connection points. And each of the four digits in the module have their own common cathode connection point. This allows each digit to be turned on or off independently. Also, this multiplexing technique turns the massive amount of micro controller pins necessary to control a display into just eleven or twelve (in place of thirty-two)!

• The 555 timer IC is an integrated Circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package.

• It is used to connect a 9V battery to the application. This snap power cable to DC 9V clip male line battery adapter for mostly used to power Arduino boards.
• The connector comes with open wire at one end and battery connector at another end. It is very good practice to use such connector in the project as they provide various benefit such as avoid short circuits, No chance of mismatch polarity as wire comes in red and Black colour, optimum battery use, easy to connect and disconnect the battery to the application etc.

• This module can be configured in a transmitter or receiver, the transmitter could be paired with the receiver, the receiver and the receiver or the transmitter and the transmitter can not communicate between when buying, the default value for the receiver.
• It uses the conventional Bluetooth chip CSR, Bluetooth V2.0 protocol standards.

Color Recognition Sensor is a small module designed with TCS3200 Color Sensor that can convert light intensity to frequency. … Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.

• This is 40 pins single row female berg strip/header. It can be cut into any desired sizes with the wire cutter. The pitch for this header is standard 2.0 mm.

Flex sensors are usually available in two sizes. One is 2.2 inch and another is 4.5 inch. Although the sizes are different the basic function remains the same. They are also divided based on resistance. There are LOW resistance, MEDIUM resistance and HIGH resistance types. Choose the appropriate type depending on requirement.  Here we are going to discuss 2.2inch Flex sensor that is FS-L-0055.

The joystick module, like a controller for a game console, allows you to control X, Y, and Z dimensions. Data types X and Y serve as analog input signals, allowing them to measure different levels of resistance.

4 x 4 keypad module is a module with 16 buttons and each button has a character, number, and symbols. This keypad module is used in input projects.
