Calculator

The calculator is an electronic soldering kit that, when assembled, creates a fully functional school calculator with a seven-segment LED display and a push-button keyboard. The kit contains all the necessary components - a printed circuit board, segment displays, resistors, transistors, capacitors, buttons, a microprocessor, counters, a crystal and a battery holder. Thanks to the clear color instructions, the individual components can be easily installed in precisely marked places on the board, making it suitable even for beginners. After inserting the batteries and turning on the power switch, the calculator is ready to use and allows you to perform basic and more advanced mathematical calculations using the buttons on the front of the device.

The kit is ideal as a first step to understanding the function of segment LED displays, a microprocessor, buttons, and a basic power supply circuit.
