ProgBlox

ProgBlox object-oriented programming without a computer.

The set is intended for children aged 5-7 years. The goal is to learn to solve more complex problems (by disassembling them into parts - objects) and with logical thinking to learn the basic steps of programming, construction and robotics.

The child's focus is directed to a part of the problem - a single object or related objects. Objects are all active parts of a model that can be controlled via a control module. Objects can be input (connected to the input of the receiving module) and output (connected to the output of the receiving module). Two programs can be arranged for each input object. One program is for the state when the input object has a signal (ON), and the other for the state when the input object has no signal (OFF). Such programs are called object programs. In addition to object programs, the states of output objects can also be controlled through the main program.
