Invented in Ukraine

The system of neuropsychological development and correction «Ambidexter» on the NodeMCU platform

System scope:

— tool for practical psychologists and speech pathologists when working with children with special needs

— simulator for the development of connections between the hemispheres of the brain for children and adults

— simulator game for early childhood development

— an exercise machine to improve the neural connections of the elderly

— rehabilitation tool after injuries and brain diseases, violations after wounded.

The principle of operation:

The LEDs on the panels light up according to the developed exercises. The child’s task is to cover the illuminated LEDs with his fingers, with his left hand on the left panel, with his right hand on the right.

Or use the principle of «crossed hands»: cover the LEDs on the right panel with the left hand, and on the left panel with the right hand.

The distance between the panels and the switching speed of the LEDs are adjustable, you can use panels with LEDs of different colors.

Technical details:

The system consists of a NodeMCU controller and two MAX7219 LED panels.

The system is controlled from a smartphone via Wi-Fi. The connection to the web server of the system is made using the smartphone browser and allows you to change exercises and control the speed of switching LEDs.

The system is powered by 5 volts, which makes it mobile and electrically safe.

The cost of NodeMCU and two MAX7219 LED panels on Chinese trading platforms does not exceed $ 12, including delivery to Ukraine.

The project used Adafruit GFX Library and Max72xxPanel libraries.

The system was developed for the first time, based on your own idea.
