Educational board - a didactic aid - for learning and experimenting with the AtMega 2560 processor. Very easy to use thanks to the included connection cables and convenient sockets - protected against incorrect connections, allowing for the creation of a huge number of prototype devices. An ideal tool to start robotics education even from the 3rd grade of primary school. The board contains many controllable peripheral elements, whose schematics are shown on the board, and the power lines are already routed inside the board, so that beginner students cannot make a mistake that could lead to damage to the microcontroller or the actuator or sensor. The board has a built-in popular 2-line by 16-character display with an I2C converter - making display control as simple as possible. Students can check the voltages in the circuits using the built-in digital voltmeter, which also facilitates understanding of the operation of analog sensors and potentiometers. The board contains the following elements: 1. STABILIZED POWER SUPPLY 230 -> 12 V / 5 V 2. DIGITAL VOLTMETER (accuracy 0.01 V) 3. SPEAKER 4. 5 LARGE (5mm) LED DIODES - each of a different color 5. PWM SIGNAL AMPLIFYING TRANSISTOR for controlling a light bulb (as an example of an energy receiver controlled by a signal) 6. Monostable BUTTONS (3 PCS) - for any use (START, DIRECTION CHANGE, OPTION SELECTION, etc.) measurement and conversion of analog values: 7. POTENTIOMETER 8. HALL SENSOR (magnetic field sensor) 9. LIGHT INTENSITY SENSOR (photoresistor) 10. TEMPERATURE SENSOR (thermistor) 11. CARBON MONOXIDE SENSOR digital converters: 12. DIGITAL TEMPERATURE AND AIR HUMIDITY SENSOR 13. ULTRASONIC DISTANCE SENSOR 14. INFRARED PROXIMITY SENSOR 15. MOTION DETECTOR - PIR SENSOR mechanical devices: 16. NEMA 17 STEPPER MOTOR with STEPSTICK driver 17. 180-degree SERVO Also included with the device is a set of 12 double-sided banana plugs, which students can use to connect the microcontroller to the peripheral elements. Board dimensions: 59 x 40 x 5 cm The board can be used in a hanging or lying position.
