-  * The value of the resistance of the potentiometer is displayed on the LCD in ohms when the resistance of potentiometer is below 1000 Ω and kilo-ohms when above 1000 ΩThe nominal value of the resistance is 10 kΩ. Results show in the correct units, ohm mark as (Ohm).+  * O valor da resistência do potenciómetro é exibido no LCD em ohms quando a resistência do potenciómetro está abaixo de 1000 Ω kilo-ohms quando acima de 1000 ohmsO valor nominal da resistência é de 10 kΩ. Os resultados são mostrados nas unidades corretas, ohm como (Ohm).

-  - Measuring the distance to an objectThe distance to an object is measured with an IR sensor by pressing the button S1. During the measuring yellow LED is blinkedIf the object is beyond 50 cm a green LED is lit and when the object is closer than 50 cm a red LED is lit.+  - Medir a distância a um objectoA distância a um objecto é medida com um sensor de infravermelhos, premindo o botão S1. Durante a medição o LED amarelo piscaSe o objeto está além de 50 cm, o LED verde acende-se, enquanto qu se o objeto está mais próximo que 50 cm é o LED vermelho que se acende.
   - The distance to an object is measured using an UH sensor. The result is displayed  on the 7 segment display. If the distance is growing,  the displayed value must grow respectively. The scale should be in decimetres (dm).   - The distance to an object is measured using an UH sensor. The result is displayed  on the 7 segment display.

   - The value of the NTC temperature sensor is displayed on the LCD in degrees. By pressing the S2 button the units may be selected: Kelvin (K), Fahrenheit (F) and Celsius (C). The temperature is displayed in correct units and symbols.   - The value of the NTC temperature sensor is displayed on the LCD in degrees.

   - Using the acceleration sensor detect the movement of an object and the direction of movement, which is displayed on a stripe with direction of the center of the LCD. The stripe length corresponds to the absolute value of the acceleration.   - Using the acceleration sensor detect the movement of an object and the direction of movement, which is displayed on a stripe with direction of the center of the LCD.
