Encoder and servo 6

In this activity you’ll learn how to control a servomotor with an encoder. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital signal.

Seven segment display 4

In this activity you’ll learn how to show something on a seven segment display. In order to make it easier to use the display, we’ll use a library. 


Temp and hum sensor 3

In this activity you’ll read the ambient temperature and humidity with a DHT11 sensor brick. In order to use the sensor, you’ll need a library. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data.
