Clock Node

#22. Clock Node

Note This is a web-version of a tutorial chapter embedded right into the XOD IDE. To get a better learning experience we recommend to install the desktop IDE or start the browser-based IDE, and you’ll see the same tutorial there.

Many tasks require you to set a specific frequency for the pulse generation.

For this, we need a new node clock. It can produce pulse signals at time intervals specified by the IVAL pin. This way, we can control the frequency of data collection from our sensors.

Try to set the IVAL pin in the clock node to 2. This means that it will send a pulse every two seconds.

Test circuit

Note The circuit is the same as for the previous lesson.

↓ Download as a Fritzing project

Slowly turn the potentiometer knob. You will see that the readings are being taken and the servo reacts to them every two seconds.
