Many phenomena can be measured with simple sensors that output analog voltage value, for example, sound, light intensity, and or preasure. Therefore the Arduino offers the analog inputs (A0-A5) to read such values. To be able to detect a voltage difference (analog signal), the Arduino has a 6 channel, 10-bit analog to digital converter (AD converter). A resolution of 10-bit means that the Arduino detects a voltage difference from 0V… text/html 2026-01-09T10:02:55+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.zhdk.ch/iad/doku.php?id=electrical_engineering:digital_input&rev=1767952975&do=diff Digital Input Digital input is something with only two states: ON or OFF. In the case of the Arduino, the ON state corresponds to an electrical voltage of 5V and OFF to a voltage of 0V. On the Arduino, we mainly use the digital PINs (D0-D13) for digital circuits. However, the analogue PINs can also be used as digital pins if more inputs or outputs are required. text/html 2026-01-09T10:01:33+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.zhdk.ch/iad/doku.php?id=electrical_engineering:electronics_basics&rev=1767952893&do=diff German Version In order to use electronics and microcontrollers successfully for projects, we need to understand some electronic terms and theories. These include: Electronic Circuit: A circuit is a sequence of connected electronic components. The simplest electrical circuit consists of a power source, a load, and the connecting lines (conducting wires). Electric current can only flow in a closed circuit. In a closed circuit, the current flows from the negative pole of the power source to th… text/html 2026-01-12T10:26:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.zhdk.ch/iad/doku.php?id=electrical_engineering:transistors_as_switches&rev=1768213614&do=diff Transistors as Switches When we talk about “transistors”, we usually mean a bipolar transistor.

While most will step down a higher voltage to the desired level, some can boost a lower voltage and some can even do both. Think of it like a water pressure regulator: high, varying pressure comes in, but steady, controlled pressure comes out.
