Analog signals – directly measurable quantities in terms of some other quantity. Examples: Thermometer – mercury height rises as temperature rises Car Speedometer – Needle moves farther right as you ...

This Arduino project involves measuring both AC and DC voltages using the ZMPT101B voltage sensor and an analog pin, respectively. The AC voltage is read from the ZMPT101B sensor connected to pin A0, ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign launched today for a new development board ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...
