Relay module DIY Reverse Engineering

A relay module is a set of components that is electrically operated and works based on a signal. That can be connected to an Arduino or a transistor and or any other application that the output is a signal or a voltage. Same as relay the relay module is used to control high voltage electronic devices. A Relay module is a mechanical switch which is electrically operated by an electromagnet. When the electromagnet is activated with a low voltage, that can be 5 v, 12 v, 32 v, … it will triggers a mechanical arm that pulls a contact to make a connection between two contacts. Relay modules are used for high voltage controls, and big loads. Relay modules has low power lose in a circuit. In other hands they are slow and they are not quick as transistors.
MILLIMETRE TO CENTIMETRE CALCULATOR

Millimetre online conversion form

The millimetre (international spelling as used by the International Bureau of Weights and Measures; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre.
MILLIMETRE TO CENTIMETRE CALCULATOR

Millimetre to Centimetre Conversion

The millimetre (international spelling as used by the International Bureau of Weights and Measures; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre. One millimetre is equal to 1000 micrometres or 1000000 nanometres. Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is therfore equal to exactly ​5⁄127 (≈ 0.03937) of an inch.

Centimetre to Metre Conversion

A centimetre (international spelling as used by the International Bureau of Weights and Measures; symbol cm) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a metre, centi being the SI prefix for a factor of 1/100.[1] The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units. Though for many physical quantities, SI prefixes for factors of 103—like milli- and kilo-—are often preferred by technicians, the centimetre remains a practical unit of length for many everyday measurements. A centimetre is approximately the width of the fingernail of an average adult person
