The filter does not completely smooth out the waves to nothing but it does reduce them considerably. The output from this part is unregulated power. Regulator A voltage regulator reduces the ripple voltages left by the filter getting rid of any voltage surges or drops that could damage devices plugged into the power supply.

Nov 25 2018 I2c Inter integrated circuit is a two wire bidirectional protocol used for an exchange of data between different devices on the same bus. I2c uses 7 bit or 10 bit address allowing to connect up to 1024 devices. But it requires clock signal for generating start and stop conditions. The advantage is it provides data transfer at 400 kbps.
Mar 12 2020 A load cell or loadcell is a transducer which converts force into a measurable electrical output. Although there are many varieties of force sensors strain gauge load cells are the most commonly used type. Except for certain laboratories where precision mechanical balances are still used strain gauge load cells dominate the weighing industry.

Jan 11 2012 The circuit drawn pertains to a regular industrial UPS Uninterruptible Power Supply which shows how the batteries take control during an outage in electrical supply or variation beyond the normal limits of the voltage line without disruption on the operation providing a steady regulated output 5 Volts by LM7805 and an unregulated supply 12 Volts .
To disconnect the cable use the tip of a spudger or your fingernail to flip up the small locking flap. Then you can safely pull the cable out. Be sure to pry up on the hinged flap not the connector socket. The white line on this ribbon cable marks the edge of the connection area. To reinstall insert the cable into the connector up to this
