Arduino can get damage if voltage greater than 5v is fed to it. Hence a 5v zener diode is connected to ensure safety of Arduino which breakdowns in case this voltage exceeded 5v. Working of Arduino ...

When AC mains power is on, step-down transformer X1 generates about 15V AC and converts it to above 18V DC after rectification and filtering. DC voltage thus available is split into two: one for ...

This library supports ACS712 current sensor modules of 5A, 20A, and 30A. The ACS712 current sensor module is a fully integrated, hall-effect-based linear current measuring device. It can measure both ...

Using the 4N25 as shown, it’s surprising the internal LED has not failed. Opto coupler LEDS like all LEDs require current limiting. Used in an AC circuit a reverse connected diode must be connected to ...

The Mosquito Magnet Pioneer runs off AC power via an external transformer that outputs 12 V AC. The watchdog device consists of an Arduino microcontroller, a relay module and an AC current sensor ...

Among them, the converter transformer, as an important equipment connecting AC and DC systems. It is necessary to research its operating characteristics under different working conditions. AC ...
