Presented here is an Arduino based audio meter that uses a liquid crystal display (LCD). A VU meter or standard volume indicator (SVI) is a device that displays a representation of signal level in audio equipment. In this project, the intensity of left-channel and right-channel audio signals provided as input to Arduino UNO board is displayed as

Motor starter reduces the load, torque and current surge of a motor during startup. On starting, the motor takes more than five times the normal running current. This overheats the motor’s armature winding and creates a sudden voltage dip in the power supply, which can be avoided by using a motor starter. There are many

Here we describe interfacing of three 16×2 LCDs with common data lines to an Arduino Uno board. Four data lines of all the three LCDs are connected to digital pins of the Arduino Uno board but data displayed on each LCD is different. Circuit and working The circuit diagram for interfacing of three LCDs with
