Here we are going to design a prototype for Automatic Bottle Filling Machine using Arduino Uno, conveyor belt, solenoid valve, IR sensor, and Stepper motor. Belt conveyor is driven by a stepper motor at a constant preset speed. The stepper motor will keep driving the belt until an IR sensor detects the presence of a bottle on the belt. We used the IR sensor as an external trigger. So whenever the IR sensor goes high it sends a trigger to Arduino to stop the motor and turn on the solenoid valve.

VL6180 differs from other distance sensors as it uses a precise clock to measure the time taken by the light to reflect back from any surface. This gives VL6180 a benefit over other sensors because it’s more accurate and immune to noise.

Simple Wireless Power Transmission Circuit to Glow an LED
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.

In simple Op-Amp applications, the output is proportional to the input amplitude. But when op-amp is configured as an integrator, the duration of the input signal is also considered. Therefore, an op-amp based integrator can perform mathematical integration with respect to time. The integrator produces an output voltage across the op-amp, which is directly proportional to the integral of the input voltage; therefore the output is dependent on the input voltage over a period of time.

Simple H-Bridge Motor Driver Circuit using MOSFET
At the outset driving a motor might seems like an easy task – just hook the motor up to the appropriate voltage rail and it will start rotating. But this is not the perfect way to drive a motor especially when there are other components involved in the circuit. Here we will discuss one of the most commonly used and efficient way to drive DC motors – H-Bridge circuit: https://circuitdigest.com/electronic-circuits/simple-h-bridge-motor-driver-circuit-using-mosfet
Frequency to voltage converter converts the frequencies or pulses to the proportional electrical output such as voltage or current. It is an important tool for electromechanical measurements where repeated events are occurring. So, when we provide a frequency across a frequency to voltage converter circuit, it will provide a proportional DC output. Here we are using KA331 IC to build a frequency to voltage converter circuit.
