Charge Controller: The charge controller will give constant output to the battery when charge controller is connected to multiple power sources.Inverter Circuit: The inverter circuit is a circuit used to convert AC power to DC power and vice versa.

A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a varying electromotive force (emf) or "voltage" in a second coil.

Transformer: A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. When voltage is applied to a piezoelectric ceramic material it causes it to vibrate rapidly, resulting in the generation of sound waves.

Battery: Battery is a device used to store the DC power.

Piezo Electric Transducer: A piezoelectric Transducer is a device that uses the piezoelectric effect, to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. I don’t want to overkill an Arduino (or Attiny/STM flakes) for the task, but I’d like to try an inexpensive Chinese one-time programmable (OTP) microcontroller (like the PM5150 by Padauk).

Solar Panel: The devices which converts the solar energy into electric energy is called Solar Panel.

You will connect your mobile with the battery through transformer and inverter circuit in order to get the AC power. The DC power generated will be stored in the battery. The charge controller will control the power obtained from both sources and will give constant power to the battery. The solar panel and piezo plate will be connected to the battery through charge controller. # include "pitches.Solar Kit will be shipped to you and you can learn and build using tutorials.

The pitches library is not found in the Arduino IDE but you can download the ZIP file from Github and include the library in the Arduino IDE by clicking in the menu line: Sketch -> Include Library -> Add.

If you take a look into the source code of the library you see that the library is nothing else than a lookup table for different notes to their frequency. You could now use the tone function and define the connected output pin, the frequency and the duration of the output generation, but if you do not know the frequency of different notes, we can also use the pitches library from Mike Putnam. Instead we use the Arduino tone function to generate a square wave of the specified frequency (and 50% duty cycle). Therefore we can not use the analog write function, because this function has a fixed frequency of 500Hz. To create a melody the passive buzzer needs an AC signal where we can define the frequency. BLOCK DIAGRAM Keywords: ARDUINO UNO, Piezoelectric sensor, IR sensor, Bridge rectifier 1. platforms, runways and these systems can be installed elsewhere. Let me know in the comment section if you know the melody that we create in this example. Footstep Power generation by using walking on the certain arrangements like stairs, footpaths, piezoelectric sensor.

The passive buzzer has the advantage that we can not only create a tone, but also a melody with different frequencies. The digital I/O pin of the Arduino, EPS8266 or ESP32 microcontroller is therefore connected to the gate of the MOSFET with a resistor of 220Ω in series, because the Arduino operation voltage of 5V or even the 3.3V operation voltage of the ESP8266 or ESP32 would damage the transistor. Otherwise we were not able to switch off a load that has a higher voltage than the control voltage. Low-side switch: The transistor is on the low (ground) side of the circuit and the buzzer is connected on the high (5V or 3.3V) side.NPN transistor: Because we want to turn the active or passive buzzer on by setting the digital pin of the microcontroller HIGH.In my case I use the IRLZ44 NPN MOSFET as low-side transistor to control the buzzer. The solution is to use a transistor and divide between the control signal and the power consumption. But if we want to use magnetic buzzers with a current consumption higher than 20mA we have to find a different power supply than the digital I/O pin of the microcontroller. Piezo buzzer have a current consumption lower than 20mA and could therefore be powered by Arduino microcontroller as well as the ESP32.
