The heart of many footstep generators is piezoelectric materials. generate an electric charge when pressure is applied. Each step produces a small amount of electricity due to the deformation of the piezoelectric material. Arduino Uno Microcontroller The Arduino Uno serves as the main controller in this setup. It collects data from the piezoelectric discs and allows for programming flexibility to monitor and manage the energy generated. With the Arduino Uno, you can program it to measure the voltage or calculate the energy generated per step. The microcontroller can also help optimize energy management by directing power to storage or by triggering LEDs or other indicators when energy is produced. The capacitor works in tandem with the Arduino Uno, where the stored energy can either be measured or directed toward a small load, like LEDs. The display, connected to the Arduino, shows important metrics like voltage, energy generated, or the total power output over time. This provides immediate feedback to users, helping them visualize the impact of their footsteps Capacitors are essential for storing the energy generated by each step Resistors play a crucial role in this setup, helping to control the flow of electricity and ensure safe and efficient operationDiodes are an essential part of this setup, as they ensure that the energy generated flows in the correct direction and is converted into a usable form diodes are arranged in a bridge rectifier circuit to convert the AC output from the piezoelectric discs into DC (direct current). This is important because DC is required to power the Arduino Uno and to store energy in batteries or capacitors. Transistors play a critical role in this setup by amplifying, switching, and controlling the flow of current to different parts of the system.
