![]() ![]() Programming in the Arduino Uno is carried out specifically in the integrated development environment (IDE). Easily programmable is the biggest advantage of other microprocessors. It can be easily programmed with Arduino libraries. The most popular Arduino card is the Arduino UNO model shown in Figure 2. Arduino Uno uses the ATmega328 microprocessor. This event is notified by a glowing LED beneath the weighing machine.Īrduino Uno is the robot's brain. (Also one can hear the switching sound of the relay)Thus, whenever a person walks through a weighing machine the battery gets charged due to the voltage which is also displayed on the voltmeter. This event is notified by a glowing LED on the PCB. LED’s have been mounted under the weighing machine that is switched on by relay through 555 timer IC whenever a voltage is generated. ![]() Also, at the same time, this voltage is used to charge the 12V DC Battery. This voltage is sensed by a voltmeter and displayed on its display. Thus a full vibration is sensed by a crystal disc and a voltage across it is produced. After the leg is lifted a crystal is decompressed. When one steps on a weighing machine the piezoelectric disc gets compressed. ![]() In this project, we have used the same phenomenon of producing piezoelectricity from the piezoelectric crystal in the form of a coin shape disc. By squeezing a crystal, you have produced the voltage across its opposite faces and that's piezoelectricity. Now the effects of the charges are no longer eliminated one another out and net positive and negative charges appear on opposite crystal faces. If you squeeze the crystal (massively exaggerated in this picture!), you force the charges out of balance. Normally, the charges in the piezoelectric crystal are exactly balanced, even if they are not symmetrically arranged. This effect carries through a whole structure so net positive and negative charges appear on the opposite, outer faces of the crystal. However, if you squeeze or stretch the piezoelectric crystal, you deform the structure, negative, and causing net electrical charges to appear. Normally, the piezoelectric crystals are electrically neutral and atoms inside the piezoelectric plate may not be symmetrically arranged, but their electrical charges are perfectly balanced, the positive charge in one place cancels out a negative charge nearby them. In most crystals, the unit cell is symmetrical in piezoelectric crystals. Thus, squeeze certain crystals and you can make electricity flow through them. Piezoelectric Effect is the ability of certain materials for generating electric charges in response to applied mechanical stress on the piezoelectric plate. The Footstep power generator works on the principle of piezoelectric effect impact. Our project model cost is effective and easy to implement and also it is green and not harmful to the environment. Thus we charge a battery using power from footsteps, display it on LCD using a microcontroller circuit and allow for mobile chargin through the setup. The current is distributed using (radio-frequency identification) RFID cards so that only an authorized person can use the generator for charging. Also, it consists of a USB mobile phone charging point where a user may connect cables to charge the mobile phone from the battery charge. It also displays the charge generated by our footstep and displays it on an LCD. The circuit is the microcontroller based monitoring circuit that allows users to monitor the charges and voltage a connected battery to it and this power source has many applications. This is then forwarded to our monitoring circuitry. To generate maximum output voltage the sensors are placed in such an arrangement. To generate a voltage from footstep the piezo sensors are mounted below the platform. an advanced footstep power generation system proposed here uses the piezoelectric sensors. To generate the power through footsteps as a source of renewable energy sources that we can obtain while walking on a certain arrangement like stepping foot on piezoelectric tiles. Energy harvesting is defined as capturing minuteamounts of energy from one or more of the surrounding energy resources. The benefits of roadway energy harvesting systems are potentially excellent. To comfort our daily routines the devices are used in large numbers. Utilization of power turns to be necessary for every work in today's world. ![]()
