This is the LED flashing circuit, since the shape used in this circuit was hearth shape, then we call it LED flashing heart circuit. The circuit is quite simple, low cost, easy to built. Alternatively, you could be create another shape, not just heart shape. Schematic diagram: Component list: Resistors R1, R2 – 470 ohm,… Read More »
This is the circuit diagram of drinking water alarm based a small water sensor by using aluminium foil and plastic foil, and connected to a very simple alarm based a 555 IC timer. The Jal State Board supplies water for a limited duration in a day. The time for water supply is determined by administration… Read More »
This is the circuit diagram of 12 Volts, 4 Amperes Solar Photovoltaic (PV) battery charger which will be suit to charge a 12V battery or accumulator. The circuit handles up to 4 amps of current from a solar panel, which equates to about 75 watts of power. A charging algorithm called “pulse time modulation” is… Read More »
