<p>This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.</p>

<h2><b>Photosensitive Resistor</b></h2>
<p>A high-quality LM393 voltage comparator is used in this Photosensitive Resistor Dependent Control Sensor Module. The comparator output signal produces a clean and excellent waveform when employing the sensitive type photosensitive resistance sensor.</p>
<p>With a 15mA driving capability and an adjustable potentiometer, the brightness of the light detected may be adjusted. The working voltage ranges from 3. 3 to 5 volts. Where output refers to the output of a digital switch. Because this module is light-sensitive, it is commonly used to detect ambient brightness and light intensity.</p>
<p>DO output is at a high level when there is no light or when the light intensity cannot achieve the value. The module DO output is low when the light intensity exceeds the value. The module's digital output DO can be directly connected to a microcontroller, which can detect high or low levels, allowing it to monitor changes in ambient light intensity.</p>
<p>You can use this board as a photoelectric switch or as a digital output DO port driving relay module (our store sells these relay modules). The analog output is connected to the ad module, which uses the ad-converter to obtain a more precise light intensity value.</p>

<h2><b>DS1302 Real-Time</b></h2>
<p>A real-time clock/calendar and 31 bytes of static RAM are included in the DS1302 timekeeping chip. It uses a simple serial interface to communicate with a CPU. The real-time clock/calendar displays information in seconds, minutes, hours, days, dates, months, and years. For months with fewer than 31 days, the end of the month date is automatically modified, including leap year corrections. The clock has an AM/PM indicator and works in either a 24-hour or 12-hour mode. Using a synchronous serial connection to connect the DS1302 to a microprocessor simplifies the operation. To connect with the clock/RAM, only three wires are required: CE, I/O (data line), and SCLK (serial clock).</p>
<p>Data can be sent one byte at a time or in bursts of up to 31 bytes to and from the clock/RAM. The DS1302 is designed to run on extremely little power, requiring less than 1uW to preserve data and clock information. DS1302 is DS1202's successor. The DS1302 contains dual power pins for primary and backup power supply, a programmed trickle charger for VCC1, and seven additional bytes of scratchpad memory in addition to the basic timekeeping functionality of the DS1202.</p>
