<div style="text-align: justify;">
A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels. The logic state of a terminal can, and generally does, change often, as the circuit processes data. In most logic gates, the low state is approximately zero volts (0 V), while the high state is approximately five volts positive (+5 V).</div>

Turn Off Battery Charging from Solar Panel at Nightfall

<b><span style="font-family: "arial" , "helvetica" , sans-serif; font-size: large;">Turn Off Battery Charging from Solar Panel at Nightfall</span></b></h2>
<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"></span><br />
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">When loading a battery during the day from a solar panel it can be partially discharging through the panel after nightfall. This solar panel power switch circuit replaces the diode and connects the panel to battery through a relay contact. When the power supply voltage is too low the relay is not ON, so the battery is not connected to the solar panel. When the voltage is high enough to engage the relay and the LDR receives enough light in order to open T1, the relay will switch and the battery will charge.</span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;">
<div style="text-align: justify;">
The relay remains ON even when the solar panel voltage starts to decrease. A connected and charged battery cannot action the relay when the light intensity decreases because R2 will block T1. The brightness at which this occurs is set by P1.</div>
<div style="text-align: justify;">
Because the power consumption is determined primarily by the relay, it is important that the relay should be a miniature one, with high coil resistance but also be capable to switch up to 10 Amps.</div>

<div style="text-align: justify;">
In electronics, a multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines, which are used to select which input line to send to the output. Multiplexers are mainly used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth. A multiplexer is also called a data selector. Multiplexers can also be used to implement Boolean functions of multiple variables. An electronic multiplexer makes it possible for several signals to share one device or resource, for example one A/D converter or one communication line, instead of having one device per input signal.</div>

Exclusive OR </h3>
<div style="text-align: justify;">
The XOR gate (sometimes EOR gate, or EXOR gate and pronounced as Exclusive OR gate) is a digital logic gate that implements an exclusive or; that is, a true output (1/HIGH) results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is "one or the other but not both".</div>
<div style="text-align: justify;">
XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers. A half adder consists of an XOR gate and an AND gate. Other uses include subtractors, comparators, and controlled inverters.</div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">A mathematician named DeMorgan developed a pair of important rules regarding group complementation in Boolean algebra. By group complementation, I’m referring to the complement of a group of terms, represented by a long bar over more than one variable. DeMorgan’s theorems state the same equivalence in “backward” form: that inverting the output of any gate results in the same function as the opposite type of gate (AND vs. OR) with inverted inputs. Inverting all inputs to a gate reverses that gate’s essential function from AND to OR, or vice versa, and also inverts the output. So, an OR gate with all inputs inverted (a Negative-OR gate) behaves the same as a NAND gate, and an AND gate with all inputs inverted (a Negative-AND gate) behaves the same as a NOR gate.</span></div>

The states of a digital computer typically involve binary digits which may take the form of the presence or absence of magnetic markers in a storage medium , on-off switches or relays. In digital computers, even letters, words and whole texts are represented digitally.</span></div>

Introduction and explanation of XOR gates :</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
XOR gate; The XOR gate (sometimes EOR gate, or EXOR gate and pronounced as Exclusive OR gate) is a digital logic gate that implements an exclusive or; that is, a true output (1/HIGH) results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is "one or the other but not both". XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers. A half adder consists of an XOR gate and an AND gate. Other uses include subtractors, comparators, and controlled inverters.</div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">In digital circuit theory, combinational logic (sometimes also referred to as time-independent logic is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has memory while combinational logic does not. Combinational logic requires the use of two or more gates to form a useful, complex function.</span></div>
