The AND gate is a basic digital logic gate used in electronics and computing devices. Its outputs are only true/HIGH (1) when all its inputs are true/HIGH (1). This makes it important for decision-making in circuits, helping perform tasks like calculations, controlling signals, and making comparisons. AND gates are building blocks for complex circuits like adders and multiplexers, which are key for many electronic devices. Simply, they help computers and systems make decisions based on multiple conditions.
In this blog, we will tell you how to build an AND gate using a breadboard with a 9V power supply, as we have already talked about making an AND gate.
Procedures and a step-by-step guide:
1- First, take an IC chip containing the number 74LS32. This IC has 14 pins each. Each pin has its own task.
2- But before any other work, you have to use a 5V Voltage regulator having the number LM7805 to reduce the voltage from 9V to 5V because any voltage higher than the 5V will damage the IC making it unusable.
To use the 9V regulator connect the +ve terminal of the 9V battery with the first pin of the regulator, then connect the -ve terminal of the 9V battery to the second pin. Now from the second pin again connect it to a wire from the opposite side resulting in the -ve 5 Volt supply and from the third pin you will get the +ve 5V supply.
3- Now that you have a 5V supply, install/put the IC on the breadboard and connect pin number 14 with +ve 5V and pin number 7 with -ve 5V(GND). The number configuration is given below.
4- Now, connect two switches, as one end of both switches is connected to the +ve 5V, and the other has the IC as an input, as shown in the image. As it is a 2-variable IC, it has only two inputs(pin numbers (1,2)(4,5)(13,12)(10,9)) and one output(pint numbers 3,6,11,8) that can connect it by using jumper wires.
5- Now connect the output with the +ve end of the LED light. Now use a resister of resistance 100-110ohms.
Connect one end of the resister with the -ve 5V and the other end with the LED as it will reduce the voltage and avoid damaging the LED.
6- To Check whether the Circuit is completely made or not follow the Truth Table and see if the results are accurate then it is made correctly otherwise recheck your connection for any errors.
