How to make very simple Water Sensor Circuit?

Hi folks, today I am going to discuss about water sensor circuit

Water Sensor Circuit


Material:
1.    General Purpose PCB 2x2 inch.
2.    Resistor: 10K                     ---------- 2 Nos.
3.    Resistor: 15K                     ----------1 No.
4.    Resistor: 1K                       ----------1 No.
5.    Transistor: 2222A              ---------- 2 Nos.

How to Make Automatic Room Light Controller Without Microcontroller

You must have noticed in some offices or hotels, when nobody is in gallery or washroom, the light remains OFF but when somebody enters the place, light switches ON automatically. In this post I am going to teach you how to make this circuit. Before going ahead I would like to tell you that this is VERY EASY circuit. For this circuit the material we need is… PIR Motion sensor General Purpose PCB - 5x5 cm. Transistor 2222N – 1 No. Relay 5V – 1 No. 1K/0.250W – 2 Nos. 10K/0.250W – 1 No. IN4007 – 2 Nos. LED 3mm – 1 No. Connector – 4 Nos. Few wires. Relay Circuit Concept : We can use any relay of 12V, 24V, 5V etc. but we have to consider power supply or battery we will use. Since 5V power supply is easily available and 9V battery can also be used for 5V output (after using 7805 regulator if needed). So I am using 5V relay. PIR sensor has three terminals, One for 5Vdc Second for Gnd (0V). Third for ...

How to control digital output with serial monitor in Arduino

Hello Friends, in this blog we will be controlling digital output with serial monitor command. First let’s understand the working of serial monitor. Serial monitor in Arduino IDE is a tool which allows communication between the computer and Arduino board via a serial connection, normally we use USB cable for connection. What are the features of Serial Monitor? It shows the data sent from the Arduino board by using the functions like Serial.print() or Serial.println(). It allows to send text or numeric data to the Arduino board, which can be read by function like, Serial.read() or Serial.parseInt(), thereafter you can use this data for further analysis and action. We can use this tool for debugging and monitoring the function of the sketch. There is a procedure to use the serial monitor, below are the steps given. First initialize the serial communication in the sketch as given below. Normally baud rate is set 9600.  Void setup(){          Serial.begin(9600)...

AND Logic Gate by Transistors

Creating an AND gate using transistors is a fundamental exercise in digital electronics. In this post, I will guide you through the process of building an AND gate with transistors, explaining each step in detail.   What is an AND Gate? An AND gate is a basic digital logic gate that outputs TRUE or HIGH (1) only when all its inputs are true or high. If any of the inputs are false or low (0), the output is false or low (0). The truth table for a two-input AND gate is as follows: Input A Input B Output 0 0 0 0 1 0 1 0 0 1 1 1   Components Needed To build an AND gate, you will need the following components: NPN Transistors: BC547 (2 Nos.); Q1, Q2. Resistors : 10K (2 Nos) - R1, R2. Resistors : 1K (1 No) - R3. LED: 5mm Red (1 No) – L1, for output indication. Switches: ...
