How to make USB operated light?

Hi guys, here is very simple but useful circuit, which can be helpful when you work on laptop in Dark.

Material: One LED, 5mm size, one resistor of 300 Ohm, one USB Connector wire, and other tools like soldering iron, cutter, wire etc.

Steps

1- Connect resistor one end to the longer pin(Anode) of LED with the help of solder (you can also connect them by twisting both the pins), Now we have two pins spare, one pin of resistor and another one short leg(Cathode) of LED.

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 drive high voltage/current load by small voltage signal from a microcontroller?

Sometimes we need to control or drive a high voltage and heavy current load by a small voltage signal. For example, if you want to control water motor with your microcontroller output. We know that microcontroller gives only 5v output which is not sufficient to drive a heavy motor. This circuit, about which this post is, is very-very useful for electronics engineer and hobbyist. So pay attention! For this circuit the material we need is… General Purpose PCB - 5x5 cm. Transistor KN 2222A (TO-92) - 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. Tools. Concept: Weak signal triggers the transistor and transistor acts as a switch for the relay. You 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)....

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)...
