Dancing LEDs circuit is used for decorative purpose and looks very good when these LEDs glow in sequential manner. We can create many kind of Dancing LEDs patterns for decoration. In this particular circuit, we have created a pattern in which 6 LEDs are illuminating in forward and reverse order. To create this circuit we have mainly used 555 timer IC and 4017 IC.

The DC MOTOR SPEED CONTROL circuit is primarily a 555 IC based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained here. Consider a simple circuit as shown in figure below.
If the button is pressed if the figure, then the motor will start rotating and…
Whenever we need a constant and specific value of voltage without fluctuation we use voltage regulator IC. They provide a fixed regulated power supply. We have 78XX (7805, 7806, 7812 etc) series voltage regulators for positive power supply and 79XX for negative power supply. But what if need to vary the power supply voltage, so here we have Variable Voltage Regulator IC…
“Eyes sense what mind sees.” Like this LDR (light dependent resistor) sense if there is any light source in its sensing range. It’s true that you can manually switch OFF and ON any light, but sometime human beings shows carelessness which may cause waste of electricity. To overcome this problem, we are going to show you that how to make a Light Detector Circuit (which…
In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi.
In this RGB…
H-bridge is the circuit in which voltage can be applied across the load, in either of the direction. These circuits are frequently used in robotics, especially for the DC motor. Voltage can be applied in either direction to rotate the DC motor forward or backward. DC motor further move the robot or any robotic system, forward or backward.

In this tutorial, we will show you how to connect a Laser diode in an electronic circuit. In comparison to LED’s light, Laser light is highly concentrated, it’s have smaller and narrower viewing angle. For connecting a laser diode in an electronic circuit we need a Laser diode driver circuit.
Required Components Laser Diode module (650nm, 5mw) LM317 Voltage…
Monostable multivibrator (MMV) mode of 555 timer IC is also called Single shot mode. As the name indicates, only one state is stable and the other one is called unstable or quasi stable state. 555 timer IC remains in Stable state until the external triggering is applied. An external triggering is required for transition from Stable to unstable state. 555 IC automatically…
Raspberry Pi and Arduino are the two most popular open source boards in Electronics Community. They are not only popular among Electronics Engineers but also among school students and hobbyists, because of their Easiness and Simplicity. Even some people just started liking Electronics because of Raspberry Pi and Arduino. These boards have great powers, and one can build…
The SR flip flop using NAND gate truth table is a basic sequential logic circuit that holds one bit of digital information. This extensive guide goes over the general SR flip flop circuit diagram with explanation, a discussion of the truth table, and its implementation using IC SN74HC00N. If you want to become proficient in digital electronics and sequential circuit design, it's important to…
Reaction timer is a game to test how fast you reacts. This game which we have developed using 555 IC is for two players where first player starts the game by pressing start button. As soon as the START button is pressed, 7 segment display starts displaying 0 to 9 numbers in a high speed. Then other player stops the counting by pressing the STOP button. As the…
In this project, we will make an 8-channel Motor Driver Module Circuit for motors based applications. In this circuit, we have designed a PCB for driving DC or stepper motors. By using this motor driver board we can operate 8 DC motors or four 4-wire stepper motors at a time. In this board, we have used few three pin screw terminal blocks and burgsticks, connected from the…
