I started working on a project with involves Atmega162 to be programmed in order to achieve the desired output. I started to write code using Atmel studio ide but I found it very hard to work with the Atmel studio ide. Atmel studio is slow and finding bugs etc is also very difficult. So I…
Keypad-controlled and industrial gas monitoring wireless robot
In factories and industries it is common to deal with the use of harmful and poisonous gases. There are situations in which the concentration and volume of these type of gases need to be monitored in an apparatus. Because these gases can be harmful to humans, it is not safe to employ humans for such tasks.So, robots can be used monitor different parameters related to the use of such gases in an apparatus or gas filled chamber. In this tutorial, a wireless robot is designed which can move inside a chamber or well and detect the level of concentration of the gas at the spot.

Controlling a BLDC Motor with an ESC
Brushless motors have much more satisfying results as compared to brushed motors. The basic difference between them is that in a brushless motor, the rotor itself contains the permanent magnets and the electromagnets move to the stator which is quite opposite as seen in a brushed motors. It’s more precise and can also factor the speed of the motor into the equation. This makes brushless motors more efficient. There is no sparking and much less electrical noise. There are no brushes to wear out. With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.
RFID Based Attendance System using 8051 Microcontroller
This project named “RFID BASED ATTENDANCE SYSTEM” is based on RFID as the name suggests. In this project our aim is to make a note of every employee entering the room and also to calculate the amount of time person resides in room. Before company used to enter the data in register and it was bit clumsy. Company then thought of going for barcode but barcode was not that much durable? Barcode requires continuous line of sight, low data capacity, cannot be rewritten etc. due to this problems barcode cannot be used. So RFID is the solution of all problems. It is quite easy to work with. Tags con be reconfigured if read/write tags are used. Range can be improved by using high frequency reader. It can also add to security. By programming many other facilities can be added.

How to use the ADXL345 accelerometer sensor
Inertial sensors are used to detect linear and rotational motion of an object. There are two types of inertial sensors – accelerometers that detect linear acceleration and gyroscopes that detect rotational motion. Accelerometers and gyros are widely used in several applications, including aerospace, military, automotive, mobile phones, and consumer electronics. For example, in mobile phones,…
Transformerless Power Supply
One of the major problems that is to be solved in an electronic circuit design is the production of low voltage DC power supply from AC to power the circuit. [[wysiwyg_imageupload::]]The conventional method is the use of a step-down transformer to reduce the 230 V AC to a desired level of low voltage AC. The most suitable and low cost method is the use of aVoltage Dropping Capacitor in series with the phase line. Selection of the Dropping capacitor and the circuit design requires some technical knowledge and practical experience to get the desired voltage and current.
Designing an Arduino-based EMG monitor
Electromyography (EMG) is a medical procedure that evaluates the health conditions of muscles and nerve cells. These cells transmit electrical signals that cause muscles to contract or relax. EMG is used to read these signals and plot them as numbers or graphs. Typically, EMG is performed by doctors as one part of a diagnostic tool…
Wireless distance measurement using ultrasonic sensor
The distance measurement project is very helpful project, which can be used in cars to avoid accidents, or in any distance monitoring systems in industry, and also can be used in liquid level indicators like fuel tanks in planes. This system consists of ultrasonic sensor with microcontroller and display. The sensor, display and circuit are connected with wires. So if it is required to place sensor and display at some distance (say 2-3 meter or more) then we have to make long wire connection. But in some systems it is required to monitor / measure distance from remote place. Like the sensor is connected in wireless robotic vehicle and we need to know the distance of any object around the vehicle at a remote place. In that case it is required to transmit the sensor output and display it on LCD at remote place. This is possible with the help of RF technology.

Designing an Arduino-based ECG monitor using an AD8232 ECG sensor
Cardiac disease is a concern as people age. In fact, heart problems are fairly common in men over the age of 50 but are increasingly affecting younger adults, regardless of gender. This is attributed, at least partially, to more sedentary and stressful lifestyles and unhealthy habits. But genetics may also play a role. Electrocardiogram (ECG)…
Controlling Appliances Wirelessly using RF Technology
Now a day’s everyone needs a device which could control appliances wirelessly. This makes us to operate them on our fingertips from particular vicinity with ease.This time I have done something like this, I have created a prototype of a device which controls 4 devices/appliances separately using RF (Radio Frequency) technology. The device comprises of two sections: Transmitting (remote) and Receiving part. The transmitting part works as a remote device to send the corresponding data to the receiver section. It further consists of 4 SPDT (single pole double throw) switch, one Encoder IC (HT12E) and a TX module (433 MHz). These 4 switches are connected to the 4 data pins of the encoder IC to generate a 4-bit data to be transmitted. The switches provide either high (+5V) or low (0V) signal levels.

Joystick Controlled Wireless Robot
In one of the previous projects “Hand Gesture Controlled Wireless Robot”, it was discussed how remote controls with switches or buttons used for controlling wireless robots have a disadvantage in controlling the robot due to response time factor of the human handling it. As a solution to the problem, use of advanced human-computer interfaces like the gesture recognition, eye movement tracking, and brain waves was suggested. Of which, hand gestures were used in the previous project to control the robot. In this tutorial, a wireless robot will be designed that will be controlled by the joystick. A joystick is not a new input device but it provides better control over the subject. It is easier to use and handle by a human operator.
