In this part of our practical electronics tutorial we will learn about diodes. Like resistors and capacitors they are also very common. They are simple component with two terminals. But unlike resistors they are polarized. That means two of its lead are not equivalent and cannot be swapped. Before moving any forward let us see how they look. Fig. Few Common Diodes Read more about diodes
Capacitors are two terminal electronic component used to store energy in form of electrostatic field. They are one of the most commonly used components. Among the many uses, some are :- Providing a bypass path for noise Smoothing voltage of power supply Blocking DC current (allowing only AC current to flow) Read more about capacitors.
Microcontrollers are good when it comes to brain, but to do anything in real world they need muscles too ! Their muscles are electromechanical actuators like motors. Their are several types of motor available to do various type of motion. The simplest of them are DC motors. They can generate rotary motion and when wheels are attached to their shaft they can be used to move a body. Applications include motion of a robot on flat surface like a floor. Normally a DC motors runs at a high RPM, so to slow it down a gear head is attached in front of it. This makes RPM come down to values such as 50 RPM to 500 RPM. This also increase the torque online casino no deposit generated by the motor. The image below shows a 12v DC Gear Motor. The front black portion contains the gear assembly. Fig. A DC Gear Motor In this tutorial we will learn the basics about these motors and how to control them using a microcontroller. DC Motor Rotates in one direction when you apply power to its terminals. When you reverse the polarity of the supply it will rotate in opposite direction. Since a DC Motor requires current in the range of 400ma to 1000ma we cannot supply them directly from the MCUs I/O […]
Recently I got the opportunity to work with an evaluation kit from element14. They bring development and evaluation kit for latest microcontroller, sensor and other electronic solutions introduced by several top notch companies. And user like me get the chance to get introduced with latest in technologies. And what is real worth telling is that these kits are really low cost ! For example Freescale recently introduced several MEMs sensors to measure parameters such as Altitude. Atmospheric pressure. Magnetic field (to find orientation, like a compass) Accelerometers. All these are recently launched and thus were ultra modern with very small size and consumed minimal amount power. The xtrinsic sensor board from free scale has all these sensors on one small PCB. Fig. xtrinsic sensor board Xtrinsic MPL3115A2 Pressure Sensor – For sensing atmospheric pressure and altitude data. Altitude data can me measured with an accuracy of 30cm.

As the journey enters its 16th year, Techniche – the annual techno-management festival of IIT Guwahati is set to write new chapters as they introduce the Model United Nations Conference as one of the highlights of the fest organized in collaboration with UN Information Centre for India and Bhutan. The MUN Conference is a perfect imbiber of all that Techniche seeks to achieve – to ideate innovation, nurture leadership and kindle global insight and aims at promoting the MUN culture in North-East India. Model UN conferences are a simulation of UN conferences and committees. Students take on the roles of diplomats from different countries, representing their nation in discussions and debate on a particular agenda topic in the conference. These agendas reflect issues taken up by the UN for discussion. Delegates must research their allotted countries in great detail, understanding their own foreign policy and thus the considerations and compulsions that determine state behaviour on the international stage. They must also research their committee agenda, fully exploring the intricacies of the issue at hand, including the background, history, its treatment in the UN system, resolutions passed on it, major countries involved, causes, consequences, past action and more. Finally, delegates must research and propose innovative and feasible solutions to the problem, within the framework of the organ or agency they are […]
Resistors are one of the most basic electronic component. They opposes(or resists) the flow of electric current through them, that is why they are named resistors. This article introduce you to resistors describing how they look, how to measure their value, how to solder them and how to identify them in a schematic. Read more about resistors.
Microwave Controller’s User Interface Fig. Microwave Timer using AVR ATmega8 The user interface has the following parts. Output Device: A 16×2 alphanumeric LCD Module is used as the main output device. It can display numbers, alphabets and few symbols. It can show two line and each line can have 16 characters. The backlight enables the text to be visible even in dark. A buzzer beeps when the system receive input from the user and the input is successfully processed. For example if the user presses 10 MIN button to increment timer by 10 min and this is successfully carried out the buzzer beeps. But if the timer is already at the maximum setting (90 minutes) the operation could be carried out, so the buzzer does not beeps. This buzzer also beeps a few time when the food is ready (countdown is finished) Input Device: Input from user is received by a keypad which has seven push buttons. The details of button is given below. Button Function Microwave Selects Microwave mode. Grill Selects Grill mode. 10 MIN Increment timer by 10 minutes. MIN Increment timer by 1 minute. 10 SEC Increment timer by 1 sec. STOP/Clear If the microwave is in on condition, this button turns it off and pauses the timer count down. If you are setting the timer, […]
Over the years I have seen people just open up the mouth without thinking. This is more common in the young age group like those of students. Often this also miss leads others. Recently we posted and ad on Facebook for our low cost development board which was priced at Rs. 299. Some guy without thinking a minute, compared it with a even lower cost product from some other vendor. What my point is that those two products are NOT similar ! Their are HUGE differences ! So I thought I should make out those differences stand out. Power Supply Our Board Probots’ Board Has built in 12V to 5V regulator circuit built using 7805 IC. No regulator. Advantage You can power up the board using an adapter of any voltage output between 9v to 18v Using higher voltage adapter has the advantage that power from it can be used to driver higher voltage devices like relays or motors. You can power up using a 5v adapter only! If you need 12v supply to power relays or motors you need a separate adapter or battery. Power Switch Our Board Probots’ Board Has an on/off switch No on/off switch Advantage Easy power control. Frustration on long run. Prototyping Area Our Board Probots’ Board Has large prototyping area […]
