Testing Electronic Components

Is there a way to actually cut short the process of testing electronic components and at the same time produce the accurate result? We all know the rule and importance of “Troubleshooting” in Electrical and Electronics Engineering. Most EE Components and Elements used in Electrical and Electronics Equipments and Devices are common in their functions and operations.

To be a good analyzer and troubleshooter, you must know the following basic techniques in Electrical and Electronics Troubleshooting. In this basic tutorial, we will use AVO Meter (Ampere-Voltage-Resistance Meter) or multimeter (Digital/Analog) to test the continuity or resistance of the following components.

Testing Electronic Components

In troubleshooting, we use different kinds of basic Electrical and Electronics Engineering Tools but the main and important tool is multimeter. Now we will check the above-mentioned components and devices with this tool one by one. if you don’t know how to use a multimeter, you can use this application on your phone.

How to use Multimeter in Hindi

It covers almost all functions of Multimeter.

How to Check Components by Multimeter is an application in which you can learn how to check electronics components. This app will teach you what is exactly multimeter basic working.This App is very fruitful to those who are learning Mobile repairing or taking mobile or smartphone Training and also those who are doing repairing works.

Whether you are an electronic hobbyist, hardware engineer, mobile technician, or doing laptop repairing work this app is very useful to you.

Using application

This application consists much information on how to test electronic components.Usually, electronic components have been tested using a multimeter.In this application, you will learn how to test diode, fuse, capacitor, resistor, transistor and also a relay.When you understand how to test this type of components you will gain a better understanding of electronic engineering.

Open source Snow Plow Robot

A snowplow is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes.Since we are not insensitive to solutions making life easier, we have considered the idea of creating and proposing something that could help us avoid the cold and fatigue of using the usual manual shovel and at the same time, we opted not to replicate something already available but a new fun and technologic device. We, therefore, decided to start developing a Snowplow Robot, remotely controlled, proudly showing a robust mechanics and fine electronics all implemented with cards easily available on the market.
The result is a miniature version of a true snowplow, caterpillar tracks, with blade and light projector mounted on top to light the way in the dark; everything is controlled by a remote control from the PlayStation 2. Let us see how our caterpillar robot is assembled, starting from the mechanics and then describing the electronics and firmware that is necessary.

Initially it was thought to assemble the entire structure creating an aluminum tubular frame held together by corner brackets, but given the high mechanical stresses and the robustness required, we decided to use for the base four tubular iron (rectangular section) welded together, thus obtaining a rectangle by 600×375 mm. its good to use alumina on SnowPlow Robot.

like all robots, SnowPlow Robot need electronics board and control system. Electrical and electronic part of the snowplow is based on Arduino Uno, hosting three shields and interfacing with:

  • Motor driver.
  • relays circuitry RELAY1CH.
  • DC/DC converter step up STEPUP30V.
