In a previous guide we talked about ordinary switches which we use in electronics and household work. DIP switch is not what we normally see among the consumer grade products but it is cheap and very useful tool. Here is an illustrated guide on how to use DIP switch on breadboard for the newbies with explanation of types of DIP switch & easy examples. Before using anything new, we need to know … [Read more...]

Detailed article on computer hardware parts like RAM, Motherboard, Processor, Graphics card. Hardware also covers topics on hardware of Server, Single Board Computers like Raspberry Pi to Libre Hardware Projects.
Arduino Sound Meter With LED : Easy But Better
Some wrongly refer these as VU meters. VU Meter is too much but these are entertaining. Volume Unit meter (VU meter) device display representation of the signal level in audio equipment, which has some of standards. We are just building a "sound meter". You need some LEDs, couple of resistors, ceramic capacitor to build this Arduino Sound Meter. Frankly there are more easy guides with almost … [Read more...]
Arduino Wireless Electricity Transmission Project
Definitely you heard or saw or using some from of wireless electricity transmission. We have a basic technical article on wireless charging. This guide, Arduino wireless electricity transmission is a complete DIY, easy project with basic electronic components with circuit diagram and code. We talked about different types of copper wire, the needed wire is called winding wire. We will create need … [Read more...]
ATtiny Arduino Boards For Cost Saving Projects
It is probably normal or expected that many of the Arduino users will know very less about the microcontrollers. Genuine Arduino boards are for development purpose, but one need to search for low cost for really creating a project which will be used. The methods of cost reduction varies and depends on the skill of the readers. Ready to use cheap ATtiny Arduino boards available which can be used by … [Read more...]
DC Motor Speed Controller (PWM) Buying Guide
These days cheap China PCB circuits with knobs are sold as LED Dimmer, Voltage Regulator, Motor Speed Controller. Here is DC Motor Speed Controller (PWM) buying guide for understanding. If you do not understand what is PWM - that is Pulse-width Modulation, you need to watch our Arduino guide for DC motor control which has a video. In that video, we had way to input 0 to 255 values to control the … [Read more...]
DIY Benchtop Power Supply (ATX) : List of Needed Components
In previous articles we introduced to practical work on how we can use DIY benchtop power supply, we talked about various types switches and various types of fuses used in electrical and electronics. Our target is to help the newbie who are not used with electrical, electronics, have less budget but want to learn electronics works. I talked about what is -5V like negative voltage. Those previous … [Read more...]
What is Negative DC Voltage, Like -5 Volt?
Few weeks ago, we were discussing about building ATX DIY bench power supply - in that way, we can use or convert Computer Power Supply to breadboard power supply with stable, regulated voltage. Before explanation, for that DIY work - as computer's power supply is a ready to use solution for computer board, that negative DC Voltage, like -5 Volt are present. You will use only the positive DC … [Read more...]
Arduino DC Motor Control With Speed On TM1637 LED Display
This is kind of under development project. It only demonstrates that we can echo the serial input to display device. Here is Arduino DC Motor Control with speed on TM1637 LED display with basic easy circuit. Basically if we run TM1637 LED Display, Arduino and DC Motor simultaneously drawing power from computer's USB, performance becomes unreliable! More funnily, the basic circuit is of our Arduino … [Read more...]
How to Solder Electronic Components : Through-Hole
Ordinary soldering irons are not costly and you can try. Soldering is one of the most needed skill in the world of electronics. Alternative to soldering in part is wire wrapping, but wire wrapping not always easy or perfect solution with currently available tools. Soldering through-hole technology components (through-hole components are commonly used by the makers and differs from SMD components). … [Read more...]
Types of Copper Wires Used in DIY, Household Works
It is common to face guides and tutorials DIY electronics works and household repair like we talked about solid core copper wire in another guide. Here is a brief, easy description with illustration of types of copper wires used in DIY, household works. We will mention the common gauges too so that you face less trouble in real. Copper wire are sold different varieties, and the differences may be … [Read more...]
Arduino Hidden Voltmeter & Thermometer
It is fun to know that Arduino boards has voltmeter & thermometer but that knowledge has not much use. Arduino hidden voltmeter & thermometer are features of AVR chips for the chips themselves. Not all Arduino AVR chips will have the thermometer. With hardware and software updates, old codes to demonstrate may not work at all. The thermometer has entry on official Arduino website with list … [Read more...]
