We Can Use Transistor To Have Some Loudness. How To Make a Piezo Buzzer Louder is a Commonly Asked Question By Whoever Use Arduino. We talked about transistor in our old post listing common transistors. But that is not all the answer. The Piezo Buzzer itself not any standardized hardware - you need to find buzzer which is itself loud.   How To Make a Piezo Buzzer Louder With … [Read more...]

The intention is to buy few of them to keep DIY stock supply handy. Integrated Circuit (IC) and Microcontroller, Programmable Microcontroller has difference, although they look similar and may be they are also "IC" in some way. IC weawre going to discuss usually nothing but just a circuit with basic electronic components inside in miniature form. Microcontrollers are usually more costly and … [Read more...]

First, we made IR Obstacle Detection Sensor For Dimming LED (Stop Event Facing Obstacle), then we made 2 Push Button One LED to Switch On/Off project. Here is Circuit Diagram and Code To Make LED Switch On By Push Button Switch Off By IR Obstacle Sensor and Arduino Board. In next guide, we will improve our Arduino Door Bell - door bell will start with glowing LEDs upon button press and stop when … [Read more...]

Transistor is kind of scary to many beginners as most commonly, transistors are not given importance than vacuum tubes within twelfth grade course. Here is Kind of List of Common PNP, NPN Transistors For Arduino, Raspberry Pi Projects for the Beginners. Also, in this article, we will discuss basics around transistors. Transistor can be used as a switch or an amplifier. Our guide to use buzzer with … [Read more...]

The thing sounds like childish. It is True That is Very Easy Yet It is Important Basic Behind Using Sensors to Switch On/Off an Event. Here is Circuit Diagram and Code For Arduino 2 Push Button One LED to Switch On/Off Project. In our older how to guide, we have shown IR Sensor to switch off LED. As upgrade of the project, we can use that IR Sensor to switch off LED instead of pushing it with … [Read more...]

Normally, We Use IR Obstacle Sensor to Initialize an Event, Like Lighting Up LED. That is commonly what we need for robotics. Like in our previous guide, Arduino IR Obstacle Sensor Buzzer With LED, we started LED and buzzer when an obstrucle was in front. But We Can Do the Opposite. That stop action makes a digital switch working like our regular switches - when you are present in front of a desk … [Read more...]

Normally For Arduino We use Regular IR Distance Sensor. There are reasons why we need to publish a separate article comparing Regular IR Distance Sensor Vs Sharp IR Distance Sensor. It is basically meaningless to buy Regular IR Distance Sensor unless there is reason. Because Ultrasonic Distance Sensor is quite closer in function and cost. Regular IR Distance Sensor is cheap and great to use as … [Read more...]

When an opaque material will come closer to the sensor, the buzzer will make sound LED will light up. Here is a Complete Guide to Setup Arduino Regular IR Obstacle Sensor Buzzer With LED With Schematic, Code, Illustration and Video. Upon searching the web, I I found that there is no proper complete guide of this basic thing. In this guide, we will use Regular IR Obstacle Sensor, which cheap; not … [Read more...]

Mechanical counters look beautiful and even 2 decades back they were common to find in cars, two whellers, gas stations, electric meters, video tape players an so on. Some had mechanical reset to set to zero, some were cumulative. Here is Basic Information Around Mechanical Counter for Arduino as They are Difficult to Find Outside Industrial Usage. They Can Be Stepper Motor Counter With or Without … [Read more...]
