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...]

Previously, we discussed about ESP8266. Working With ESP8266 Not Exactly Just Easy. Here is Circuit Diagram, Code to Setup Arduino WiFi Control of LED From Web Browser to Help New Users. We searched the whole web as much possible to find easiest tutorial which a newbie can follow. Basically, ESP8266 as one component involves complex networking matters. There are development boards for IoT, which … [Read more...]
