These projects are good for the beginners to learn basic things. We are showing a basic light meter, you'll try to add a push button to start and another push button to stop. In previous articles we have shown how to create basic sound meter with microphone and Arduino. That circuit was slightly difficult. LDR aka Photoresistors are more easy electronic component. Indeed, you can directly use a … [Read more...]

LED bar display is actually like multiple LED, it is not like Arduino modules like TM 1637. Here is a guide explaining the basics, circuit diagram, code on Arduino and LED Bar Display. We need no extra library for the LED bar display but we need correct circuit and logically correct code to use this electronic component. Big advantage of LED Bar Display is it is quite cheap, we can use with IC … [Read more...]

After Twelfth grade, in standard countries degrees really matters least for the intelligent and hard working persons in the field of applied science. Several times it has been proved that traditional education mostly good for nothing and humans with no traditional education became the best possible on the niche - Thomas Edison and Steve Jobs are two good examples. And in this era of information … [Read more...]

Normally we use breadboard for prototyping and various types of prototyping boards to make an Arduino project permanent. In such case, usually we do not use the Arduino development board but we use the components to build Arduino. However, not all project needs so much effort. For some, making only the non-Arduino part of circuit permanent works fine. In this Arduino UNO prototype shield tutorial … [Read more...]

Sorry to inform you - Arduino Programming Language really does not exit but newbies search for it. Our this guide on Arduino programming language tutorial explains where from that "language" originated. Also why we talk about writing codes in C++, C language. Please understand that .ino file, functions like digitalWrite() hides the real programming language. Most of us possibly need to use … [Read more...]

It is easy project but difference with other projects is several - after pushing the push button the sound automatically stops after a time (which happens with normal door bells), three LEDs used for rhythmic lighting with the music and very less number of components used. Only limitations are sound will not be very loud with buzzer and it is slightly difficult for the beginners to change the … [Read more...]

Made in China things are cheap but there are clones of Made in China things too. The situation become worser if the name of the components used is not known. There are different type of Arduino sound sensor modules available in the market with variable price and look. Here is a brief Arduino Sound Sensor Module buying guide. We do have guides with Arduino and microphone like Arduino clap switch or … [Read more...]

Clap switch is popular since our childhood in the days of '90s when basic electronic components were not so easily available and cost was not really towards cheap. Here is how to develop clap switch using Arduino Uno and microphone with circuit diagram, list of components and code. It is a basic project and also our second project with microphone. The previous project with microphone was a sound … [Read more...]
