I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long. I built it for use in a school that wants to provide visual feedback to students when they are being too loud. The “alarm” is a string of

This variation on the For Loop example shows how to use an array. An array is a variable with multiple parts. If you think of a variable as a cup that holds values, you might think of an array as an ice cube tray. It’s like a series of linked cups, all of which can hold the same

The if() statement is the most basic of all programming control structures. It allows you to make something happen or not depending on whether a given condition is true or not. It looks like this: if (someCondition) { // do stuff if the condition is true } [Get Code] There is a common variation called if-else that looks like

Arduino needs no introduction; it is an easy-to-use yet powerful open source embedded system development platform that has gained huge amount of popularity in past few years, specially among hobbyists. The standard hardware consists of an 8-bit Atmel AVR processor with on-board headers providing access to its I/O pins. The processor is pre-programmed with a

Sometimes, one serial port just isn’t enough! When trying to communicate with multiple serial enabled devices, while also sending info back to the main serial window, a few extra RX/TX ports can be a welcomed thing. This example makes use of one of Arduino Mega’s 3 auxiliary serial ports, routing any incoming data read on

Here is my instructable on how to construct a pretty simple (for some!) short range infrared rangefinder/range sensor. Infrared rangefinders are very useful in a number of projects. The majority of these come from obstacle detection (in robots) or generally detecting distances! The one shown here is only a simple rangefinder and will only really

This is my second instructable. I just had a mood of making a digital watch. But wanted to make it a learning process. I already had a sanguino i could have easily used that Atmega644 chip. it would have been more than enough. But i wanted to try burning a Arduino bootloader and see if

My questions for the Make-to-Learn Youth Contest 🙂 What did you make? This goal of this project was to take commonly available electronic equipment and create an inexpensive, self-controlled vehicle. In simpler terms, this is an attempt at basic autonomy. It uses an arduino logic board coupled with a cheap remote control car along with

Hi, everyone, i would like to introduce how i remake my mosquito killer here. With this remaking, my mosquito killer become “Smart”, and really facilitate my life. I rented a room in very remote place to save my money, in the summer, the biggest trouble I come across, is the mosquito.These annoying mosquitoes always woke

I decided to build a simple photo-booth as a fun addition for events, this goes through the basic steps of how i went from a few pieces of wood to a fully functional booth. I have also included a photo of what the images look like! Step 1: Cutting Wood Square sheet of MDF, 600mm
