The String functions charAt() and setCharAt() are used to get or set the value of a character at a given position in a String. At their simplest, these functions help you search and replace a given character. For example, the following replaces the colon in a given String with an equals sign: String reportString = […]

The blimp is controlled by a transmitter on the ground, operated by a human. There are three control levers– one for each motor, and one for the servo that rotates the axis they’re attached to. You push / pull to make the motors speed up or slow down; they’re controlled individually, it’s like driving a […]

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 […]

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 […]

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 […]

On this instructable I will try to show how to interface a RFID sensor with the Arduino. I am using the RFID sensor from seeedstudio the serial version of it. There are a few parts you will gonna need. I also bought some RFID keys. UPDATE: Now it works with IDE 021 Step 2: Plugging […]

I’ve always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I’ve been playing with the Arduino Microcontroller, and […]
