This video is from a meeting of the Kids and Technology Meetup group in Washington DC. The youth who show up to these free meetings are eager to learn advanced uses of computers. The presenters were John Dukovich and Hugo Estrada.
Projects
Arduino Button Mouse Control Code
Using the Mouse library, you can controls a computer’s onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses a five pushbuttons to move the onscreen cursor. Four of the buttons are directional (up, down, left, right) and one is for a left mouse click Cursor movement from the Arduino is always […]
Arduino String Character Functions Code
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 = […]
Arduino-Radio Controlled Hydrogen Blimp
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 […]
Arduino Switch (case) Statement, used with serial input
An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use switch to turn on one […]
Potentiometer or variable resistor control LED Code
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 […]
MultiSerial Mega using Arduino
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 […]
Arduino 7 segment Displays Digital Clock With Charlieplexing LEDs
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 […]
Autonomous Arduino Car
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 […]
Remake the Mosquito Killer using Arduino
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 […]
