In this write-up, I’ll show how to create a value in Processing and then send this value over the serial port to the Arduino. In the example I’m setting values of LEDs making them brighter o... Read more
If you want to RESET Arduino from the beginning without manually pressing the RESET button, there are a few ways. Here are two ways, using minimal wiring / circuitry. Step 1: Using 1 wire co... Read more
Overview A software / hardware combo that allows for control of the analog filter inside a Commodore 64 that is running Cynthcart from a host computer (eg, Macbok, PC). Software • 16-step fi... Read more
Overview The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz... Read more
Tired of having to find the dog food to feed the dog? Tired of having to get up early so your dog doesn’t attack you for his food? Are just plain lazy? If you answered yes to any of th... Read more
Quit pulling your hair out over incorrect passwords. Using an Arduino Leonardo and Adafruit’s NFC shield, you can unlock your computer with an NFC card. The Arduino reads the NFC card... Read more
Connecting the Switch To connect the switch to the Arduino, you will need the switch, two jumper wires, and a 10kΩ (brown-black-orange) resistor. Once you have all the required parts, you wi... Read more
I started recently to get interested in building Arduino based robots. Since it is a traumatizing process to take any creation apart, I am opting to keep mine alive and kicking. To lower the... Read more
This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone bo... Read more
This tutorial introduces programming for AVR microcontrollers. It uses the ATmega328p found on Arduino boards, but works with straight AVR C and a bare microcontroller. It covers the basic i... Read more
This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are conveni... Read more
My sensors have not been functioning too well with my computer, as every time I try to connect the hello.light or hello.mic boards and run python through my terminal, I either get the error... Read more
