This project describes an Arduino-based FM transmission using the KT0803K Digital Stereo FM Transmitter Radio-Station-on-a-Chip. The KT0803K device is designed to process high fidelity stereo audio signal and transmit modulated FM signal over a short range. It features an on-board 20-bit audio ADC and supports standard I2C interface for frequency setting and power control the …
The BareDuino Nano is the world’s smallest Arduino compatible board. It was designed by a very young maker, Niek Blankers, aged 15, from the Netherlands. Niek has been interested in electronics since he was less than 8 years old. A couple of years ago when he was given the first Arduino board, he fell in …
To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope. Circuit diagram Here is the scheme, I am using the typical instrumental amplifier(ins amp) and then another op amp to get some more gain. An ins-amp is like an …
Push the knobs The knobs all have convenient actions if you push them: pushing Vertical Position or Horizontal Position centers the trace vertically or horizontally. Pushing Tigger Level sets it to zero. Pushing Scale sets it to fine adjust mode. Long Memory If you don’t use Long Memory, you’re wasting most of the capacity of …

The Arduino library has always had an “analog Write()” function, even though the AT mega doesn’t have any way to generate a varying voltage. So why the name? Well, what most microcontrollers can do is generate a pulse-width modulated signal, also known as PWM. That’s just a fancy way of saying that the microcontroller periodically …
UPDATE: Please note that there no relation between my app and the one with the same name that popped up on Google Play July 3. As for the name ANDRUINO there’s a good chance I might change it to avoid any confusion. – July 7, 2013: I have completed a comprehensive round of testing and …

Pong was the first ever videogame that reached the mass market. For the first time in history, the concept of a “video game” was brought into the family home, thanks to the Atari 2600 – so it’s only right that we pay a little homage to this historical gem. Now, you can re-live that (admittedly …

If you follow our Pyro Electro articles, then you likely read about our construction and review of Club Jameco’s 8x8x8 LED Cube kit. Well we’re at it again, taking a look through a different kit, the Arduino Waveform Generator Shield. This shield provides an all-in-one DIY style function generator for low frequencies and the best …
The Dig stump/Dig spark team is back, bringing the experience gained producing over 40,000 and shipping over 25,000 Dig sparks in less than two months! Announcing the DigiX – the ultimate sequel project to the Dig spark. The DigiX has a 32-bit 84 MHz MCU, embedded low power Wi-Fi (b/g/n) and mesh networking, 99 usable …

A light meter is a device that measures the intensity of light. It finds applications in schools, hospitals, production areas, passageways and more to measure and maintain proper lighting levels. It is often used by photographers to determine the proper exposure for a photograph. Today we are going to build a simple light meter using …
