−Inhaltsverzeichnis Thermometer width DS18S20 Hardware Software final Download Thermometer width DS18S20 In my new Dacia Duster is missing unfortunately an outside temperature indication. A finished thermometer with LCD did not separate from there while the contrast with sunlight usually particularly is. I had still alphanumeric LED display in red there for this project in the …
I develop this MCP23017 Breakout Board to interface a 2×16 LCD display with any microcontroller using a standard I2C bus. Typical 2×16 displays needs at least 6 lines to work (when working in 4-byte mode); in some cases, this will be prohibited for some microcontrollers. With this board, you can control it with only two …
Write messages and show animations on this palm-sized heart-shaped LED display. Works seamlessly with Arduino, and requires only three pins to control. Want a heart matrix of your very own? You can buy this DIY kit for $17.95 on the product page. How does it work? Three shift registers control two LED matrices, each with …

With the proliferation of high-brightness LEDs designed to provide replacement lamps for commercial and domestic lighting there comes an equal, if not greater, proliferation of power supply solutions. With hundreds of products from dozens of manufacturers, it becomes a question of how to make sense of all the permutations of input / output voltages and …

After checking out Soft Kinetic’s embedded 3D depth camera earlier this week, our attention was brought to a similar offering coming from Germany’s PMD Technologies and Infineon. In fact, we were lucky enough to be the first publication to check out their Cam Board Pico S, a smaller version of their Cam Board Pico 3D …
The new iW3606 and iW3608 single-stage, solid state lighting (SSL) LED drivers from I Watt feature a wide, flicker-free dimming range from 100% all the way down to 1% of measured light, to closely match the dimming performance of incandescent bulbs. This enables the smooth, “natural” dimming, with no light drop-out at the low end …

A versatile kit that can be configured to drive either constant voltage LED arrays or constant current LEDs. Use the kit to dim under-cabinet LED lighting using flexible LED strips or build your own LED desk lamp using High Brightness LEDs. The majority of the circuit is identical for both types of LEDs. Two inexpensive …
LED matrix displays provide flexibility to display text, graphics, animations, and video, and therefore, they have become a popular mean of displaying information these days. You can see them at gas stations displaying the gas prices, or in the public places displaying information, and alongside highways displaying advertisements on large dot matrix panels. This project …

You can use an LED as a photoelectric sensor. A previous Design Idea shows that such a switch is highly power-efficient, consuming almost no power (Reference 1). However, you cannot adjust that configuration to switch at the desired light intensity. You can adjust the circuit in this Design Idea to any threshold level of light …

Plymouth, England – 8th April 2013 – Plessey announced that samples of its Gallium Nitride (GaN) on silicon LED products (p/n PLW111010) are available today. These entry level products are the first LEDs manufactured on 6-inch GaN on silicon substrates to be commercially available anywhere in the world. Plessey is using its proprietary large diameter …
