I’m a programmer/systems architect by education and by the way of winning bread, but somehow I got infected with the electronics bug 3 years ago – had a sidejob to upgrade the firmware of a LED display, got into microcontrollers, then made myself comfortable in analog. Dave Jones has been saying in his videos – […]

With LEDs that require only one pin, you can do a lot with even just a 6-pin microcontroller! A touch controlled light with 4xWS2812 RGB LEDs and ATtiny10. This is a small hardware project which utilizes the light_WS2812 library and the TinyTouchLib to implement a touch-button controlled RGB-LED light. Only two output pins of the
So this is a 4×4 projected capactive touch board using Atmega32u4 and back-fire LEDs for each button. I want to send the gerbers to Seeed sooon so any advice/feedback is very much appreciated. It fits SoB 100x80mm but the top acrylic will sit right on top of the PCB as the dielectric properties of whatever

I develop this MCP23017 Brekout 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 lines

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 SoftKinetic’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 CamBoard Pico S, a smaller version of their CamBoard Pico 3D depth camera that

The new iW3606 and iW3608 single-stage, solid state lighting (SSL) LED drivers from iWatt 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 of

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
