Hi all! Here’s one of the last board I design the last year. On 2016, I develop the Dual USB Serial and I2C Converter board. Although this board works fine, it has a couple of lacks. First one, is that to use the both converters, you need two free USB ports. Is a minor problem

Monolithic Power Systems has introduced a new synchronous, 4-switch integrated buck-boost converter, the MP8862. The converter can regulate the output voltage from a wide input voltage range of 2.8V to 22V with high efficiency. The converter supports an Iout of 2A. Vout ranges from a 1V minimum to a maximum of 20.47V with a 5mV resolution
Being unable to expose myself to the sun due to a dermatological problem, I used the time I would have spent on the beach to build an ultraviolet rays meter. UltraV. It is built on an Arduino Nano rev3, with an UV sensor, a DC/DC converter to raise the 3v battery voltage, and a small

The FT232 USB-to-serial converter is one of the most commonly-used methods of adding USB functionality to small projects, but recently I found that these chips are capable of sending more than just serial signals. With some creative programming, individual output pins can be big-banged to emulate a clock, data, and chip select line to control

Hi guys, welcome to today’s tutorial. In this tutorial we will look at how to use the TCS230 color sensor with Arduino. To demonstrate the ability of the color sensor, we will build a color detector system capable of detecting the color in front of the sensor and displaying that color on a TFT Display.

Introduction Hi guys, continuing on our recent path of building really cool stuffs based on the Nokia 5110 LCD display, today we will be building a DIY Lux (or light) meter using the highly sensitive BH1750 light sensor. Illuminance (measured in LUX) is the total luminous flux incident on a surface, per unit area. It is a

Signal analysis: quick results See small signal details in the presence of large signals The R&S®RTM3000 features a customized Rohde & Schwarz designed 10-bit A/D converter that delivers a four-fold improvement over conventional 8-bit A/D converters. The increased resolution results in sharper waveforms with more signal details that would otherwise be missed. One example is
