Description The PS25401A is an ultra high impedance non-contact solid state electric potential sensor. It can be used to detect field disturbance due to the movement of a near-by object. This functionality can be employed in a range of applications including security motion sensors and non-contact electric switches for lighting, door opening, toys etc The […]

Hello, everyone !!! Today I’m going to show you how to make a thermometer with Arduino and LM35 termperature sensor, builded on a breadboard and conected together with jumpers (bunch of cables :D). Step 1: Gathering The Parts This is the list the parts needed to make the thermometer. If you dont have a 10k […]

This project was one of my final projects I did on my exchange studies in Finland. For this project I worked together with Fatbardh. This is a much larger and more advanced version of one of my first projects ever. Also a solar tracker: http://www.instructables.com/id/Arduino-Solar-Tracker/ . The features of this solar tracker are: Solar tracking: […]

Texas Instruments’ LM48901 is a quad Class D amplifier that utilizes Texas Instruments’ proprietary spatial sound processor to create an enhanced sound stage for portable multimedia devices. The Class D output stages feature Texas Instruments’ edge rate control (ERC) PWM architecture that significantly reduces RF emissions while preserving audio quality and efficiency. The LM48901’s flexible […]

The AD5686, a member of the nanoDAC+™ family is a low power, quad, 16-bit buffered voltage output DAC. The device includes a gain select pin giving a full-scale output of 0V to VREF (gain = 1) or 0V to 2VREF (gain = 2). The device operates from a single 2.7 V to 5.5 V supply, […]

The Chinese company Seeed Studio offers a lot of interesting things for electronics enthusiasts. Along with selling products from various manufacturers, Seeed develops and produces their own products, many of which are very innovative. For instance, a year ago we had a close look at the DSO Nano V3 miniature oscilloscope. Seeed has also developed […]

Description The DRV8837 provides an integrated motor-driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion-control applications. The device has one H-bridge driver, and can drive one dc motor or one winding of a stepper motor, as well as other devices like solenoids. The output driver block consists of N-channel power MOSFETs […]

As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart, […]

The goal of this project is to create a device that is capable of outputing VGA signals to a CRT monitor inorder to display figures, text and characters. Timing is a core essential in this project. If the signal is off by even 1 microsecond, the signal synchronization with the CRT display will be lost […]
