A reference design for an Arduino UNO compatible board based on the FTDI FT231X USB UART, delivers 5V at a full 1A without overheating. The UNO R3 is the staple of most Arduino based projects but it's been around for a number of years and many of the features have been improved for...

A complete IoT kit that includes all the hardware, software, and cloud infrastructure needed to quickly build a wireless IoT system. The Creator™ Ci40 IoT kit includes not only the hardware building blocks needed to quickly prototype a wireless IoT system from scratch but most...

Linear Technology Corporation announces the LT8714, an 80V input synchronous PWM four quadrant output DC/DC controller. This device cleanly transitions the output voltage through zero volts with up to 5A sourcing and sinking current capability, regardless of the output voltage...

Using the soil moisture sensor with an Arduino can't be easier. Adding a Nokia 5110 LCD display makes things more professional since we can visually check the moisture levels of the soil. The sensor can measure the levels of moisture in the soil. So it can be extremely useful if you...

The Galvanic Skin Response (GSR) is a property of the skin to exhibit electrical characteristics. It is also known as Electrodermal Activity (EDA), Electrodermal Response (EDR), Electrodermal Level (EDL), Skin Conductance Activity (SCA), Skin Conductance Response (SCR), and a lot...

Parker Dillmann @ macrofab.com has designed a wrist LED binary clock based on PIC16F527 Microchip mcu. The Macro Watch stemmed from those constraints. I picked the PIC16F527 microcontroller by Microchip to be the core of the watch because it was the cheapest MCU I could find that had...
