Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier. Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a...

Max.K @ hackaday.io designed his own impressive watch based on Atmega328p with Arduino bootloader, Maxim DS3231 (<2min per year deviation),  96x96 pixel Sharp Memory LCD (LS013B4DN04) and it's powered by a CR2025 160mAh coin cell battery. Chronio is an Arduino-based 3D-printed...

Raj @ embedded-lab.com has revised his RGB Matrix Display Shield to an improved version. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2...

This application example shows how to connect and use RGBW LED stripe with TPS hardware platform. The main difficulty is that LEDs have their own color generation circuit inside. New FPGA Tibbit #57 can generate fast PWM signal, which is needed for proper LEDs operation. Also, the...

Last year, Arduino and Microsoft announced a strong partnership and Windows 10 became the world’s first Arduino certified operating system. This partnership made the creation and innovation much easier with the hardware capability of Arduino and the software capabilities of...

7 Seven segment multi-plexed display is tiny board that has been designed around Common Anode 4 digit Display, Display has 12 Pins. The board is provided with current limiting resistors on all LED segments and 4 PNP Transistors to drive 4 digits, the project is ideal for easy...

A radar system uses high frequency radio waves for object detection. A high-power RF pulse is transmitted into space and its echo reflected off from an obstacle is recorded. By computing the time elapsed between the transmitted and reflected pulses, and knowing that the electromagnetic...

Usually, when measuring a child's height at home, a mark is drawn on the wall then the height is measured using a measuring tape. This process is not always easy and it may has low resolution. In an attempt to simplify this procedure, a new project was developed using an Arduino and a...
