This ambient LED light designed by Jasper Hou is powered by a mechanical timer in the base. After giving the base a twist, the timer gradually releases its energy, powering the LED light as it unwinds ...

This is a simple project to build a small timer using a 8x8 LED matrix driven by a ATTiny85 microcontroller. Each LED is a minute but I'm still searching for an original way to display the time. The ...

This 5-color LED flasher circuit can be built using the popular 555 timer and 4017 decade counter ICs. It does not require any expensive components like a microcontroller. The timer IC is used as an ...

For this mode the timer prescaler is set to 8000-1 to generate a clock signal at 10KHZ. The auto reload counter register value is set to 10,000-1 so that we can generate a LED blink every 1 second.

Looking for something with a bit more style than the traditional kitchen timer, [Martin Jonasson] decided to take the last couple of months to design and build his own take on the idea using a rotary ...

In our previous Nuvoton Microcontroller tutorials, we used a basic LED blinking program as a getting started guide and also interfaced GPIO as an input to connect a tactile switch. With that tutorial, ...

This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...
