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 ...

We can turn LED on and off at a rate of one second by configuring TRIGGER and TH0,TL0. Timer 0's 16-bit counting register starts counting at 0x(TH0)(TL0) up to 0xFFFF, at a rate of one count per ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

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 ...

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, ...

Read through the code and understand how the timer is configured and used to toggle an LED at a regular interval. Then modify the code to change the blink rate of the LED by adjusting the timer period ...

This circuit (Fig. 1) simulates the old hourglass timer. A total of 32 LEDs create the effect of sand grains passing from the upper half of sand-glass to its lower half. When the power is switched ‘on ...
