LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing rate can be adjusted using a potentiometer in place of 47K ...
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, ...
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 ...
This small application is a arduino implementation of a simple timer. It allows you to display a timer on a basic LED panel in combination with Blynk IOT. The timer can be simply setted over your ...
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 ...
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 ...
Purpose To evaluate blink rate effects by a novel light-emitting diode (LED) timer device (PISC) on non-dry eye (DE) subjects and DE patients during a reading task on liquid crystal display (LCD) ...
