The project is a simple way of producing a fading LED without the need to program the chips or write the code but rather using a few simple components with a constant fade up and fade down as the end ...

Semtech has introduced an analogue timer chip that runs from 0.9V, but can drive LEDs at over 3V. Called SX8122, to the timer it adds: a simple battery charger, a boost converter, and a power-down ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...

We did explicitly ask for projects that use a 555 timer for the One Hertz Challenge, but we weren’t expecting the 555 to be the project. Yet, here we are, with [matt venn]’s Open Source 1Hz Blinky, ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...
