CMOS oscillator (D.U.T.) : various topologies of Schmitt-Trigger based squarewave oscillators

I tried if it is possible to use one of the PWM pins of the Arduino to dim the LEDs if I want to. Short answer: yes and no.

My first finished wordclock. It is using a DCF77-receiver to get the current time and an Arduino to interpret it and light the LEDs.

Project page: https://projects.schneidr.de/wordclock/

It is powered by a simple USB power supply. In this video it is running a simple program that simulates the time by counting the seconds up. The time is iterated by about 1 minute every second.

While I was working on my wordclock I must have accidently shorted out some contacts ... the wordclock suddenly went nuts 😃

First test to access the accelerometer of my Android mobile phone. I intend to use the phone to remote control my R/C boat when it runs on an Arduino.

I really needed some magnets. Sadly the clay wasn't the right one.
