Train detection with a reed switch and a magnet

With a digital model railway, train detection (block signaling) is an important function. Most often current sensing is used. It is quite reliable and you don’t have any (possibly ugly and always non-prototypical) sensors in view. The drawback is that it probably also is the most expensive method.

TV Out with Arduino

This Instructable is for those who would like to use your Arduino to output to a TV. Granted the Arduino is only powerful enough to produce a black and white picture it can still be fun to play with and useful for some projects.

Two-trains-interaction with photosensors

Now that we can control 1 train with arduino, it’s time to add a second one. We made a track where the two trains share a part of the track, but also each have an individual part of the track. In this case we can let a train wait on his own track, while the other train uses the shared part of the track.

i2c Bus De i2c bus is een serieel bus systeem dat gebruik maakt van 2 signaallijnen, Clock en Data. Op deze bus sluit je meerdere slave devices aan en een bus master. De microcontroller is hier natuurlijk bus master. De bus master is de enige die mag communiceren met de slaves. De slaves versturen alleen data op verzoek van de master…..

Arduino Speedometer

The idea was to be familiar with the game and start KISS. So, before decide where to place in the Layout, I plan for a “portable” one ( so it can be used also on a modular layout during meetings ?)
