My apologies for the shortage of posts this month due to shortage of writing time while I've been focusing on other projects.
Speaking of projects, at the last Cumbria Group meeting we were updated on two very interesting developments. Firstly Mark Bradley has made great progress on his operator messaging project which was featured in September 12
A timetable of train movements has been created initially on a card system so that operators were aware of which trains to expect or prepare for the next sequence.
The movements are now recorded on a memory card and each record is sent by the Arduino Mega via it's I2C bus to the relevant display or displays.
Different display types have been tested and the records can be advanced or reversed in single steps or in tens.
The code is available from Mark for those interested.
A second project this time from Tony Hoath, featured a complex scissor crossing with route switching using Arduino controlled relays to ensure the relevant polarity of the frogs.
As this was a coffee and chat meeting it was unfortunately not recorded.
I will try and get information on the circuit and code used in a later post.
