When you get time.this is a winter project.I have a PI I dont use.I plan to change the 555 timer,just to see what it will do.Awhile back you posted a 555 timer Tutorial,by Tom Van Room.if you bring it up on your computer,scroll down to where 10 timer prints come up.Fig-10. a better timer. question pot R1 and cap C.What would be a safe set of value to start with.Do you think 10K for R1 and 20uf are to low to start with.
