Hi What do you think is the best way to test an Arduino sketch without uploading to the board? ie. What is the best piece of software available? I’m currently writing an Arduino sketch and it would be very usefull if I could test it without having to upload it to the actual Arduino board...

Show that the sum of (n/(3n+1))n from n=1 to ∞ converges. The book solves this with a comparison test to (1/3)n, but I'm making a mistake with an n-th term test somewhere. an = (n/(3n+1))n Take ln of both sides, then use n = 1/(1/n) to setup for l'Hopital's rule. ln an = ln(n/(3n+1)) /...
