hallo there, i'm totally new to the arduino environment, and I need advice on a piece which i want to incorporate the arduino. I am going to work with solenoids and after reading whatever i can find about solenoids, i'm ready to take up the challenage. I will be getting parts as in http://www.arduino.cc/playground/uploads/Learning/solenoid_driver.pdf . I would like to work with a maximal of 16 solenoids and i am using a ATmega 8 board. I see 0-13 /14 digital ports. Can i hook up all 16 solenoids to this board? Is there other ways of doing this?
Basically i want a solenoid to be attach to a 140 cm long shaft to strike at the end. I know that this is rather long and i need advice on the impact the solenoide needs. What i choose is a 12v at 1.5W with power of 3N. Is this strong enough?
