Thus spake Jean-Francois Joly (jolyal@CAPITALNET.COM): > But the PIC can supply enought power to send pulses to the pulse pin? > And then I can connect the power and ground pin to a battery or something? Yes, the servo can be run off the same 5V supply you use for the PIC. It needs 4.5V-6V as a rule. > Can the TS-51 be easly converted so it can fully rotate? (365 degrees) No standard servo can rotate more than 270 degrees, most are only set up to rotate a maximum of 180deg, and normally only about 90deg of this is used. The fundamental limit is that the feedback pot inside is coupled directly to the output shaft, and the pot has an carbon element with a maximum range of 270deg. You can get things called "sail winch" servos that will rotate multiple times. I don't know if they are directly compatible with standard servos for control. I assume they drive the feedback pot via a reduction gear. Clyde -- Clyde Smith-Stubbs | HI-TECH Software, | Voice: +61 7 3354 2411 clyde@htsoft.com | P.O.
