Amazing help so far guys! Before I fully ingest Ame's suggestions with writing some commands, we're building our first prototype with a single brolly, but we've hit a snag again... As soon as the servo is connected up to the external power source (5v) the servo moves without us sending any commands....

Hi Joan, Thanks once again for your reply, we wouldn't have got this far without your help servo is working fine and we understand the way is works, all is mechanically making sense, just got to sort the coding now !!! we tried copying and pasting the bash code and nothing happened, is there a more ...

Once again a massive help Joan! Undertand why it wasn't moving now! The only thing is, we feel like there's resistance when its hooked up to the pi, whereas when its not got any power, the servo can be turned by hand? Is this normal? Just wanting to check. Dad thinks the fact that it feels like it's...

Thanks for that; the above command worked a couple of times, then the servo appeared to jam? Edited to add: it seems to work once then not again, and I can feel resistance in the servo. Any idea where we're join wrong? we have the servo wires red 5v brown gnd yellow gpio23 i also notice that sometim...

Stuck on the software now :( I *think* i've installed servo blaster, and set it to load the kernel whenever the pi is booted. So then I open lxterminal... What exactly do I have to type?! Sudo Python? I'm so sorry I'm asking such stupid questions... this is so embarrassing haha! also we're using gpi...

Thanks for the reply. Downloaded ServoBlaster, I assume this is like PigPio? We're currently busy trying to attach the server to the gpio, then will attempt to run Servoblaster. Then we will try to put some code in to see if we have some sort of movement? I saw this code on another website: [root@al...

Hi, thanks for coming back to us,
the servo is a tower pro sg-5010
wires are brown/red/yellow ,
we do have a external power block that takes 4 x aa batteries.

I've connected the 100mm rainbow cable to the Pi and have just soldered the box header to the pcb
cheers
Tim and Katie

Hello again! So me and Katie are sitting with our just setup Raspberry Pi and servo. And looking blankly at each other! What is the first step from here? We have been reading about the pulse width modulation which we understand but don't know how to do. We've never used Linux before and we really ar...

Thanks for your detailed reply. The cocktail umbrellas are 12cm wide when open. If 16 is a reasonable limit, we could perhaps do it in clusters of 16 as the space where she'll be showing her work is quite airy and large, so just 16 on their own will be a bit dwarfed! She's going to concentrate on th...

Thanks for your reply, I can do standard household wiring and basic electrics but this is all new to me so I need to be starting at the beginning ! Regarding which hardware, this is where I need advice what servos and ones that will work with Pi, I'm more that capable of making linkage from servo to...

Hi All, never heard of Raspberry Pi until about an hour ago, an assistant in Maplin told me a bit, My daughter is in her last year at uni and is onto her final pieces, so I got one of those "can you help Dad" calls Katie wants to Automate approx 10-20 cocktail umbrellas just to open and close in a s...
