wat if u buy the ultra sonic
wat if u buy the ultra sonic range finder (wich is realated to srf05). would it still be in the same instruction?
Please write better
Please write better english.
I do not know which ultra sonic range finder you are referring to, so I cannot tell. The SRF05 is a ultra sonic range finder.
hey…
dude i write like that all the time… you can probably tell. it’s because my pinkeys are way too lazy too reach over to the “shift” key. or maybe its just me.
did you ever get the part?
did you ever get the part?
the range finder that i
the range finder that i bought is the same as the one in the picture. and its very similar because the eyes are a little different and the circut board behind it is colored blue. plus theres only 3 connecter than the one in the picture on top. if u want to know wat it looks like heres the website. http://shop4.frys.com/searn?search_type=regular&sqxts=1&query_string=ultrasonic+range+finder&cat=0
o ok i get it now. thanks

Mounting SRF05
Hi all. Just started making 'my first robot'. This way of mounting the SRF05 works well. It's a 10way IDC header hot-melted to the servo wheel. The 4 required wires are crimped into the connector in the relevant places. It gives a solid base for the SRF05 and means you can easily take it off for use on another project. Just an idea....
PS - this is great little site with loads of great ideas. Thanks Frits !!!
thats actualy not that bad

And I only made a tiny part, so thanks goes to everyone else!
And thanks to you for sharing, now you made it as well. I think you should post this as a tip/walkthrough, and tag it SRF05.
See the front page, top left.

voltage difference.
The Picaxe 28 can handle voltages from 4.6 up to 6 volts according to the manual. In the SRF05 manual it states that it runs of 5 volts. Will the SRF05 fry if I connect it to a Picaxe running on 6 volts?
I would not know,
I would not know, sorry.
However; I have never fried any picaxe, and I sure have done all the wrong things with them; Hooked motors up, that generated power back etc.
The SRF05’s on the other hand; Each time I am just a little sloppy, I fry one! The fried ones can be used as models for drilling and fitting later, but still… What I am trying to say is that they are sensitive!
How about one of them resistors? Or something like it… ?
Don’t fry it!
I wouldn’t count on it! They seem to be fairly fragile and the datasheet says 5V so I would stick to that if you can. You could try:
a) If you’re using 4x 1.5V batteries you could ‘tap off’ from the third giving 4.5V for the SRF05 but use all four for the other bits in your circuit. I’ve run mine off 4.5V with no problems.
b) You could also use 2 diodes in series to drop the voltage connected to your SRF005. Each diode will drop it by about 0.6V so if you had 2 in series it would drop to about 4.8V but this is a bit inefficient.
c) Using a ‘low dropout’ voltage regulator. I can’t think of one of hand but they are available. A 7805 will not work.
If it were me, I would tap off the 3 batteries - it’s simple, will work and won’t cost you anything.
Yer, me too, tapping off 3
Yer, me too, tapping off 3 cells. Very nice, very low tech, I like.
Picaxe is 4.5v or 5V, not 6V
From the Picaxe Manual:
Power Supply:
4.5V or 5V DC is recommended. Do not use 6V, 7.2V or 9V battery packs, these could permanently damage the chip.
Two SRF05
Hi,
Could you teach me how to connect an second SRF05 to the board?
Just do the same with
Just do the same with everything… but chose other ports (connections / pins on the board), other variables (b0, b1, wo, w1 etc) in the code.
Headers+jumpers
Hi, I’m new here
Do I need to solder header pins to the sensor since there is no pins available (unlike the Ping ultrasonic range finder) and then is it possible to connect them with four female-female jumper wires to the board? I’ll follow the illustration above but wanted to make sure how to physically connect the sensor to the Picaxe ouputs and the choice of connectors. It may seem obvious to you but I’ve actually never seen the components yet but in pictures, I just want to avoid too much soldering.
By the way, thanks for your tutorials, they are very helpful.
THere is not one right
THere is not one right answer to how to connect stuff.
You can get all sorts of pre-made wires and pins to make snappy connections… and you can also just solder everything on.
You have to try something, learn, find your favorite ways & tools.
