- This video will describe how to make an Angular Rotation sensor using an automotive sensor (TPS). The sensor output is fed into an ADC of a Scamp3 board for decoding. Simple code written in Flashforth will be shown.

Your alway coming up with great ideas
That's really brilliant, Ken. I've learnt something new. :) Great video.
Hi John, I actually used these in a design of an industrial machine. Simple but very effective. I just came from your web site and I see you have done a major update ... looks good.
"Saving the world from Arduinos since 2017" ha ha, good one.
Nice! I'm a bit confused by the 2600 value and the > check. Firstly, wouldn't the alarm be a less than < check since the offset would be close to ground, ground being zero? Also, the Scamp-3 has a 12 bit A/D and 2600 is roughly 57% of the 4096 scale so I would have thought the value would me much lower and not close to mid range. Thanks!
Total shaft rotation will give values from 205 to 4095. Run "test" and turn the shaft to the alarm angle and read the value, 2600 in this case. Any value greater than 2600 will alarm, and turn on the LED.
@@0033mer Wow, so nearly half the range is in alarm, that cuts resolution by more than 1/2!
Every LED has a value of 256 so you can make your alarm threshold any value you want. This is just a demo.
Nice inexpensive way to use a potentiometer already packaged than trying to hack something together or design a case on a 3D printer.
Hi, at 3:34 you said "so the computer knows how far you are pressing down on the gas pedal for the fuel injection system". I'm not much of a car guy, but I don't think engines with carburetors have fuel injection. That said, this is a GREAT video and gave me a lot of ideas of where I could use something like thing. THANKS!!!!
After thought: You said "Fuel injection system", not "fuel injector", so I retract my above comment, a carburetor could be part of a fuel injection "system" for an engine if we consider normally aspirated a "fuel injection system". Like I said, I'm not a car guy. So I have no credibility in this area.
The device is not a carburetor but rather a "throttle body" which only controls the amount of air entering the system, while the injectors apply the fuel. This throttle body is also "drive by wire" ruclips.net/video/h1aA5gfeU34/видео.html
@@0033mer even better, now I learned a few things. Been looking over some of the other videos, all good stuff. thanks
Beautifully explained as always
Thanks a lot 😊
