Thank you Edmunds. Help how do I DM you? Lol I too have been working on the 1:87 & 1:76 oxfords scale cars and trucks for a long time, happy to share all the bits I have found so we can compare notes would be goid to get somthing 100% working without using remote controle.

Pic axe 14M2 hall effect OH49E. Working voltage 5 volts motor connected to picaxe through 1 x 2n7000 mosfet. It is hoped the picaxe will also be able to operate as an ir reciever to flash some leds and operate a relay to reverse the motor. I belive this may be too much and will have to be...

Here is what I have so far cobbled together from other peoples examples. It is basicaly the pot control of motor speed code but replacing the potis the hall sensor. The idea is to slow and stop the motor as the magnet approches over a distance of 10 mm

Thank you i'll post what i have but its not much at the moment. The main problem is usualy I would place the sensor between pos and ref resistor to neg to get the result but I am using a hall sensor so the output is pos and goes neg as a magnet aproches. I'll post the values also. Thank you for...

Good day Edmonds I to am working on some 1:87 scale controls may be we could get our heads together. Great with the line follower I to thought of using UV ink and adding dots and dashes into a separate line to tel the vehicle to put indicators on slow down speed up etc.i managed to get the photo...

Hi can any one help I am trying to make a distance sensor using a hall effect sensor. What I want to end up with is a sensor that can detect a magnetic field and slow a motor using pwm as it approaches the field. The problem is the sensor only gives an increasing posative number as it approaches...
