This project is for a motorcycles electronic steering dampener, called the HESD (Honda Electronic Steering Dampener).
The ECU controls the amount of dampening with a linear solenoid via voltage, depending on the acceleration and speed of the bike. 0VDC is no dampening, 5VDC is full dampening. The idea is to be able to switch between automatic ECU control and a manual override at the flip of a switch.
The ECU will fault out if the dampener is not in place, so we need a large resistor between 6-8 Ohm and at least 5W.
(5.75V x 0.85A = 4.88W) measured value
I've used a 6.8 Ohm 10W resistor with good luck, no ECU error-codes.
There may be a more elegant way of doing this, but this way its just simple.
So! We have a 12VDC source that needs to be cut down to 5VDC and be adjustable 0VDC to 5VDC. What would be the best way to do this? I'm not very savvy, so take it easy on me fellas
