Hi all, I have a challenge I cant solve, I need your help!
I have a truck cruise control lever I want to connect to an Arduino Leonardo and have it act like a keyboard (HID).
The lever has only two wires so I need to stick with 2-wires. The lever has 3 push buttons and one toggle switch. I do know the input voltage is 5 volt and every button has its own resistor causing different voltages to come out when used. This way the car computer knows what has been pressed.
I have 3 switches:
1: Acc (Cruise Control Accelerate speed)
2: Ret (Cruise Control Retrieve speed)
3: Res (Cruise Control Resume from last speed)
I have one toggle Switch:
Cruisecontrol ON/OFF
I want the ON/OFF to toggle a keyboard character “C” when used.
I want button 1 to send a “7”
I want button 2 to send an “8”
I want button 3 to send a “9”
The code should pause after each change (no loop). The 10k Restistor is a pull-up resistor for debounce.
There is an Arduino Ohm meter tutorial so that might be a start.
Anyone?
PS:
Code unfinished:
// Arduino Leonardo Rev3.0
// This code is for all Scania 4-Series
// ACC HID control for ETS2
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int analogValue = analogRead(A0);
// print out the value you read:
Serial.println(analogValue);
delay(100); // delay in between reads for stability
if (analogValue > 870 && analogValue < 890) // read the analogue input into variable analogValue
{
//ACC is in the OFF Pos
Serial.print(“ACC OFF”);
delay(1);
}
