Done modding the Parking brake Valve!

The original Scania Handbrake uses "AIR" instead of CAN-BUS or electricity. I needed it to modify to an electric part (push button) so I can connect it to an Atmel Enabled Arduino like "Pro Micro" or "Leonardo".

So right now the Valve has become a simple Push-Button which I can connect to an Arduino Pro Micro or Leonardo. The Atmel enabled boards will act like an extra keyboard to your PC so most parts in my simulator will act like a button of a keyboard keeping it nice and simple.

The Arduino IDE code Keyboard.print("b") will make your board send a letter "b" to your PC just like a press on the letter "b" of your keyboard. Boards like the "Pro Micro" can have as mush as 9 push-buttons connected. A "Pro Micro" clone (works fine) can be bought online for as little as $5.

The letter "b" corresponds to the ETS2 in-game parking brake toggle but can also be set different if you like.

Please have a look at my other LOGS for Arduino Code, Wiring Diagrams and other useful instructions.

How to:

1# Buy a Parking brake here or here

2# Buy an Arduino Pro Micro here

3# Buy a push-button here

4# Open the lit of the Parking Brake and remove all the lose parts like the spring

5# Place the push-button into the lit (where the plastic air-hose was connected)

6# Replace the 15mm copper bolt for a 30mm M5 bolt with rather large head

7# Temporary put back the lit with pus-button installed and adjust the new M5 bolt (trial and error) till it touches the push button (use multimeter)

8# Download my code and upload it to your board with the Arduino IDE software

9# Have fun and leave a comment and/or SKULL if you like my project
