The Digital Clutch Slipper

The digital clutch slipper is an idea I had when I was driving a drag car with a very aggressive and harsh engaging clutch. I wanted a way to be able to slip the clutch the exact same amount every single time. Conceptually, the idea is simple. I need to add a way to either slow down or stop the movement of the clutch fluid in a controlled matter. I decided to do this using a hydraulic solenoid controlled by an Arduino, and the arduino is controlled via an iOS app.

The iOS app is able to connect to the Arduino using BlueTooth Low Energy technology. Once connected, the user is able to input an "Initial Delay" value. This delay is the delay that the Arduino will wait before activating the solenoid. In other words, the Initial Delay value determines the clutch position when the user steps off the clutch. Secondly, there is a "Clutch Hold" value. This clutch hold value is the amount of time the user wants the clutch to slip for. After the sequence is complete, the clutch engages fully and stops slipping.
