Detailed Description

Real Hardware Solenoid Control Test with ADC-Based Current Control.

This test demonstrates real-world solenoid control using actual hardware:

• Two solenoids: one single channel, one parallel pair
• ADC-based current control (0-3.3V maps to 0-100% current range)
• Independent min/max current limits per solenoid
• Real-time current adjustment based on ADC reading
• Proper parallel channel operation validation

Hardware Requirements:

• Two solenoids connected to TLE92466ED outputs
• ADC input (potentiometer or voltage source) on ESP32-C6 ADC pin
• Proper power supply for solenoids (VBAT)
