This is a simple test to read the distance using HC SR-04 ultrasonic sensor.

ISRKeypad

This is a test using Interrupt Subroutines to read a Keyboard.

motors

motorMOS-FET

This is a test to drive a motor using a MOS-FET transistor.

stepperMoveLib

This is a test to drive a stepper motor using Arduino Stepper lib.

stepperMove_PCF_8754_calibration

This is a test to drive a stepper motor using PCF_8754 expander.
