In this particular experiment, I use a button switch (digital input) to control the LED (digital output). Supposedly, when the button switch is pressed (HIGH) the LED will lights up (HIGH) and if button switch is not pressed (LOW) the LED will not lights up (LOW). As the switch button is pressed (HIGH), the LED will lights up (HIGH).   As the switch button is not pressed (LOW), the LED will not lights up (LOW). Conclusion In conclusion, the digital input can freely control

INTRODUCTION The galvanometer contains a coil of wire in a magnetic field, which will experience a torque when a current passes through the wire of the coil.  The coil is attached to a pointer and a spring so that the amount of deflection of the pointer is proportional to the current in the wire of the coil. The value of the load resistor (R 1 ) will be set to a specified value and the potential difference provided by the power supply will be varied to obtain a full-s
