Voltage generated by pins of Arduino microcontroller board is 5V. Voltages that can be applied
to Raspberry Pi microcontroller boards cannot exceed 3.3 V, otherwise Raspberry Pi board will
be permanently damaged. The so-called voltage level shifting is required. One of the ways how
this can be achieved is by using the voltage divider circuit as shown in a), and schematically
represented in b). Design this voltage divider circuit.
Hint: in the voltage divider formula resistance of one of resistors can be chosen arbitrarily, so the
other resistor value can be computed. In order not to exceed power ratings of resistors use
resistor values not lower than 1 KQ.
