- Problem 4 a) PEFF R₁ AAA b) Vs 5 V wwwwww R₁ R₂3 Vout 3.3 V 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.14 10 Ω 2 Q 15 2. 1290 16 C D 11 V 1Ω 1 5Ω 10V 13 Ω Dr. Ben Blalock asks that you solve for the currents as shown.
