What is the purpose of adding a dead zone to an analog input?, To increase the ADC resolution., To remove faint flicker caused by very small values near zero., To make the PWM output brighter., To speed up sensor readings., Why should averaging be applied before mapping an analog value?, To reduce memory usage., To make the mapped output more stable and reduce bouncing., To increase the maximum ADC value., To eliminate the need for clamping., How can you invert a PWM output if the control direction feels backwards?, Multiply the duty by 2., Set the duty to 0., Use duty = 1023 - duty after calculating the normal duty., Reverse the GPIO pin numbers.
