The wireless module offers an AVCC output pin for analog devices. To reduce power consumption, the AVCC pin is pulsed so that the pin is only turned on when the ADC module is sampling inputs. Output pulses are approximately 2ms long, and the frequency is 100Hz; this means that AVCC is on 20% of the time. Pulses work great with potentiometers, but Hall-effect sensors might not work with pulsed AVCC if Hall-sensor power-on time is too long. As a result, any excess capacitance must be avoided in the AVCC pin. <br> <br> | The wireless module offers an AVCC output pin for analog devices.

− | The backup option is to provide VCC for Hall-sensors is to power it from the 3v VDD pin and use MOSFETs connected to the SLEEP pin so Hall-sensor can be powered off while Wireless Wheel 2 isn’t connected. SLEEP pin is high when Wireless Wheel 2 is connected to Simucube. See the example in the picture | + | The backup option is to provide VCC for Hall-sensors is to power it from the 3.3v VDD pin and use MOSFETs connected to the SLEEP pin so Hall-sensor can be powered off while Wireless Wheel 2 isn’t connected.
