-==== Sensors ====
+----
-Every sensor on the board is connected through the jumper, enabling to select between on-board sensor or external sensor which can be connected to the same port on the CON2 connector. By default all on-board sensors are connected to the analogous inputs of the microcontroller (ADC0-ADC3). In addition to on-board sensors, several analogous external sensors can be connected with sensor board through the connection CON2 to ports ADC4-ADC7. Attention have to be paid to the fact that the ATmega128 is using same ports (ADC4-ADC7) for JTAG programming. Both functions cannot be used simultaneously, the microcontroller can be configured to use just one. Both functions cannot be used simultaneously; the microcontroller can be configured to use just one. However if there is a need to use e the external sensors together with JTAG program, they can be connected to ports ADC0-ADC3, but appropriate jumpers have to be shifted.

-==== Low-pass filter ====
+----
-Low-pass filter can be composed between analogous inputs 0-3 (PF0-PF3). Resistor and capacitor will be connected to the socket for building up the low-pass filter. By default a low-pass filter is composed for the channel 0 (PF0). Resistor value is 10 kΩ and capacitor value is 100 nF.

-===== Connecting the module =====
-While connecting the module it is suggested to follow the order as described below. Before connecting any cable make sure that the power is removed from Controller board.
-  - Connect the Sensors module with Controller module by using the ribbon cable. NB! Check that the ribbon-cable is connected to the CON1/PF connector - not CON2
-  - If needed connect the infrared distance sensor (black wire to GND)
-  - If needed connect the Digital i/o module with LCD.
-  - If needed connect the ultrasonic distance sensor with Digital i/o module (black wire to GND)
-  - If needed connect the JTAG programmer with Controller module.
-  - Connect the power supply with Controller module.
