Contrast sensor module. It has two integrated operating modes: analog and digital. In analog mode, it returns a voltage value between 0 and 5 V proportional to the detected gray level. In digital mode, it returns a value of 1 or 0 depending on the detected substrate. Detection attempts can be modified with a simple procedure (described in the manual) and a button placed on the board. The user manual and sample programs are available on the Wiki page.
Data sheet
Arduino Uno Rev3 is a popular board with Atmel ATmega328 microcontroller from the AVR family, there are 14 I / O lines, 6 PWM channels and 6 analog inputs. The additional ATmega16U4 microcontroller realizes communication via the USB interface. Arduino A000066
2WD miniQ robotic platform is especially designed for students and hobbyists. It\'s versatile and small, suitable for most indoors applications. It features high quality and powerful metal gear motors which make it a speedy robot. It is ideal for maze competition and educational courses, and is very easy to assemble. ROB0049
Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265
