Maker Line is a line sensor with 5 x IR sensors array that is able to track line from 13 mm to 30 mm width. The sensor calibration is also simplified. There is no need to adjust the potentiometer for each IR sensor. You just have to press the calibrate button for 2 seconds to enter calibration mode. Afterwards you need to sweep the sensors array across the line, press the button again and you are good to go. The calibration data is saved in EEPROM and it will stay intact even if the sensor has been powered off. Thus, calibration only needs to be carried out once unless the sensor height, line color or background color has changed. Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently, which is similar to conventional IR sensor, but you get the benefit of easy calibration, and also one analog output, where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required while building a line following robot with PID control. Features Operating Voltage: DC 3.3 V and 5 V compatible (with reverse polarity protection) Recommended Line Width: 13 mm to 30 mm Selectable line color (light or dark) Sensing Distance (Height): 4 mm to 40 mm (Vcc = 5 V, Black line on white surface) Sensor Refresh Rate: 200 Hz Easy calibration process Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position. Support wide range of controllers such as Arduino, Raspberry Pi etc. Downloads Datasheet Tutorial: Building A Low-Cost Line Following Robot

The Maker pHAT is the solution to the most common problems beginners face starting with Raspberry PI. Its intelligent and simple design makes it easy to attach to your Pi, and it helps you avoid all the tedious work of connection various other accessories. Additionally, the LEDs corresponding to each pin makes it extremely easy to see where a potential problem lies The Maker pHat has the same size as the Raspberry Pi Zero with all 4mounting holes aligned. However, it can be used with Raspberry Pi 3B, 3B+ and 3A+, by inserting a 2 x 20 stacking header. Features Raspberry Pi Zero size, stack perfectly on to Raspberry Pi Zero Compatible with standard size Raspberry Pi 3B / 3B+, medium size Raspberry Pi 3A+ and smaller size Raspberry Pi Zero / W / WH. Standard Raspberry Pi GPIO footprint. LED array for selected GPIO pins (GPIO 17, 18, 27, 22, 25, 12, 13, 19). 3x on board programmable push buttons (GPIO 21, 19 and 20, need to configure as input pull up). Onboard active buzzer (GPIO 26). Proper labels for all GPIOs, including SPI, UART, I2C, 5V, 3.3V, and GND. Utilize USB Micro-B socket for 5V input and USB to UART communication. USB serial facilitated by the FT231X Input voltage: USB 5 V, from a computer, power bank or a standard USB adapter.
