Reflectance sensor consisting of array 7 QTRX optocouplers with the ability to individually control the brightness of each of the infrared LEDs. The sensors on the board are high density (HD) and the distance between them is 4 mm. The module can be supplied with the voltage ranging from 2.9 V to 5.5 V and draws current up to 17 mA. The optimum distance from the sensor to the ground is 10 mm and the maximum distance is 40 mm. The module is ideally suited for detecting changes in light reflection, so it can be used for edge detection or line tracking in linefollower robots.
Data sheet
The A-Star 32U4 Mini ULV is a programmable module based on the ATmega32U4 from Atmel. Unlike competing products, it has an onboard switching step-up regulator that allows it to be powered efficiently from a 0.5 V to 5.5 V supply. Pololu 3102
KAmodMPC17C724 is a module with a double MP bridge bridge type MPC17C724. The system allows you to control two DC brush motors or one bipolar stepping motor. The controller operates at a voltage range of 2.7 - 5.5 V and can work with motors with power consumption up to 0.4 A.
4WD car chassis construction kit. It can be used as a base for building a robot
This IR LED/phototransistor pair is great for precisely identifying changes in reflectance. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 80 mm.
