This TCRT5000 Single Channel Line Tracking Sensor Module is a great detector for a line-following robot. Potentiometer to adjust the sensitivity of the individual sensors.
TCRT5000 Single Channel Line Tracking Sensor Module is a carrier board for TCRT5000 reflective optical sensor. Although it is designed for use with line-following robots, it can be used in mini-sumo robots for line control. The board has a digital output.
The concept of working of line follower sensor is related to light. We use here the behavior of light at the black and white surface. When light fall on a white surface it is almost fully reflected and in case of black surface light is completely absorbed. This behavior of light is used in building a line follower sensor.
Each phototransistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0 V and VIN (which is typically 5 V) as a function of the reflected IR. The lower output voltage is an indication of greater reflection.
This JoyStick Shield Module Robotics Control is an Uno compatible shield that allows you to turn an Arduino Uno or compatible into a game console or robotic controller. 3.3V to 5V Gamepad Joystick Shield Module Game Rocker Button Controller Expansion Board For Arduino Simulated Keyboard Mouse Module.
The shield sits on top of your Arduino and turns it into a simple controller. 7 momentary push buttons ( 4 big buttons + 2 small buttons + joystick select button ) and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers.
CNC shield V4 needs to work with the Nano board. It can be used as a drivers expansion board for engraving machines and 3D printers. It has in total 3 channel slots for A4988 stepper motor driver modules (not included) for driving 3 channels of stepper motors.
Each channel of stepper motor only needs 2 IO ports, which means 6 IO ports are sufficient to manage 3 stepper motors. This shield can make quick work for managing stepper motors in your project.
You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! Here is the Servo Driver Module Shield 16 Channel to help you out!!!
What now? You could give up OR you could just get our handy PWM and Servo driver shield. Its now Arduino-ready and works with any Arduino that uses shields: Uno, Mega, ADK, its all good.
