Small Caster Wheel Other Current Transfer Ratio (CTR): 50%

Current Transfer Ratio (CTR): 50% to 600% (typical)

in testing and fabrication you need to physically connect and test the system you have developed with the different components either on breadboard or perfboard in any way you like but doing this means you have to make many a connections and sometimes these connections will become very tough to trace and also if you are not good at soldering then the connections might remain loose and that means your system might malfunction

GY-511 module includes a 3-axis accelerometer and a 3-axis magnetometer

LED Cathode 4

This sensor can detect a variety of flammable gas

Small Caster Wheel Other Current Transfer Ratio (CTR): 50%A simple ball castor wheel that can rotate in all directions. It is commonly used as a front wheel in differential driven robots. The ball bearings inside it provide smooth rotation of the wheel enabling less drag for the robot. Can be found in line follower, obstacle avoider and other robots. It can be mounted under robots or other larger objects to enable easy movement or rolling of the robots or objects. Specifications of the Castor Wheel Centre
