I’m trying to connect a toy robotic arm to my Arduino to make it bend to my Arduino whims. The robotic arm comes with a connector (image attached) which connects into the robot arm body. I believe this is a Molex 8 pin 2.5mm pitch single row from my research, but I’m not too sure
Bigger question is how do I get a fully crimped, ready to plug in to the robot arm and the other end to a breadboard to connect to Arduino? Do people typically buy a connector and then a crimper to do it themselves, or is there a better way of doing this (surely!)
The robot arm has its own power supply (small batteries). This is really just a switch to turn specific motors. The connector in the picture goes to the power supply batteries in the robot arm, while the open end wires the other side go to the arduino
The Arduino cannot possibly act as a switch for any motor. But it can control a MOSFET or a relay to do the actual switching. What are you planning to use?
Yeah I didn’t plan it too ahead, but I’m thinking more of a transistor based switch. So the Arduino will be the base that triggers the actual current from the battery in the Arduino - MOSFET as you said. I’m quite restricted with what I can do given that the robot arm circuit is fixed and I’m just trying to replace the provided toy controller with an Arduino
See the circuit diagram below - I am trying to replace the wired control box with my Arduino
