But I digress, today I tested out the ultrasonic and its readings with the Arduino IDE, it works fine, except for one big problem. The pom pom seems to bounce off/disperses the sound waves so the readings return -1, nothing is detected. In order to fix this I simply made a new target out of green card-stock, a 4 cm by 4 cm by 4 cm cube.
The arm itself is working fine after testing it out with an old program of mine that allows a user to manually control the arm's servo with keyboard inputs. I need to figure out the right sequence for the shoulder and elbow to move in order for the claw to be position in front of the target cube to grab it without hitting the target cube while the arm lines itself up.
I found out a crude hack for connecting the lipo battery to the breadboard with some simple jumper wires. However, I'm still waiting for a proper charger for the battery to arrive from shipping. I tested if the buck converter was still outputting 5 V with my multimeter since the lipo battery pumps out around 15 V (out of the box) and the buck converter is returning a close 4.9 V.
That's about it for tonight! I'll post some pictures of the new target object with the arm and the battery in the morning.
