Arduino video of turning and spinning motors

Here’s a video of my Arduino robot with some nextrox motors attached to Di servo servos. This is so it can turn and also move forward or backward. https://youtu.be/4bpG65nveMk   Here’s the code:   #include <Wire.h> #include <Adafruit_PWMServoDriver.h> //SERVO SECTION // called this way, it uses the default address 0x40 Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver(); //for …

Robot progress

Here are some pics of my project so far. I got some servo mounts from ServoCity and they are mounted in order to turn the other motors. They turn on carpet in tandem which is pretty cool. I am waiting on a 1/4 20 tap to connect the plexiglass to the 80 20 pieces.

Voltage Regulator for PCA9685 board and 7+ volt power supply

In my previous post https://blog.andytriboletti.com/which-servo-motor-im-using-for-my-arduino-project/ I mentioned I had a problem with the servo controller board I was using. I followed the instructions here: http://wiki.sunfounder.cc/index.php?title=PCA9685_16_Channel_12_Bit_PWM_Servo_Driver It says to use a max of 6 volts. It also says to use -2 x 18650 Li-on Batteries which equal over 7 volts. Since the board started smoking when …

Magic orchid cloning stuff

Amazon recommended me “Keiki Power Pro Orchid Plant Cloning Paste” today. I like orchids. I ran the site through fakespot.com and it got an A. I bought it directly from the company instead of Amazon. I will let you know if it works.   Update 12/2/2018: It didn’t work for me.

Which servo motor I’m using for my Arduino project

I purchased 2 different kinds of servo motors for my robot Arduino project. One on Amazon: https://smile.amazon.com/gp/product/B076CNKQX4 Four on Ebay. They both arrived quickly. I tried using the four on Ebay first. “4PCS Digital MG996R MG995 High Torque Metal Gear Servo For Racing Futaba JR RC”   Eventually the pwm servo driver board I was …
