My Commentary and Technical help

My latest creation uses dual 80x160 RGB LCD's to produce two robot eyes.  They are wired together so they can not "wink".  On ...

Improved the Arduino Robot Face by putting it on a 2.4 inch Parallel LCD. The LCD is a HY-TFT240 to be exact. This larger 320 by 240 LCD g...

 I thought I would try using a Nokia LCD for creating a face for my robot.  However I was greatly disappointed.  If you make his eyes white,...

I have started on making my third humanoid robot.  This one is modeled after the EZ-Robot JD Humanoid.  The issue with the larger humanoids ...

I am working on making some better "eyes" for my humanoid robots. The 8x8 LED design was cool but I can do a lot more with an LCD...

 In my book "Arduino Servo Projects" I made all kinds of Humanoid Robots.  But none of them were the 17 DOF Humanoid as is found o...

This change started as an accident.  Somehow I broke one of the variable resistors that controls the servos in the arm.  So after a while I ...

There was not enough pins available on my Arduino UNO to interface a LCD.  I was using 15 pins to control the servos.  So I added a PCA9685 ...

 I am working on different options for the head or face of my 15 DOF robot.  Today I got a MAX7219 8x8 LED array working with it.  Over the ...

  I have finally been able to run this robot.  I started the project about a year ago.  There was one bad servo that needed replacement.  Th...

I rewired another of my signs to have all of the LED's wired in series.  They will work with an ESP8266 or newer processor wired that wa...

This summer I had purchased a LED sign.  On a closer observation I discovered that I cannot read the model number.  The sign contains two LE...
