A project log for Johnny IV

I still have some servos around, ordered some ws2812b rings and bars and an ultrasonic sensor to get into a bit of animatronics

I'm still trying to get the wire mess controlled, to have an easy point to come back on a later point in time. On the backside there will be a PCA9685 16-CHannel 12-Bit PWM Driver board used for the servos and getting along with the ws2812b LEDs. I've heard about timer issues and just wanted to be safe. The red and green boxes are tiny breadboards for arduinos and servos.

I'll update this as soon as the print is done.

I'm not a great fan of the breadboards -- somehow the wires never stay where they were supposed to. Instead I tend to use breakouts with male pins, and stripboards (also with male pins). It seems to me that they give much better connections with female-female dupont cables.

it's just for testing at first and holding the modules in place somewhere. I'll might just solder onto the arduino or make some pinheader plugs later.
