Don't forget your pull down resistors

Last night I sat down and wrote a bit of code to test the experiment PCBs. I have a servo, a DC motor, (ran by PWM from an analog input) to adjust the duty) and the LED connected to pin13 working. I did notice that I forgot my soft pull down resistor on the digital input switch that I added. OOps. Blue wire to the rescue, should be easy enough, there is a ground trace close to the switch that I can tie a 1k0 smd if I scratch the coating off the trace and drop some slobber.

If anyone is following my other project, you will notice that these logs are very similar. If you don't like it, please feel free to add a comment and I will correct my way of working.
