Digital side car power

I just want to give a heads up on a problem with a digital side car we had today. We have 3 Sharp IR sensors connected to the digital IO's. We were getting unstable readings from them. Before we had monitored them with a separate micro controller board and they worked fine. We found that we had to add a 100 uf cap across ground and 5+ to get a stable voltage to them. If other teams are having stability problems with the DIO and every thing else is right then the problem may be with the power. Try a cap. We had a similar problem with one analog break out last year.
