  My father and I are building a golf ball display case and I decided to add some LEDs above each golf ball. I will most likely be using a 9v battery to power the LEDs, but I want the option to use a left over power supply if its possible. Most power supplies I found in my junk drawer are 5v, but 1 of them is has an ...

• Sharp GP2D12 IR Distance Sensors Noise

  
  Electronic Circuits Projects Diagrams Free — Authority: 165
  I am using 2 of these sensors to judge the difference in distance on the two sides. These are then to be read by the ADC of a PIC and compared internally. As a first practice with this sensor I hooked it up 5V and GND and had the analogue out pin connected directly to a scope. Originally I was seeing large (500mV) ...
