 | | Converting voltage to resistance
|
| This is a dumb electrical question. I am a programmer, and I still struggle with the electrical aspects of this hobby. How do I convert voltage output to resistance. I have an application that turns out 0 to +5 volts. However, as I read the (...) (27 years ago, 2-Mar-00, to lugnet.robotics.handyboard)

| (...) Fortunately there is a direct relationship between servo-value and angle. Try different angles (for example 0 / 45 / 90 / 135 / 180 degree) and draw the diagram value vs. angle (for example with MS Excel). You will (hopefully) see a linear (...)

| | |  | | RE: HB's mA consume?
|
| Well, you can _greatly_ increase the efficency of the handyboard if you remove the 7805 regulator and replace it with a PowerTrends switching regulator (Digikey sells these among others). I would suggest you run three wires from the regulator to the (...) (27 years ago, 1-Mar-00, to lugnet.robotics.handyboard)

|
| Thanks your answer Will, well, seems not easy to give a good use to a solar panel in the HB If I want to connect the a panel to the HB charging circuit, it must be 12V/500mA like the AC adaptor? or with less current (maybe 200 mA) , it can still use (...)
