Java or similar programming languages, if you are not, there will be some help provided by the tutorial, but please refer to the electronics and programming resources section. Some electronics knowledge, you need to understand basic electronics concepts such as what voltage, current and a circuit ...
How Do You Check Voltage With a Multimeter? A multimeter is an instrument that can measure voltage, current, resistance and possibly additional parameters. You can also use it to check continuity of cables and check fuses. If you don't know how to use one, read my guide How to Use a ...
There are several possible reasons why a desktop, laptop, or tablet computer such as aSurface Pro fails to power on, so you must step through a complete troubleshooting procedure like the one we've outlined below.
Power cord wire colors are sometimes non-standard so use a multimeter to identify Hot and Neutral. Europeans sometimes use the letters E: Earth (safety ground), L: Line (hot) and N: Neutral to describe the three plug wires. The 325 volts AC power from the power transformer is fed ...
To do this, I put my anemometer in the car and used it to measure airspeed---which should match the speed of the car, assuming I'm not driving in a gale. I followed this plan: Get in the car. Stick the anemometer out the window and hook it up to a multimeter. Drive at ...
1) Position the multimeter in the Ohms range, preferably in the 1K range. 2) Begin by connecting the meter prods to any of the two pins of the relay randomly, until you find the pins which indicate some kind of resistance on th meter display. Typically this may be anything between 100...
Sort of hard to explain which is why I didn't include it in the original post. The decoder (a Loksound v4.0) has an inbuilt 1.8W amplifier, designed for driving a tiny 20mm speaker for use in miniature trains, but I want a higher power output, more volume, bigger speakers e...
