Precision resistors, which have more precise values than standard resistors, have five color bands. Four of the bands tell you the nominal value. The fifth band tells you the tolerance. You can count on the actual resistance of a precision resistor being really close to its nominal value. So...
A: These denote EIA preferred values. Gold = multiply by 0.1, silver by 0.01. Q: Can you read a resistor’s value without decoding the color bands? A: Yes, you can directly measure a resistor’s resistance using a multimeter if you need to confirm its value. ...
Combine the values of the different bands to find the one value. So, if you have a four band resistor with the colors red, blue, yellow and brown, you’ll know that your digit value is 26. The yellow is the multiplier and that’s 1000. So, you’ve got 26,000 Ohms. However, sin...
Part 2: Recognizing Names and Values of Schematic Symbols Name:In addition to the symbols, every component on electrical schematics has a unique name and value, which further helps to identify what it represents. Component names are usually a combination of one or two letters and sometimes a nu...
Instead of sending just one byte, can you tell me what resistor values you are using for the resistor divider and what the entire data conversion result is instead of just one byte (preferably in hex)? Also remember early in the thread that...

How to Reduce Voltage to Any Value You may not always want half the voltage, but you can get the voltage to any level you want choosing the appropriate resistor values for a voltage divider circuit. Maybe your circuit is running off of 5V, yet you want only 3V to feed into a particular...
They cost less than 1 cent each, but humble resistors are an essential tool no matter what electronics you are building. In this reference guide we look at using them in projects, and how to identify the correct resistor for your project.
Additionally from this tutorial you have learnt how to: read analog values from the Arduino usinganalogRead() understand and manipulate the value returned from theanalogRead()function use a a voltage divider circuit to read changes to a resistor based sensor such as the thermistor ...
A resistor is an electrical component that is used to create resistance in circuits. This resistance can be utilized in many ways, like dividing the voltage or reducing the current. There are many types of resistors. However, the one that we're going to work with in this article is the m...
