This Arduino Ohm meter will save you lots of time. Just measure all of your resistors, label them, and you won't need to read color bands anymore. With the Arduino Due and Zero, you can change the analog resolution to a 12-bit number, giving you values between 0 and 4095 if you need more precision. Reply.

This instructable describes a shield, which converts UNO und Duemilanove boards. It can work in three modes: standalone - the measurement data can be seen at the character or graphical LCM connected - the

ARDUINO RF power SWR meter -Use Arduino for Projects

The meter cal pots are repeat-adjusted until at least the S5 to S9 points on the scale are reasonably accurate. Signal strength reports which are usually subjective, can finally be given with the confidence of having a meaningful basis to accepted RF standards.

LTC2990 Datasheet and Product Info - Analog Devices

This circuit can easily measure the very tiny AC voltage and high frequency 100 Hz to 500 Khz. Use an op-amp is the input is mosfet types, so has input impedance about 10 M ohms. The lowest full scale of this meter is 15 mV on a galvanometer 100uA. A galvanometer is a very sensitive meter to measure tiny currents, usually 1mA or less.

Time Electronics 1006 is a portable DC millivolt source suitable for voltage injection and thermocouple simulation. It has a textured grip for comfortable handling and openings at the top and bottom to allow access to the battery meter and a position to place labels if required. It is easy to remove if the user prefers a stand-alone unit or

How to make a Arduino Digital Voltmeter - Mechatrofice

Arduino Uno needs 5 volts power to run, then we need at least 7. 4 volts to 9 volts battery. Since Arduino pins support only 5 volts maximum, then we need a Voltage Divider. you should use your multimeter to test both resistances values. No matter if the meter is precise or cheap model, while it gives you the same values when you test twice

Scullcom Hobby Electronics #32 - Design Digit

2/17/2013The sensor takes 10 V DC in on two wires, and outputs 0-100 mV DC, 1 mV/psi. I need to read that voltage on an Arduino (actually a Teensy), convert it to a PSI measurement, light an LED if it's too low, and output the information over a serial line. I'm OK on the software side of it, at least conceptually, but questioning how to read the voltage.

Design a Luxmeter Using a Light Dependent Resistor

Arduino Voltmeter Sketch Code. The sketch is based on the code from the Measuring DC Voltage using Arduino article. . The sum and voltage variables have been changed into arrays so that they can store values from four analog channels. The voltage calculations work the same way as the original sketch, but now do the calculations for four channels.
