Battery capacity measurement using Arduino [Lithium-NiMH-NiCd] - Technology -PCBway. By Hesam Moshiri, Anson Bao Features: Identify a fake Lithium-Ion/Lithium-Polymer/NiCd/NiMH battery Adjustable constant current load (can also be modified by the user) Capable of measuring the capacity of almost any kind of battery (below 5V) Easy to solder, build, and use, even for beginners (all components are Dip) An LCD user interface Specifications: Board Supply: 7V to 9V(Max) Battery Input: 0-5V(max) – no reverse polarity Constant Current Load: 37mA to 540mA(max) – 16 Steps – can be modified by the user The true measurement of a battery’s capacity is essential for many scenarios. 1: Circuit Analysis Figure 1 shows the schematic diagram of the device.
Figure 1 Schematic diagram of the battery capacity measurement device IC1 is an LM358 [1] chip which contains two operational amplifiers. Figure 2 The PWM signal (CH1: 2V/div) and the result after passing through the R5-C7 RC filter (CH2: 50mV/div) A 2*16 LCD is used as a user interface which makes the controlling/adjustments easy. 2: PCB Board.
ESP8266. Three Methods to Filter Noisy Arduino Measurements | Coding | MegunoLink. Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. Maybe it comes from electrical noise: the random variations you see when calling analogRead on a sensor that should be stable. Noise also arises from real effects on the sensor. Vibration from the engine adds noise if you’re measuring the acceleration of a go-kart, for example. Filters We’ll use MegunoLink to compare three different filters: AveragingRunning averageExpotential filter MegunoLink’s Time Plot Visualizer will be used to show both the raw, unfiltered, data and the output from the filter. Something to Filter To generate some ‘noisy’ data for filtering a thermistor was connected to analog-input 0 on an Arduino Uno. The temperature measured using a thermistor connected to an Arduino was plotted in MegunoLink. To measure temperature, the analog value was read.
After applying the various filters, the data was sent to MegunoLink for plotting: Averaging. Controlar Arduino vía web con Firmata y JavaScript. Free Online Solar Class. In this hands-on beginner class, you'll learn fun ways to harness solar energy in your own backyard, then level up to soldering solar powered electronics projects. Each lesson builds in complexity, stocking your personal library of maker skills with a few more techniques you may not previously have discovered. You'll start simple with a trash bag solar balloon, demonstrating thermal energy collection resulting in buoyancy as the black balloon floats on its own. Then you'll learn how to engrave organic materials using custom stencils and a magnifying glass to concentrate the sun's light. The last few lessons focus on solar panels and solar power, where you will build a solar USB backup battery, and then a soil moisture tracker. By the end, you will gain takeaways for applying solar power to your own electronics projects, too.

How to Interface GPS Module (NEO-6m) with Arduino. 1. Information about GPS What is GPS The Global Positioning System (GPS) is a satellite-based navigation system made up of at least 24 satellites. GPS works in any weather conditions, anywhere in the world, 24 hours a day, with no subscription fees or setup charges. How GPS works GPS satellites circle the Earth twice a day in a precise orbit.
Each satellite transmits a unique signal and orbital parameters that allow GPS devices to decode and compute the precise location of the satellite. To calculate your 2-D position (latitude and longitude) and track movement, a GPS receiver must be locked on to the signal of at least 3 satellites. Once your position has been determined, the GPS unit can calculate other information, such as: SpeedBearingTrackTrip distDistance to destination What's the signal? GPS satellites transmit at least 2 low-power radio signals. A GPS signal contains 3 different types of information: 2. 3. The NEO-6M GPS module is shown in the figure below.
