Two other tutorials I have written step you through the basics (Arduino 101) and how to create a really basic data logger (Arduino Datalogger – simple). This tutorial will step through how to attach servo motors, and use temperature sensor to move it! The premise is that often, you want to respond to some input
Temperature and Servos Continue Reading
Still on the journey to complete an “upcoming project”, “ESP32 NTP Temperature Probe Cooking Thermometer With Steinhart-Hart Correction and Temperature Alarm” is an Instructable showing how I add an NTP temperature probe, piezo buzzer and software to my capacitive touch Instructable “ESP32 Capacitive Touch Input Using “Metallic Hole Plugs” for Buttons” to create a simple
In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time.

As Engineers/Developers we always rely upon the data collected to design or improve a system. Recording data and analyzing them is a common practice in most of the industries, here we are building Arduino Data Logger Project where we will learn how we can log data at a specific interval of time. We will use

A note on what this document covers The key addition to the wealth of online information about pulse counting is the method of counting pulses from multiple sources (up to 12) using continuous sampling and direct port manipulation in an Arduino sketch instead of interrupt-based counting. When tallying pulses from one or two pulse output
Reading pulses from meters with pulse outputs.. using arduino Continue Reading
Here is a simple tutorial to build a Distance sensor which will show the distance from the distance sensor HC-SR04 ( Or any other compatible devices) to the wall or obstacles in front of the sensor in CentiMeters. This project uses a HCR-SR04 distance sensor and atmega 328 or any other atmega chip which is programmed

Overview Jump to the Table of Contents This is a simple board for measuring temperature. It uses an AD595 chip to make thermocouple measurements easy. The AD595 amplifies the thermocouple signal and conditions it for easy use. Thermocouples are great due to their linearity over a large range, and their high temperature capability (up to

The HMC5883L magnetometer This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth’s magnetic field. This magnetometer HMC5883L has within 3 magneto-resistive sensors arranged on three perpendicular axes (the Cartesian axes x,
