The DS18B20 is a digital thermometer provides 9bit to 12bit Celsius temperature measurement, this device has an alarm function with nonvolatile that user can program upper and lower trigger points. DS18B20 communicates over one wire bus or one data line
Wiring the 14CORE 37 Sensors for Arduino & Raspberry Pi
This is the 14CORE sensor set for Arduino, Raspberry, AVR, STM, Bagelbone, and BananaPi also compatible to most popular IOT modules like ESP8266 and LinkOne. These kit consists of 37 individual modules which can be used to carry out many
Wiring Reed Switch Module with Arduino Microcontroller
On this illustration we will going to wire the Reed Switch Module. This module provides an analog as well as digital interface, as you can see on the board it has a potentiometer / trimmer used as a pull up
Working on Debounce / Interrupts on Switch with MCU
Switch are standard input to any electronic projects. Tactile switch works well in a PCB also can be used on a solderless breadboard. Switch are normally open or disconnected and when the push button is pressed are momentarily closed. Tactile
Programming / Flashing Latest Firmware on ESP8266 NodeMCU DevKit with Mac OSX
NodeMCU devkit can be flashed with latest firmware using your MAC OS, before you going to start you need to disable the OSX “KEXT SIGNING “ feature. Apple OSX introduce the system integrity protection that disabled the modification system location
Wiring The Laser Transmitter on Photocell with Microcontroller
Another illustration how to build a simple physical intrusion detection with laser and photoresistor (or light-dependent resistor, LDR, or photocell). This guide shows how to wire and build a laser tripwire that triggers an alarm or output when the laser
Wiring the TCRT5000 Reflective Optical Sensor Module
This is the Line Tracking Sensor designed for line following robots. The board has two main components IR Transmitter and IR Receiver in one package named TCRT5000. The TCRT5000 are reflective sensors which include an infrared emitter and photo-transistor in
OLED Voltage Meter on Voltage Divider
Another illustration that demonstrate the uses of Analog to measure the voltage of an external battery and integrate the area under the curve to arrive at the useful capacity of a battery mAH. If you’re going to calculate the desired
Wiring the E18-D80NK Infrared Distance Ranging Sensor
In this illustration we will going to wire the Infrared distance switch, a high-sensitive photoreflector to detect distance function, ranging from 3cm to 80cm. When the infrared emitted by the emitter it will get reflected on a surface blocked it
Make your own sound activated switch on Arduino
In this illustration we will going to wire the microphone module, relay and the Arduino board. These project is compatible on most common microcontroller, the main objective of this project to make a sound activated switch or a clap switch.
Wiring the Soil Moisture with Arduino
In this illustration we will going to wire the Moisture Sensor. These sensor can be used as a soil moisture to detect water level on the soil, if the soil moisture is depleted it will send a signal to HIGH.
Scanning i2C Device Address on Arduino
In this guide we will going to find and detect i2c address on our i2c device. You can scan and find the i2c address used by your devices by find the exact address used by the i2c device for more
