In this tutorial, we will build a circuit with Arduino Uno that can read voltages from 0 to 30V DC and display them on the 16×2 display, the ideal project to build our DIY voltmeter. Thanks to the analogue inputs, that can be used to measure voltages from 0 to 5V. For higher values ​​we…
As stated on the title, in this tutorial, we will rotate a motor in both directions. To achieve this, we can use a switch or the serial monitor. We will need an integrated circuit chip (IC), called H-Bridge, we will use a L293NE or SN754410 chip for our experiment.
A breadboard is a device for testing temporary electronics projects. Components used to test a circuit can be reused for other projects. None of the components are damaged.
Almost all people start to learn electronics using breadboard because it is the simplest way of making circuit. The photograph shows a typical small breadboard which is suitable for beginners building simple circuits with one or two ICs (chips).
The TSRW430 provides a four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered from a 12VDC supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 1A at 12VDC. The relays are SPST-NO types. It’s a Wi-Fi…
In this tutorial, we will learn to connect and use the RTC (Real Time Clock) module to display date and time on the 16×2 LCD display. DS1307 is called the Maxim-Dallas module for Arduino with which it allows us to have a precise system clock.
About FTDI FT232RL breakout board:Â This tutorial is about making Arduino on breadboard using a basic FTDI FT232RL based breakout board.The pinout of this breakout board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is…
Bluetooth profile is a wireless communication interface that connects Bluetooth devices. The profiles define requirements for implementing of Bluetooth for various applications, such as, file transfer, wireless headset usage, etc. The following figure depicts different Bluetooth profiles and their usage.
This project includes 10 LEDs of 1W each, and provides high intensity lighting that can be used in various applications. The board is made in Arduino shield form and can be used with Arduino Uno or Mega. Each LED can be controlled individually connected to digital pins D2-D11 of Arduino. Circuit requires 9-12V supply, it…
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
Enable/Change The BT Pair number All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. The default bluetooth name is “BT SPEAKER”. Maybe you want change it to a special name or add a password to this module. We just updated the AudioB plus design…
We all know that troubleshooting is a process of identifying and solving problems that cause a circuit to malfunction. This article is about troubleshooting basic and amateur electronic projects, not about sophisticated devices . With the exception of minor problems,troubleshooting sophisticated systems at the circuit level, like computer, VCR, mobile phones, etc. requires special skills,…
In this project, we will learn to experiment with LDR and a buzzer. The output of this experiment is sound with different frequencies that are produced depending upon the light falling on the LDR/photoresistor. STEPS – Connect the negative black wire of the buzzer to pin GROUND and the black positive to the digital pin…
