You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

With all the hardware setup completed, connect the Arduino UNO via USB cable and upload the code. Powering it ... To keep it simple, I'm using a 9V battery. Don’t forget to adjust the potentiometer on ...

So, here is a simple Arduino based ... Here three LDR sensors are used to control the brightness of individual Red, Green and Blue LED inside RGB Led. Learn more about controlling LDR with Arduino ...

It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor ... Upload the code into ATmega328 microcontroller on the Arduino board. Testing of the circuit is simple. Point ...

The open source Arduino IDE makes it easy to write the code and upload it to the board ... The working of the project is fairly simple. The voltage across the LDR changes with light intensity, and the ...

First of all, remove the LDR used in the setup, and extend +5-V and A0 connections as depicted in the hardware layout shown below. Also, replace the 10K resistor with a 47K to 100K one — this isn’t ...
