We Can Use the On-Board ADC to Convert Number Between 0 and 1023 Rotating Shaft. Here is How to Make LED ON One at a Time Using a Potentiometer With Arduino. That means, as we will turn the shaft of the potentiometer, LEDs will turn on depending upon the position. Actually before this project, one should get used with two basic examples on official Arduino website … [Read more...]
What is I²C Protocol? Relevance of I²C in Arduino
Previously, we discussed about UART. What is I²C Protocol? I squared C (also pronounced as I-two-C) or I²C is a bus serial communication protocol designed by Philips for home automation and home electronics applications. Since 2006, licensing fees not needed to implement the I²C protocol. Fees needed to obtain I²C slave addresses allocated by NXP. I²C can connect a microprocessor and various … [Read more...]
Blink LED and Beep Every 1 Second With Arduino
Previously we have shown beep with key press and LED lightening up and projects like Arduino Traffic Light, Arduino TM1637 with RTC. Here is How To Blink LED and Beep Every 1 Second With Arduino. We Will Discuss Many Ways To Achieve The Goal Including Using RTC. Arduino has many ways to count time. Easiest we know is usage in the way we Blink a LED as basic example. Blink LED and Beep … [Read more...]
Solid-State Relay (SSR) For Arduino
In our one previous article we discussed about Arduino Relay Modules. Solid-state relays are not really relay rather are electronic components which has some functions like electromechanical relay. Here is an Article on Solid-State Relay (SSR) For Arduino. Solid-State Relay (SSR) provides limited switching arrangements (SPST switching, terminologies like SPST discussed on our article on electrical … [Read more...]
Arduino Basic Piano For Children (Pushbutton & Buzzer)
In Early '90s Technology Was Limited and Worldwide there Were Few Electronic Toys. This kind toys with 8051 or plain common IC were easy to find. This particular project is not created by us. This project is shared by ExeCuteLi on hackster.io who deserves the full credit. Here is His Arduino Basic Piano For Children With Pushbutton & Buzzer as Components. The original project on hackster.io … [Read more...]
LDR Reading on TM1637 : Example How To Print Analog Sensor Value
Printing serial display is a difficult or time taking work on particular desired display in Arduino project. Te reason is mostly out of cheap China sub-standard components and fight with community made various libraries hunting driver IC. New users often think that issue their fault. No, that difficult is not logical fault. In Case of LCD, Printing Actually Easy. Like We Have Shown Printing LDR … [Read more...]
Control Multiple LED Depending on the Level of Light With Arduino
In our previous guides, we have shown how to control single LED depending on light with Arduino. Also, we have shown that without Arduino, can control LED depending on the level of light. The ways are different but essentially both involves a basic component - LDR. In this guide, we will show how to control multiple LED depending on the level of light With Arduino. It means - with increasing … [Read more...]
How To Set Up Real Time OS FreeRTOS on Arduino UNO
In our previous articles, we discussed about microprocessor, ARM architecture, kernel of operating system, UNIX, Linux, Difference Between Real Time OS (RTOS) and Embedded Linux etc topics. Here is How To Set Up Real Time OS FreeRTOS on Arduino UNO. Although Sounds Challenging, it is Simple Dropping Directory and Including Via Code. Arduino UNO has Atmel AVR. FreeRTOS officially support AVR. … [Read more...]
Make Beep Sound in Arduino Project Upon Push Button Press
It is Practical For Many Projects Including LED Clocks. We actually expect some visual, auditory feel along with tactile feel. Normally, we create sound on Arduino in complex way as the sounds has lot of pitches. But here, we just need a simple sound, so the circuit and code is easy and ready to be adapted inside other projects. Here is How to Make Beep Sound in Arduino Project Upon Push Button … [Read more...]
Difference of Arduino Due With Other Arduino Boards
In our one previous article, we discussed about STM32 ARM Cortex M3 Boards which can run Arduino. Arduino Due is basically official version of those boards. The bootloader is preburned in factory from Atmel and is stored in a dedicated ROM memory.Difference of Arduino Due With Other Arduino Boards is the 32-bit ARM Cortex M3 Microcontroller Which Forces the Board to Supply Maximum of 3.3V. The … [Read more...]
Arduino Compatible STM32 Boards (ARM Cortex Boards)
Arduino Compatible STM32 Boards Has Dual Advantage of Being Arduino Compatible and Also Support For ARM Cortex Way of Programming. Of course they are cheap & Powerful than Arduino official boards. There is too many things to know before purchasing Arduino Compatible STM32 Boards, unlike native popular Arduino boards with onboard USB and popular bootloader. As most of them manufactured in … [Read more...]
