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...]

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...]

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...]

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 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...]

Made in China, Taiwan Servos Like TowerPro 5010 Servo Not Uncommon to Die. Here is How To Troubleshoot Servo Not Working With Arduino. The tools needed to check a servo is not easy to reach by a common hobbyist. Not all the hobbyists has huge knowledge around PCB inside the servo. Except genuine Arduino board, nothing purchased which are Made in China or Taiwan has … [Read more...]

Previously, we talked about basic on the article multimeter for dummies. Technically You Should Know Formulas, Coding and Use Multimeter For Confirmation, Like Resistors Have Standard Coding. Which Kind of Multimeter Electronics Beginner Should Buy? Any Multimeter Which Works. By beginner, we are taking towards hobbyist not an engineering student. $3 multimeter is better to have for a hobbyist … [Read more...]

Among LED displays, it is TM1637 which is popular. When digits become more than 4, we need MAX 7219 IC, which is costly but commonly used. The cost makes 8 digit 7 Segment LED Display less commonly used. 14 Segment LED Display is almost exotic in programmable microcontroller world, because of less availability and higher cost of driver IC. Here is Information About Arduino 14 Segment LED Display … [Read more...]

It Prudent to Use Fuse When Basic Matter Around Fuse is Known. Without Knowing Using Fuse Provides False Sense of Security. Here is Basic Details on Breadboard Fuse Holder and Fuse For Arduino Projects. It is practical to read our previous article on Types of Fuses, Fuseholders Used in DIY & Household to get an idea about what are the names of fuses. In this article, we will talk about … [Read more...]

In our one previously published article, we discussed about Prototype Boards. Prototype Board - How To Use is a Common Question. At least, that is what one commonly searched question on our website. The Answer Depends on Type of Prototype Board (like Adafruit has a breadboard looking prototype board), the Need, Components and Of Course the Circuit. It is not that soldering is the only way, we can … [Read more...]
