Don’t you just hate it when dev boards have some annoying little quirk that makes them harder to use than they should be? Take the ESP32-CAM, a board that started appearing on the market in early 2019. On paper, the thing is amazing: an ESP32 with support for a camera and an SD card, all for less than $10. The trouble is that programming it can be a bit of a pain, requiring extra equipment and a spare finge ...

Well most of time i get troubled when i need Arduino in some projects where i need few I/O pinsWell thanks to Arduino-Tiny platformArduino program can be burned into the Avr-tiny Series like Attiny 85/45 Arduino-Tiny is an open source set of ATtiny "cores" for the Arduino platform. It provides a core that enables Arduino users to work with the ATtiny84 (84/44/24), ATtiny85 (85/45/25), and ATtiny2313 (4313) ...

How do you clean the residual flux off your boards? There are plenty of ways to go about the job, ranging from “why bother?” to the careful application of isopropyl alcohol to every joint with a cotton swab. It seems like more and more people are turning to ultrasonic cleaners to get the job done, though, and for good reason: just dunk your board and walk away while cavitation does the work for you. But jus ...

In this instructable I will show you how to make your own professional looking arduino shield. In the proses of designing the arduino shield I will use eagle.cad, arduino software & viewplot. First step in making a arduino shield is thinking of what you want it to be. depending on what your shield is going to be will vary the parts that you will need for it. PS: the picture is a sneek peek  on my new ar ...

Hello everyone. Today I am going to show how to program arduino pro mini using arduino uno. If you already had a arduino uno and you newly buy arduino pro mini then you don’t need to buy the USB to serial converter to program the arduino pro mini because you can program pro mini using your arduino uno board. We can make pro mini to act as a central ic for arduino uno board. First of all you have to know whi ...

We love the Arduino board and it's prototyping platform . It makes the complete prototyping process smooth and enjoying with the help of it's add on such as Arduino IDE and a huge community support.But sooner or later you will find that the specifications provided by the arduino boards is not enough . And then the problem arises about which board should we use so that our desires are fulfilled.Also How easy ...

During Embedded World 2017 in Nürnberg I was lucky to get a handful LPC800-DIP boards. To get all students who were lucky to get one, here is a tutorial to make that very exciting ‘blinky’ application on that board: MCUXpresso IDE Series This article is part of a series to get up to speed using the new NXP MCUXpresso IDE. Published so far are: MCUXpresso IDE: Unified Eclipse IDE for NXPs ARM Cortex-M Microc ...

Castellated Edges Castellations are small plated edges, typically used for making circuit boards into small pcb modules. These are often seen on wireless modules, such as the ESP8266-12E. While we don’t offer full support for castellations, they can be fabricated if you don’t mind a few minutes of rework and verification of the PCBs. Design Considerations It’s helpful to include a fallback hole near the edg ...

Theremin is an early electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Russian inventor, Léon Theremin, who patented the device in 1928. A typical theremin musical instrument is shown in Fig. 1. This article explains how you can build an optical theremin using an Arduino Uno board and some readily available components. Etherwave ...

Motor starter reduces the load, torque and current surge of a motor during startup. On starting, the motor takes more than five times the normal running current. This overheats the motor’s armature winding and creates a sudden voltage dip in the power supply, which can be avoided by using a motor starter. There are many types of motor starters. Here we describe an electronic DC motor starter using Arduino U ...

Described here is a simple way to load a program without bootloader. An additional thing needed is a USB to Serial/UART/TTL adapter (3.3V level). Connect the USB to Serial board as follows, and power up the STM32 board from a USB port/power supply. • RXD – A9 • TXD – A10 • GND – GND I assume you have already installed the Arduino IDE. Next, you need to go to ‘Board Manager’ under ‘Tools’ and install the sup ...
