This Instructable is about the programming of an Atmega328 based Arduino. It concentrates on the various aspects of the programming. This Instructable is meant as a reference for anyone trying to program an own detector. This Instructable is not about how to build a metal detector. For this se...
There are also examples of using Arduino for building projects wit the main device in these being the AtMega328p which is broadly similar to the 18F2550. AtmelTM: Made extremely popular by the Open source ArduinoTMgroup. You have probably heard of the ArduinoTMwhich is not a microcontroller ...
is a tiny chip plugged into the Arduino board, and the Arduino board provides a beginner-friendly interface with a USB port, pin headers, DC power jack, among other things to help you program or connect things to it more easily. I encourage you to learn more about the ATmega 328P by ...
If you have a need to re-flash the ATmega16U2 chip with the stock firmware to restore the Arduino UNO back to normal, this is often done on the command line using avrdude or dfu-programmer, or with the Windows program Flip. The easier way for me is to just use the Arduino IDE. ...
PWM control using arduino. PWM control is a very commonly used method for controlling the power across loads. This method is very easy to implement and has high efficiency. PWM signal is essentially a high frequency square wave ( typically greater than 1KHz). The duty cycle of this square wa...
The other Arduino boards discussed so far use a microcontroller that doesn’t natively support USB, so they have included on the board a separate microcontroller that serves simply as a UART to USB converter. The ATmega32u4 used in the Leonardo and Micro instead includes native USB support elimi...
Step 9:Select the COM port at which Arduino Nano is connected: Step 10:Select theOld Bootloaderfor Atmega328P. Go to:Tools>Processor>ATmega328P (Old Bootloader): Step 11:Now upload a blank sketch to confirm the Arduino Nano driver’s installation in Windows: ...
Timer-interrupts are a fantastic way to avoid using the blocking delay()-function call in your Arduino program. Another article discusses the benefits and downsides of using timer-interrupts in your Arduino projects. The second type, called hardware-interrupts, allows you to react to external ...
If we assume only a 1 byte buffer (the ATMEGA328 in the Arduino Uno has 2 bytes), then probably the easiest way to get interrupt-free serial communication working is to make a very simple protocol where every byte sent to the Arduino is acknowledged by a byte send by the Arduino. So ...
This includes the ATmega microcontroller that you will have to program using an Arduino Nano and the Arduino IDE. If you're not comfortable doing this it might be worth buying a build kit and skipping to the fun part of modding your Ploopy. But, for those who are bold enough to start ...
