Arduino and nitrogen, phosphorus, and potassium sensor to measure soil nutrient content

Arduino projects, Sensors

In this article, we will introduce how to connect a soil nitrogen, phosphorus, and potassium (NPK) sensor to an Arduino and build an Arduino soil NPK meter. Using a soil NPK sensor and an Arduino, you can easily measure soil nutrient content. Measuring soil N (nitrogen), P (phosphorus), and K (potassium) content is essential for …

USB PIC Programmer Built from Arduino

Arduino projects, Programmers

In my previous article about an SPI Flash and I2C EEPROM programmer built with an Arduino, the very first question/comment after publication was “Does it program PICs?” This question, of course, came from an inattentive reader, but it confirmed once again that although PIC microcontrollers are quite old, they still enjoy considerable interest among hobbyists, …

USB Programmer for AT89C Microcontrollers Based on Arduino

Arduino projects, Programmers

I’d like to share my latest project — a USB programmer for AT89Cx051/AT89C5x microcontrollers, built on what is probably the most well-known and inexpensive development board out there: the Arduino Nano. The programmer’s circuit is fairly simple. Besides the Arduino board itself, it contains a couple of transistors, a diode, several resistors and capacitors, a …

Kitchen timer on arduino

Arduino projects

Kitchen timer on arduino I want to say right away: 1 – I don’t know programming languages. That’s why I use Sergey Glushko’s wonderful program FLProg. 2 – I don’t brag about the code, which most likely turned out to be crooked and unoptimized. 3 – I just want to share my opinion on how a timer can …
