This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

Conclusion Direct port manipulation in Arduino allows for more efficient and powerful control of the microcontroller's I/O pins. This tutorial has introduced you to the basics of port registers and ...

Two UNO R4s Hop on the Bus! CAN Bus Tutorial for the Arduino UNO R4 The Arduino UNO R4, released in two versions last year, supports the CAN bus in terms of hardware and software. In this article we ...

SIM800L GSM Module Connections (Requires Level Shifting) The SIM800L module needs special attention because it operates at 3.3V logic levels while Arduino uses 5V. We need a voltage divider circuit to ...

Matrix Din to Arduino D11 Matrix CS to Arduino D10 Matrix CLK to Arduino D13 To control the matrix, I used the Arduino LEDControl library, enabling access to individual LED pixels, rows, and columns.

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

After waiting almost a month, I opened up the OLED and went right to testing it out. The link in the description pointed me to this website, which is a tutorial from Adafruit. Apparently, Adafruit ...

Hello, I'm having a problem that's driving me crazy! I use Arduino GIGA and the MKR GPS Shield (m8q) interfaced via serial port. basically when I use your library the BLE (I use the official Arduino ...

With Arduino library support on an ARM Cortex M4 processor, it’s no surprise that we’re fans of the Teensy 3.1. And lately, [Paul Stoffregen] has been building out the Audio Library for… ...
