timerEnd(timer); timer = NULL; } } } The RepeatTimer example is in the Timer submenu, and it illustrates how to create an interrupt handler for the ESP32. The interrupt handler is a function called onTimer and it is attached to the timer and triggered every second. The button is read...

The used IMU MPU6050 communicates using I2C and to keep the libraries happy I decided to stick with the default pins A4 (SDA) and A5 (SCL). I will connect the interrupt pin in case I will need it in the future. Nano supports interrupts on pins 2 and 3 only as can be seenhere. Th...

SKU: ABX00083 Description The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE,...

Failed to run on ESP32 Arduino Core due to watchdog timer reset. 4 pixel horizontal offset when set to 128×32 resolution. Sketch runs only once on Arduino Nano 33 BLE Sense, immediately after uploading. Since Adafruitpublished the source code for this library, I thought I’d take a look...
Equally, the Pi Zero and the Pi Zero W are both 66.0mm x 30.5mm which is smaller than the Arduino Nano which is 18 x 45 mm. As well as the GPIO the Zeros also have USB, Camera and a mini HDMI port. Looking at the big Microcontroller based boards, there’s the Arduino Mega. Thi...
This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important fe
