Nano 33 IoT: Testing battery options and low power mode
•
In this article, I will describe my attempts to minimise power demand in the Arduino Nano 33 IoT and select the best combination of batteries to use. My objective was to build a battery powered environment monitoring station using an Arduino. This might be an outdoor weather station tracking temperature, pressure and humidity or something

Selecting the right Arduino board for battery powered operation
•
I had a fairly simple objective – to build a battery powered outdoor weather station using an Arduino. The very first step, choosing which Arduino board to use, proved to be more complex than I expected. In fact, the array of parameters in my selection matrix kept growing over time as my knowledge increased during

Interrupt Timer for UNO WiFi Rev2 and other ATmega4809 units
•
The usual interrupt timer libraries and examples may not work on the Arduino UNO WiFi Rev2 and Nano Every because they use the ATmega4809 processor. So here is a quick and simple example showing how to use one of the inbuilt timers (TCB0) to toggle a variable that can be checked in the loop routine.

Testing the NRF24L01 with Arduino Nano 33
•
Summary NRF24L01 modules, because of their low cost, are an appealing option for data transmission over modest distances. They are best suited to unobstructed “line-of-sight” transmission, but one might hope at least to reach an adjacent room indoors. Here, I describe my experience testing a pair of NRF24L01 modules, each linked to an Arduino Nano
