Arduino Video Tutorials
Sorry for it being such a long time since my last post. I have been so busy with other non-Arduino related things that I’ve barely had time to update the […]

8MHz Node Test
I’ve resurrected the Sensor Node project and I am experimenting in reducing the power consumption even further. This time I’ve removed the 3.3v voltage regulator from the circuit and I’ve […]
ATMega328P Power Saving Techniques
I was sent a link to to the following great article on power saving techniques for microprocessors and in particular the ATMEga328P which is the chip used in the Arduino. […]
Arduino Guide
I’ve added a page to the blog that includes a link to my famous Complete Beginners Guide to the Arduino. It’s a few years since I last updated it and […]
7mA in Sleep Mode
I appear to be getting 7mA current draw when the MCU is in sleep mode. This is not good. Even if left in sleep mode the battery would die in […]
No obvious increase in battery life.
After powering the sensor via a digital pin on the ATMega (see my last post) I can’t say i’ve noticed any increase in battery life. With a read and transmit every […]
Pin Powered Sensor
In an attempt to increase battery life further I’ve now got the HTU21D humidity and temperature sensor powered by a digital pin from the ATMega328p. In code the sensor is […]
Sensor Node Progress
I’ve made some great progress with the sensor node project over the last two days. After finally getting around the problems I was having with the software bugs and the […]
RFM69CW – Never ending issues
I have no idea why but my experiments with the RFM69CW have descended into chaos and frustration. At first I had the units talking to each other and sending out […]
New Electronics Lab Build
So the build of my new Electronics lab/workshop/home office has begun. I’m starting completely from scratch and building a complete wrap around curved desk that covers 3.5 walls in a […]
