Manchester for Arduino

There are several Manchester Coding libraries for Arduino wireless transfer (See http://tinyurl.com/jh95cju), I have gotten two of them to work satisfactorily for communicating a single byte of data. Both the “Mchr3k” library “http://mchr3k.github.io/arduino-libs-manchester/” and cano64’s library “https://github.com/cano64/ManchesterRF” worked for singly … Continue reading

STX-882 / SRX-882 Radio Testing

I recently did some testing of the STX-882 433HHz transmitter and the SRX-882 433MHz receiver and, after additional tests, updated my original findings. I tested line-of-sight along a road. I performed two tests using Arduino NANOs and two laptops, shown … Continue reading

An inexpensive Software Enabled Pseudo-Transceiver for Arduino

Recently I taught a brief, three hour long, Arduino 101 course to some fellow members of the Western North Carolina Linux Users Group (WNCLUG). One of the three lessons in the course was for the students to pair off and … Continue reading

Programming the ATTINY85-20SUR

This post ties together my two previous posts, “ATtiny85 SOIC chip Program Adapter” and “Universal programmer dusted off“. I inserted the ATTINY85-20SUR nested in the SOIC Adapter Socket OTS-20-1.27-01,  plugged it into my DIY Universal Programmer socket and connected it up to my USBasp programmer. … Continue reading

ATtiny85 SOIC chip Program Adapter

When I purchased some surface mount ATtiny85 microcontrollers I didn’t realize that Atmel sold them in several widths, so I purchased the incorrect size SOIC programming adapter that would have enabled me to program the chip prior to soldering it … Continue reading

Universal programmer dusted off

Lately, I have increased my microprocessor/gadget activity after a hiatus/slow down. A project that I have been (slowly) working on was developed and debugged on an Arduino NANO but the final target is a surface mounted SOIC ATtiny85-20SUR operating at 3-Volts. … Continue reading

Progress Report – Hall Transistor based Level Measure

Below you will find a progress report video. The video shows a demonstration of my work-in-progress project that I have mentioned, at least the 3D Print portion, in previous posts. The actual product is a powder level alerting system used in … Continue reading

SMS from Arduino

A few weeks ago I was chatting with my mail carrier who is also a beekeeper. I mean LOTS of bees with some hives in remote locations. He has a friend that is working on a system that weighs hives and … Continue reading

A Revisit of the PT2262 PT2272 with Arduino and r06a Receiver

A year ago, on July 19th, reader Jeff posted that he had an inexpensive Chinese motion detectors that used the 2262 chipset. He was having some trouble getting it working with the r06a receiver as in my July 2012 post … Continue reading

SD Card Module and Temperature Sensor

I recently tested two new modules that I received from Chinese suppliers: a SD Card Module made by LC Technology (www. lctech-inc.com) and a DHT-11 Temp & Humidity sensor. My test makes 25 temperature/humidity readings (inside my house) and writes them … Continue reading
