This is a new section (2019) and it will contain various projects I make, this will often be test equipment of some type, but can also be useful Arduino libraries, some notes or something I make just for fun. Some of the projects will include everything to duplicate them (Software, schematic, PCB layout, gerber files, manual, etc.), other will just show what I made, but without detailed information. I do not expect to post new projects very often.
7 & 14 segment display modules specifications
This is a list with measurement of all the 7 & 14 segment displays I have used to make my library. It is sortable and contains filters.
ADS1115 ADC library
This library allows use of any speed and gain of the ADS1115 while running it in the background. It can also do auto ranging conversion.
Display driver library for 7 segment LED and LCD displays on Arduino
This is a "library" that basically supports all the cheap serial 7 segments display found on Ebay, both display, indicators and keys.
Computer controlled logic outputs
This is a 3.3/5V driver can be controlled from a computer to turn on/off, do PWM or pulses of various types, including LED control (NeoPixel). The project includes full schematic, software, manual, etc.
Computer controlled solid state relay
This is 3 isolated mosfet transistors that can be controlled from a computer to turn on/off, do PWM or pulses of various types. The project includes full schematic, software, manual, etc.
Building a high current adapter
This is a fairly old project I have moved from "Anything else" to here. It is a very low voltage drop current "shunt".
