AVR Mini Board With Additional Boards

AVR Mini Board With Additional Boards

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.Using attiny2313. Step 1: Scheme Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller.

Model Train Speedometer V2

Model Train Speedometer V2

This project started off being based on an Arduino UNO. And it worded ok, I found the software published on the internet. For example https://forum.arduino.cc/t/model-railroad-speedome… This is actually version 2 using a smaller PCB and PIC chip. It works in exactly the same way as V1. I wanted to make the device smaller, neater and if

7 Segment Pov 16F84

7 Segment Pov 16F84

This is a post about the POV ( Persistence of Vision ) Display that uses one 7 Segment display. In short, I made this little project as a proof of concept of something I ‘ve always noticed in many electronic devices those used 7 segment display. Devices like 7 segment display clocks and meters. In those devices, the 7 segment

8 Bit Serial Digital to Analog 5v Range Converter for Microcontrollers when TTL and Resistors Is All Youve Got

8 Bit Serial Digital to Analog (5v Range) Converter for Microcontrollers (when TTL and Resistors Is All You’ve Got)

So I needed a DAC (digital to analog converter) to use with my pic12F675 , and for those of you who have never heard of this little fella, it’s an 8 pin microcontroller from Microchip that has only 6 I/O pins… This is a very simple circuit that converts Digital data (serial input) to Analog

RGB LED Love Heart

RGB LED Love Heart

This project creates a RGB LED lit love heart which is controlled by a PIC12F683 microcontroller.  I designed the project as a gift for my wife on our 15th wedding anniversary (since she puts up with my addiction to electronics I thought she deserved something in return!). The love heart is made from a 200x150x6mm
