    Notes
    What happens is that the contacts on the harness loosen over the years. The connectors also oxidize and start making bad connection with the board. As the resistance to the current goes up, so does the heat which burns up the connector.

    Notes
    Artisan is a software that helps coffee roasters record, analyze, and control roast profiles. When used in conjunction with a thermocouple data logger or a proportional–integral–derivative controller (PID controller), this software can automate the creation of roasting metrics to help make decisions that influence the final coffee flavor.

  • Understand How It Works - Martin Rue
    Notes
    If you simply remember how to do something, then all you can do is use it the same way over and over, but if you understand how it works, you can reason about it. Once you can reason about something in your mind you can contemplate why it is the way it is, you can apply your entire creative mind to making the most of it, and you can implement and question improvement – you own it intellectually.

    Notes
    The SPI (Serial Peripheral Interface) is a peripheral used to communicate between the AVR and other devices, like others AVRs, external EEPROMs, DACs, ADCs, etc. With this interface, you have one Master device which initiates and controls the communication, and one or more slaves who receive and transmit to the Master.

  • Wiring the Cobbler to the LCD | Drive a 16x2 LCD with the Raspberry Pi | Adafruit Learning System
    Notes
    Whenever you come across a LCD that looks like it has 16 connectors it is most likely using a HD44780 controller. These devices provide the same pinouts making them relatively easy to work with. The LCD uses a parallel interface meaning that we will need many pins from our raspberry pi to control it. In this tutorial we will use 4 data pins (4-bit mode) and two control pins.

  • 3-Wire Serial LCD using a Shift Register
    Notes
    HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip. The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins.
