Pin numbers used to program a chip on the Arduino IDE are based on how the chip manufacturer has internally named/aranged the pins . The manufacturer of the ATtiny85 is ATMEL (the AT inATtiny85-actually stands
In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many showing a serial LCD and on my Arduino the PINS to attach the UART pins are hid...
Well you generally don’t but since we can connect up to 128 devices (7 bit Address system) on the same I2C line and let’s say we want to connect two different LCDs on the same I2C line, than we can’t use two PCF8574 with same addresses and we need to modify one of them. So...
Stand (Cradle)- The iron stand (often referred to as a cradle) is what houses the iron when it is not in use. The stand may seem trivial, but leaving an unattended iron laying around on your desk or workbench is a potential hazard: it could burn you, or, worse, it could burn your...
Write to the Display in 8 Bit Mode Let’s start with a simple program that will display “Hello world!” on the LCD. If you have a different sized LCD than the 16×2 I’m using (like a 20×4), change the number of columns and rows in line 2 of the code.cols=sets the number...
In addition to CEC Firmware, any firmware can connect SDR in the following way. If you are not using CEC Firmware version 1.070 or later, you need to modify the source code a little bit because RTL-SDR can only receive more than 24Mhz. Also, there are a lot of better ways than I ...
The Arduino IDE has a built-in library (LiquidCrystal.h) that supports LCDs based on the Hitachi HD44780 chipset (and/or ones that are compatible with it). Other than displaying text on an LCD, the library can also handle printing floating point numbers to a specified amount of decimal pla...
