Arduino USB: 5 Steps - instructablescom
Did you know it is possible to toggle the state of a Arduino OUTPUT pin using a single line of code? It’s true! It’s also possible to use digitalRead() on an OUTPUT pin. Arduino: Toggling Outputs by James Lewis. figures out with Port and Bit to change, and writes to it. That is …
Arduino Interface PCA9555 GPIO Expander With Code
I2C Port expanders - 8574, 8574A, 8575, 9555 etc. If you just don't have enough digital I/O pins on your Arduino to interface with all your sensors and controls, you might want to look at using the I2C bus to connect a few port expander chips:

Using the 8x32 LED Matrix To Create a Mobile, Wirelessly Controlled Display These 8x8 LED units have a controller that allows an Arduino to talk to them sending text or graphic information that can be displayed. These small units can be daisy-chained together to create a long, scrolling display. Invert display - enter /i

Find the I2C port on which the SSD1306 screen is connected. Before you can use the SSD1306 OLED screen, you will have to configure the port on which it is located. For this, Nick Gammon’s has developed a small Arduino program to find the I2C port on which is connected the OLED screen.
Ready, Set, Oscillate! The Fastest Way to Change Arduino
Arduino Digital Pins HIGH LOW output seem to be reversed. I've tried the BLINK EXAMPLE and in that case also the output seem to be reversed. I have tried this on three different arduino uno boards, tried with different sensors but the HIGH-LOW seems to be reversed. android bluetooth arduino arduino-ide digital-logic. share
