The line of code starting with ‘pinMode’ sets pin 13 as an output. This enables us to write a value to the pin. The value can be ‘HIGH’ or ‘LOW’. HIGH turns the pin on and LOW turns it off. Therefore, to turn on pin 13, we need to write ‘HIGH’ to it as shown on...
Configure Read and Write for GPIO Pins You can use the Pin Explorer pane and Pin Configuration panel in the Arduino Explorer app to configure each pin to read and write data. In the Pin Explorer pane, click the row corresponding to the pin that you want to configure. The Pin Configuration...
- BLUE AND WHITE Product ID: 772 This new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the Blue & White 16x2 LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to ...
