This tutorial shows how to control your ESP32 or ESP8266 boards through a Telegram group. Using a Telegram group to control your boards may be useful if you want to have several people interacting with a bot on the same chat and you want all those people to get notifications from the bot...
LED light blink.1. Experience the programming steps of Mind+ 2.Learn sequential structure and loop structure In Project I, we learned how to light up the UNO onboard LED light, and then we will learn how to control an external LED light.1.Learn variables and constants ...
This sketch prints sequential numbers on theSerial Monitor: /* * SerialOutput sketch * Print numbers to the serial port */ void setup() { Serial.begin(9600); // send and receive at 9600 baud } int number = 0; void loop() { Serial.print("The number is "); Serial.println(number);...
The last line declares a NeoPixelobject.We’ll refer to this by name later to control the strip of pixels. There are three parameters orargumentsin parenthesis: The number of sequential NeoPixels in the strip. In the example this is set to LED_COUNT, which was defined as 60 above, equal...
As you develop and modify a sketch, you will want a way to keep track of changes. The easiest way to do this is to use the Git version control system(see thisAtlassian Git Tutorial pagefor installation information). Git is typically accessed using a command-line interface (there are graphi...
Pin 9 is used by the TMRpcm library for playing back tones, so this interrupts our sequential 2-9 keypad pin layout. Also pins 10-13 are being used by the SD card shield which leaves us with no extra pins to finish our button and last keypad pins on the right side of the board. ...

After I use the example code, I cannot even control the BUILTIN_LED. I want to use ArduCAM to connect both OV5642 and L298N, is there any way to know how to setup the pin? You mentioned "change them as general IO". Does it mean, if I want to connect to multiple components, I...
LED and GPIO_LDD: Driver for the RGB LED on the Freedom board (see this tutorial). Note that the signal for the blue RGB LED is used for the SD card SPI clock signal by the Data Logger Shield. BitIO_LDD: Used for the green and red LED on the shield (see this tutorial). The ...
