This instructable shows how to get the most out the limited pins available on the ESP-01. Using GPIO0 / GPIO2 as an I2C bus gives the biggest expansion, but if you project does not use I2C, you can still drive a
The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general-...
Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this ...
As the term suggests, a smart kitchen is a kitchen where many kitchen appliances turn on automatically. Moreover, you can also control them remotely as well. However, unlike the ecosystems forGoogle Home devicesand Amazon Home devices, there’s no smart kitchen ecosystem in the market yet. Ho...
These were then connected to the S.Port pins on the MLVSS sensor in the normal way (and obviously I put new heatshrink back on the ESCs). As mentioned BLHeli_32 was originally intended for quads but it's highly configurable and can be used for fixed-wing, boats, cars, etc. There's...
IoT is a vast topic, and there are many ways you could approach it. Find an area that you are passionate about. It is best if it relates to a problem you are currently facing and you use it as an opportunity to learn new skills. It is an exciting journey, and you don’t have to...
If you have any questions about how to set up the DHT11 humidity and temperature sensor on your Arduino, just leave a comment below and I will try to answer it… And if you like our tutorials, please subscribe! Also, feel free to share this if you know anyone else that might find it...
Hi, How is it possible to light sleep with arduino framework on the ESP8266, i know how to deepsleep and it works but i am interested to do LIGHT_SLEEP so i can benefit from "low power" equal to 0.5mA and have GPIO wake up enabled with g...
Then, for the setup, we initialize the serial monitor at 115200 to create prompts and display information. Moreover, using begin functions, we connect to the WiFi, start a server then initialize the DHT sensor and time server. void setup() { ...
lcd = CharLCD(cols=16, rows=2, pin_rs=37, pin_e=35, pins_data=[33, 31, 29, 23]) while True: lcd.write_string(u"Hello world!") time.sleep(1) lcd.clear() time.sleep(1) Press Ctrl-C to exit the program. Turn the Cursor On and Off ...
