Here’s the Arduino Code for this example. It’s quite simple. We just need to define the PIR Sensor pin as input and the relay pin as output. Using the digitalRead() function we will read the output of the sensor and if its high or if an object is detected it will activate the r...

ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE Strapping GPIO Pins Some GPIO pins are used to configure bootloader or flashing mode of ESP32 during application flashing or bootloading. GPIO0 GPIO2 GPIO4 GPIO5 (must be HIGH during boot) GPIO12 (must be LOW during boot) GPIO...
Arduino is mainly used to build electronic projects for everyone – electricians, tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, ...
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...
Keypads are a great way to let users interact with your project. You can use them to navigate menus, enter passwords, and control games and robots. In this tutorial, I’ll show you how to setup a keypad on theArduino. First I’ll explain how the Arduino detects key presses, then I’...
Using a web interface you can send commands to your Raspberry Pi and either use the GPIO on the Pi use those commands to interface to your Arduino via USB cable. You can use a secure tunnel or VPN to control it from anywhere in the world with this method (not just your local Wifi ne...
In this Raspberry Pi pressure pad tutorial, I will go through the steps of connecting a force sensitive resistor to the Pi. There are many uses for a pressure pad, such as detecting when someone sits down or places pressure on a specific part of an object. It is a pretty great sensor ...
When the intensity of the light is at maximum level the voltage output will be reach maximum. You can replace the R1 with a Pot to adjust the sensitivity of the sensor.These type of sensors are used in Analog applications where the output voltage is proportional to the incident light on ...
The Blynk app lets you create aGraphical User Interface (GUI) for your smart kitchen IoT. Therefore, you will get to see a visual representation of all your sensors, along with their readings in real-time. Moreover, you will also be able to control all electrical kitchen appliances that yo...
