Arduino control Servo Motor via BluetoothIn this tutorial, we will learn how to program an Arduino to control a Servo Motor using either Bluetooth (HC-05 module) or BLE (HM-10 module). Instructions for both modules are provided.We will use the Bluetooth Serial Monitor App on smartphone to ...
For example, you can replace those LEDs with a relay to control your house appliances. Associate a button to turn off or turn on all the LEDs at the same time, etc. This can be particularly useful because some remotes have a bunch of buttons that you never use. So, why not use them...
This is the Non-Latching Mini Relay FeatherWing. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board. Using our Feather Stacking...
Code for Using a Button to Control a Relay The following code will allow you to use a button to control a relay with the Arduino. // constants won't change const int BUTTON_PIN = 7; // Connect the Button to pin 7 or change here const int RELAY_PIN = 3; // Connect the LED to...

Connect one of the button pins to pin 11 through a ~ 5 kOhm resistor, and the other pin to ground (GND). Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp)...
Sketches: These are Arduino programs that are written in the IDE. They use the Arduino libraries and can be used to control the board's behavior based on the inputs and outputs defined. Arduino IDE Download For every Arduino-supported you might need Arduino IDE to upload the code, for...
The “ESP32 IoT Relay Board” is a credit card-sized ESP32 board with four small 250VAC/30VDC 7A relays that runs Tasmota open-source firmware and supports Alexa & Google Assistant for voice control. There are so many ESP32-based relay boards on the market that I don’t usually feel ...
