Control a servo motor from up to 1 kilometer away! 📶 Wiring it up This circuit is based on two separate Arduino circuits; we will consider one of them a transmitter and the other as a receiver. You must follow the following instructions in wiring the two circuits to control the servo motor to open and close the door from a distance: The transmitter circuit: Connections from the Arduino to the breadboard: • Arduino GND pin → Breadboard ground line • Arduino 5V pin → Breadboard 5V line Connections from the HC-12 module: • GND pin→ Breadboard ground line •...

Control an LED from anywhere via your phone!📲 Wiring it up Before you begin wiring the shield with your Arduino, let's learn about the SIM900 GSM shield and setup it so that it works properly with you. The following image shows the most important components of the SIM900 GSM shield. Understanding the different parts of the shield will let you understand this tutorial much better. You will also need a 5V/2A DC adapter to supply the shield with the necessary power through the DC jack. You must check the specifications of the adapter well. Also, remember to insert the SIM...

Read a TXT file from SD card Wiring it up To set up the SD card reader in the correct way, follow the instructions below. The image demonstrates how to connect the wires between the SD card reader and the Arduino. Once the SD card reader and the Arduino are connected to each other, connect the Arduino to your computer using the USB cable. Connections from the Arduino SD card module: • Arduino GND pin → SD card module GND pin (- pin) • Arduino 5V pin → SD card module VCC pin (+pin) • Arduino pin 12 → SD...
