Arduino Pin Turns On Transistor >> Transistor Turns On Relay >> Relay Connects Appliance To 120V Power Outlet.With that out of the way, you should also use a resistor to connect your Arduino to the transistor. This prevents the transistor from drawing excessive amounts of current and burning...
So, as I already said, this RC airplane is entirely based on the Arduino, both theTransmitterand theReceiverare custom builds based on the Arduino Pro Mini board. I already have detailed tutorials how to build and how the transmitter and the receiver work, so you can check them out for m...
Here we also have the eyes of the ant which are design to fit an HC-SR04 ultrasonic sensor. All of the parts are assembled between two plates and additionally I made an interesting curved cover for the top plate in order to hide all of the wiring, the Arduino and the battery between t...
The output signal, again, comes from pin 5 of the LM386 IC. The positive terminal (+) goes into an analog terminal of the Arduino; we will connect it, in our case, to A0 of the analog terminal. The negative terminal (-) connects to GND on the arduino. This allows us to process ...
Connecting Motor Driver to Arduino UNO Pin number 1 and 9 are the enable pins, we connect these two pins to a 5v input to enable the motor. Pin number 1A, 2A, 3A, and 4A are the control pins. For eg. The motor will turn to the right if the pin 1A goes low and 2A goes high...

There are no circuit connections required to build this project. Simply fit the TFT touchscreen shield on Arduino UNO or Arduino Mega, powering the board via a USB or power adapter. You’ll also need to connect Arduino to your computer using a USB cable to upload the sketch. ...
Current=(AcsOffset - (analog reading measured by Arduino)/sensitivity When no current flows through the circuit, Acs Offset is the normal voltage output on the Viout pin. The analog reading measured by ALLEGRO is an analog signal value, which is read from the analog channel connected to the...
Electronic devices you build with Arduino start to become very cool when you connect them to the network.Let’s see how to connect an Arduino to a WiFi network.The Arduino must have WiFi connectivity, for example the Arduino MKR WiFi 1010, which is the one I use, or the Arduino Uno ...
In this project, we are going to measure the value of AC current with the help of a Current Transformer (CT) and Arduino. The system also includes a rectifier and amplifier circuit for signal conditioning.
