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...
They cost less than 1 cent each, but humble resistors are an essential tool no matter what electronics you are building. In this reference guide we look at using them in projects, and how to identify the correct resistor for your project.
There are different ways of connecting a push-button to the Arduino board: You can connect to a power source and ground (GND), then specify if the push-button will be a pull-up or pull-down input. You can use a resistor to connect the push-button as either pull-up or pull-down. ...

of a USB to TTL 3V3 Serial Cable, it is also possible to program the ESP-01 using an Arduino UNO, usingthis circuit, but don't use the UNO 3V3 power pin as the ESP-01's power supply it is only rated at 150mA and can cause problems when trying to debug a project that uses ...
This board has a 3.3V regulator enable pin with a pull-up resistor. This pin is connected to a push-button on the ESP32 board. Therefore, to automatically restart the board, connected this pin to the ground permanently. If you liked this tutorial, you may also like to check these tutori...
How to Program a AVR (arduino) With Another Arduino: This instructables is usefull if: * you've got your arduino with atmega168 and you bought an atmega328 at you local electronics store. It doesn't have an arduino bootloader * you want to make a proje
In this Arduino tutorial we will learn how to use the HC-12 wireless serial communication module which is capable of making a long range wireless communication between multiple Arduino boards, with distances up to 1.8km. For this tutorial I made two basi
One huge advantage of the grblShield with the Arduino is the ability to use a regular old USB connection. Welcome to the 21stcentury. I know don’t fall out of your chairs. My harbor fright mini mill isn’t all that big. I really didn’t want the controller to be bigger than the ...
