Sheld for Arduino with an H-bridge L293D which allows to drive two DC motors
Prototype of the shield
New version [New version] with there is an integrated 74LS06 in which are present within six logical NOT gates (inverters).
Two of these are used to invert the logic value present on the input. In this way it is possible to reduce the number of ports required to dr...
copy from that site and added extra 3 more lamps to work on.
MySensors Standard Board
Arduino Pro Mini + NRF24L01+
2 Sensor inputs
10 pin expansion header for connecting an expansion board(to be made)
The expansion board will have 4 extra digital inputs/outputs and 2 Analog inputs
## Arduino drives 5 button keyboard ##
5 button keyboard: the use of series resistor and switch to determine the various voltage to be sent to a Arduino analog input.You can use the same technology to install multiple buttons in other ways or directions.
## 5 button keyboards CODE ##
#define keyboard_AnalogInput 5
#define btRIGHT 0
#define btUP 1
## Arduino drives I2C LCD Controller based on a LCD1602 module ##
## LCD Software Library Information ##
ALL the displays will use the IMPORTANT Library written by Francisco Malpartida.You can download the Library:
[the great Library ]
you must have the library installed correctly.
And Check the small backpack interface board on the back. These small boards on the back inter...
This is a schematic for the notifications buzzer I've created in the video below.
[Realtime Event Notifications Using NodeMCU (Arduino), Google Firebase and Laravel]
In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert.
The board is programmed with the Arduino softwar...
