Circuit Diagram for this Arduino Alcohol Sensor Project is given above ... Now we just need to attach LCD to the Shield and place this Alcohol Detector Shield over the Arduino. Align the Pins of this ...

I set about making a LCD Shield to go on top of a standard Arduino. The circuit uses a 16x2 LCD with the common 44780 chipset. To save on pins this is then run through a 4094 8-Bit Shift Register.

By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, ...

Simple shield to connect an HD44780-compatible, 16x2 LCD module to an Arduino or compatible such as a Freetronics TwentyTen. Features: Reset button connected to ...

Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive backpacks to interface with a microcontroller in ...

That said, this shield ... an LCD and four-button interface to fiddle with settings, and is based around an LT1510 constant current/constant voltage charger IC. You can find the schematic ...

The bill of materials is detailed in the table on previous page. Fig. 1 shows the circuit diagram of the proposed drain shield for smart cities. It is built around an Arduino Uno board (MOD1), GSM ...

I had a few problems with the PWM part mainly because the fan made a disturbing noise so I had to add a simple RC filter at the output of the PWM pin on the Arduino board. I used an LCD shield to ...
