Complete Arduino code is given at the end of this Article. In the programming part of this project, we have used two Arduino pins, one for generating block waves to be fed in Coil and second analog ...
Circuit Diagram for this Arduino Alcohol Sensor Project is given above. We have a comparator circuit for comparing output voltage of Alcohol Sensor with preset voltage (output connected at pin D7).
Using a circuit simulator can get you part of the way and software simulators abound. But cosimulation — simulating both analog circuits and a running processor — is often only found in high ...
Connect the 2N2222 transistor to the pin3 of the Arduino with a resistor connected to the base of the transistor and collector terminal to the 5V of Arduino Uno. Connect a small bulb between the ...
The Arduino puts 5V on the relay pin. → The relay goes on. (Now you can take away your finger from the button) If the Arduino senses water between the two pins → It puts 0V on the relay pin. → The ...
Pin Headers S3, S4: Pin headers that provide access to the digital, analog, and power pins of the Arduino Nano for connecting sensors, actuators, and other external components. ICSP (In-Circuit Serial ...
You can understand the main working of this sensor by the following diagram. This sensor has two pins, trigger pin, and eco pin that are both used to measure the distance between two particular points ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.
At The Conversation, we take table tennis very seriously. After setting up a new ping pong table, and wanting to learn how to use an Arduino, I had a bit of time to build a scoreboard. An Arduino ...
