As we mentioned earlier, BH1750 ambient light sensor can be interfaced with Arduino through I2C bus pins such as SDA and SCL that are A4 and A5 pins of Arduino Uno. This schematic diagram shows the internal circuit of the breakout board: Connection with Arduino Uno To interface, this light...
The IR sensor module also consists of other components such as anIR emitter LEDwhich emits the infrared light, anIR receiver LEDwhich receives the light after the collision with any object, apower LEDwhich turns on when this sensor is powered up,distance adjuster, through this, the user can ea...
Connect the VCC and GND of the module to the 5V and GND pins of the Arduino. Then connect the DATA pin to Arduino’s digital pin 2. We communicate with DHT22 through this pin. Arduino DHT22 Code for Interfacing the Sensor Module Now let’s look at the code for interfacing the DHT22...
Arduino. The rain sensor module is an easy tool for rain detection. It operates as a switch when raindrop falls through the raining board and also it measures rainfall intensity. The module features, a rain sensing board and the control board that is separate for more convenience, power indic...
Arduino with Transistors For the first couple of experiments, we will use the TIP120 power Darlington BJT. You can substitute a BJT with similar specifications if you don’t have a TIP120. I’ll be using 6-volt batteries and loads for my experiments, but you can use any DC power source...
SMP: handle sensor+servo on different core than the web server. stop using GET requests and move to a streaming protocol. Fork the repo Make a branch with a sensible nraeme in your forked repo and commit changes to that Make a PR in this repo against your remote fork and branch ...
