Based on your environment and technical requirements, choose the best device to complete your project. Make sure you device is transmitting data through RS485. Our project calls for a Arduino UNO using a RS485 shield with an humidity sensor to transmit...
Here I will read the analog port and look for a high signal. And switch the pins accordingly. I have written everything in comments and code is self-explanatory. Whenever it reads a certain voltage at analog pin it activates the switch. This switch can...
Now all you need to do is open the telegram app open the bot after searching it in the Telegram App by the name you gave to the bot. As you open the bot you will see a Start/Restart button click on that button the bot will start and send you a list of...
Embedded computing is basically computing integrated to the real world, and the real world is pretty much analog. By default, electrically measuring analog real world values produces analog voltage or current (which can be converted to voltage using...

I made a status indicator that notifies me of my body's relative state of arousal! To help me visualize what's going on with the myriad of wearables I have set out to don at once, I've created an arm-mounted screen display that will tell me what I need...
Open main\bt_app_av.c Replace the function void bt_app_a2d_data_cb(const uint8_t *data, uint32_t len) with the following code: void bt_app_a2d_data_cb(const uint8_t *data, uint32_t len) { size_t bytes_written; uint8_t *mydat = malloc(len); if(mydat ==...
1. Create a new Zerynth Project. To do this, press Browser Project > New Project then assign the project title and the project folder. To finish, press "Create". 2. Next, your new Zerynth Project will automatically open to the "main.py" file....
Determine the Maximum Output ValueFirst let's see what range our output falls into. The following Arduino code will show the maximum and current value of the measurement from the shield on the serial monitor. Load this in your Arduino IDE, run it and...
Explanation circuitThe circuit has two main parts, the transimpedance amplifier and resistors settings RGB LED:Transimpedance amplifierThis circuit serves to convert the intensity of the photodiode into a voltage and amplifying the signal of this, the...
