I’m working on an IoT-embedded device with various air quality sensors (CO2, CO, NO, SO2) that connect to the internet using WiFi, GSM, or Ethernet. The device is designed to […]
Hi, I’m building a weather station using Arduino to measure temperature, humidity, and atmospheric pressure. Now, I want to take it a step further and establish IoT connectivity to transmit […]
Based on my previous question, How do I enroll fingerprints into the sensor and store them for future comparison? cause am getting an imaging error and error receiving packets when […]
Hello, I am trying to interface a BME280 sensor with a Raspberry Pi Pico using MicroPython over I2C to monitor environmental conditions such as temperature, humidity, and pressure. However, I […]
Hi there, right now I am planning to make a device which can detect a heart attack by using MAX30102 After a small research, I found out that a heart […]
Hello, all. I am doing a project in which I need to measure DC voltage up to 40V. I know that I could do a simple voltmeter using 2 resistors […]
hello devs, still based on my project parking assistance system using a BeagleBone Black running Embedded Linux, VL53L0X time of flight distance sensor to detect the distance to nearby objects […]
Hi everyone, I am trying to rebuild a device and have wired everything according to the schematic: You can see that the output pin of the photodiode (pin 5) is […]
My latest WIP, the “World’s Second Smallest MIDI Controller” (I think). It’s a bit bigger than the first iteration https://www.youtube.com/watch?v=5Ws_JfCw5NY in order to accommodate a potentiometer and larger buttons, as […]
