The MQ-4 is one of many gas sensors ready to be interfaced with microcontrollers Just like the rest of the MQ sensors, the MQ-4 is most sensitive to a particular gas This time,...
The BH1750 is a light-intensity sensor that interfaces with a microcontroller through the I2C bus It can directly provide lux values without further processing, unlike CdS cells...
How can you create sine, square or triangular waves with Arduino Apparently, there’s a way with the help of an IC package -- the AD9833 With it, you can now create waveforms for...
I2C is a popular device protocol in communicating with microcontrollers However, this protocol is not limited to Arduino, PIC and STM32; the Raspberry Pi can also use I2C ...
In Arduino programming, we learn about functions setup() and loop() Any code inside setup() executes once while code inside loop() executes again and again until the next...
This project makes the “dots” on a dot matrix look like they are pebbles in a container Tilt the device on one side and the dots fall toward that side The same goes if the...
A seven segment display has one pin for each of its seven segments This means if directly interfaced with a microcontroller, you will need at least seven pins Fortunately, there...
Measuring an object’s weight can sometimes be part of a bigger project And unless you have a good reason, you wouldn’t want to use an analog weighing scale A digital weight...
This ESP32-powered project allows you to write messages to a MAX7219 LED matrix display using your smartphone Scaled up, this can be used as a WiFi message board for schools or...
