If you’re looking to learn how to make your own electronic devices at home, it’s important to understand that you’re going to need two things: a microprocessor and the...
The 8051 microcontroller is much older than the ones featured here Yes, even older than the PIC16F84A However, being flooded by messages from students about this microcontroller...
I recently bought a mini Arduino water pump that runs on 3 to 6 V Since it consumes very little current (130 mA @ 3V according to its specs), it seems perfect to be used for small...
Now that you've set up your WeMos D1 Mini to be programmable using the Arduino IDE, it's time to build a project I'm a huge believer in active learning and project-making does...
If you've been following my tutorials on ESP32, then you'll notice that the WiFi SSID and password are always hardcoded This tutorial will show you a way to change the WiFi...
With its WiFi capabilities, the ESP32 can connect to API services and acquire useful (and sometimes useless) information from the web Here’s a quick tutorial on how to connect...
Arduino is easy to use but that's at the expense of numerous features, the most glaring of them is speed Hence you would rarely see an Arduino in an embedded, industrial setting...
A finite state machine (FSM) is a theoretical machine that only has one action or state at a time The machine may go from one state to another if there are inputs (or one input)...
