Just sharing a quick update on the bicycle odometer project, I have assembled and tested the PCB, now to the bicycle itself
An update on the bicycle odometer project, I started tinkering with the ESP8266MOD power consumption a bit. Such a pain
I started coding for my Bicycle speedometer with ESP12. The idea of the code is to light a single LED…
The HW-006 optical line tracker sensor is an optical assembly used to track lines, mainly for small competition vehicles
We will see how to control the hobby servo motor SG90 with ESP32-C6, by using a library called Servo.h. Simple way of controlling a servo
I will show you how to get using the ESP32-C6 with CircuitPython, flashing the bin file to make it work. We will use an Espressif software
We will learn how to use the Ws2812b addressable RGB LED with ESP32-C6, a light emitting diode chip which can do many RGB colors
Let’s implement code for the encoder ky-040 soft library – without interrupts, just an if that enters the reading every 5ms
Let’s do a LED display clock and thermometer with DS1307 and TM1637 (a RTC real time clock and a 4-digit LED display) with Arduino UNO
We are going to get to know the real time clock RTC DS1307 chip with Arduino code, adjusting and reading time and date
We are going to study the GC9A01A round LCD 240×240 display, a neat little round color display programmable with Arduino
A list of the top 10 most read FritzenLab articles, containing the ten articles most viewed and read in June of 2024
I made a bench power supply featuring variable voltage (4.5-12V at 5A), fixed 3.3V and 5V at 3A each. All of it using cheap modules.
We are going to study the technology of Soil moisture sensing using ESP32-S2 and sending data to Thingspeak
Today we are going to dive into the technology of OLED display with Arduino, trying out two libraries and settling for one with Arduino UNO
Another update for you on the bicycle odometer project, showing that I have finished the schematic and routing the PCB
A quick update on the bicycle odometer project, to show you that I have finished the schematic and done a tentative PCB design
Update one of the bicycle speedometer project, an instrument used to measure speed of a bicycle using a single reed switch sensor
Let’s talk about the RCWL-0516 microwave radar sensor, a human-presence detector sensor using microwaves. Simple Arduino interface (one wire)
We are discussing how to use the PIR motion sensor, a infrared human motion sensor with Arduino, using a single digital input
