A tone-synthesizing STM32F407 audio player with FreeRTOS multitasking, I2S DMA streaming, pot volume, and LCD status feedback.
Transform an RT-Spark board into an MP3 player using FreeRTOS to concurrently manage audio playback, LCD updates, and hardware inputs.
Draw a schematic, get a breadboard: components placed, wires routed, and a step-by-step guide to build it.
A low-cost ESP32 IoT system that monitors poultry water temperature in real time on a 20,000-bird farm, sending alerts and reducing producti
Quickly explore a variety of op amp configurations on a small PCB with solderless component headers, supply rails and a signal generator.
Experiments with the STM32 microcontroller with 5 switch controls to activate 3 LEDs in active low and in-built LCDs by RT-Spark
A simple Arduino UNO project demonstrating how to control and blink an RGB LED using basic electronics and programming.
A reaction-time measurement device built on the RT-Spark development board that uses hardware interrupts to record precisely.
An Arduino-based distance indicator that uses an HC-SR04 ultrasonic sensor and colorful LEDs to visualize object distance in real time.
74LS04N is a classic six-channel TTL hex inverter. This project use it with an Arduino Nano to create a simple 5V digital signal laboratory.
What I learned Today? Used 555 IC, LED, 330, 47k, 10k resistor and 47uf, 0.01uf capacitor and 9v battery for a flash blinker 1st project.
