8×8 RGB Led Matrix with WS2812 driver with Arduino Uno
https://www.electronics-lab.com/8x8-rgb-led-matrix-with-ws2812-driver-with-arduino-uno/
In this video we learn how to use this 8×8 RGB LED matrix. This matrix is using the WS2812 driver and it is great, because each LED is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. 8×8 RGB Led Matrix with […]

ATtiny85 Ring Watch
https://www.electronics-lab.com/attiny85-ring-watch/
This is a great ATtiny85 watch that uses a SSD1306 OLED display and is powered by a CR1220 battery. Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to 2.0 V, so this […]

https://www.electronics-lab.com/mc9rs08kb4cfk-minibot/
The Minibot is a small autonomous robot vehicle that uses phototransistor that can detect lightness patterns on the ground to follow the edges of the dark lines. It has a MC9RS08KB4 MCU, coin cell, motor, and a phototransistor. The MC9RS08KB4 is part of the MC9RS08KB12 series, a family of RS08KB 8-bit microcontrollers. It features a […]
Datalogging Accelerometer Data To An SDCard
https://www.electronics-lab.com/datalogging-accelerometer-data-to-an-sdcard/
MindForge @ 43oh.com build a datalogger board which logs accelerometer values on a SD Card. The datalogger is built around an MSP430G2755 microcontroller and ADXL335 accelerometer sensor from Analog Devices. his project started as an EMG datalogger to study my dad’s Parkinson’s disease, but after some testing I determined wearing electrodes wasn’t practical for the long term […]

https://www.electronics-lab.com/kinetis-kea128-startertrak-for-can-applications/
This reference design is a low-cost development kit based on Kinetis EA series MCUs that allows faster prototyping and tool reuse. This evaluation board features either one of the KEA128, KEA64 or KEA8 MCUs, depending on the board version. This particular design uses KEA128. The Kinetis EA series MCUs are a highly scalable portfolio of […]
ATMEGA328 Component Tester
https://www.electronics-lab.com/component-tester-2/
baweja_akshay @ instructables.com has build a ATMEGA328 component tester that is able to test Resistors, Capacitors, Inductors, BJT, FET, Thyristors and more. Coming upon COMPONENT TESTER so it can test almost everything, obviously not the power components because they require more current and power which our AVR Microcontroller couldn’t handle !! Oh yeah, I forgot to […]
