A simulated blinking LED circuit using an astable multivibrator a.k.a "flip-flop" as a square wave generator. It also includes PCB layout of the project.

Overview: BME280 Sensor data -> uSD card Click on the bubble comments to see copilot design this project! Very impressed copilot routed all the SPI buses accurately for me. TODO: Just realized that there is no footprint for the SD Card holder, gotta add that Also, there needs to be a way to program the ATTINY841, Probably over UART?

Xiao could be a good way to mod your house or machines, with a simple relay controller to rule the wires.

Design Project, This design contains a +/- 5v square wave, an ohm meter, a voltmeter, a dc reference and a rail splitter.

The best way to have a friend is to build one. Jellybean is a robot friend whose gonna be right with you. Jellybean has been designed with a number of sensors to be able to interact with the environment and with the owner.

An ATtiny13 is more than sufficient to control almost any number of NeoPixels via an IR remote. The NeoController was originally developed as a tester for 800kHz NeoPixel strips. Since there was still so much flash left in the ATtiny13, an IR receiver was integrated so that some parameters can be controlled with an IR remote control. In this way, it is also suitable as a simple and cheap remote-controlled control unit for NeoPixels. Due to its small size (21.6mm x 11.4mm), it can be soldered directly to the LED strip without any problems. The power supply via a USB-C connection enables currents of up to 3A. There is still more than a third of the flash memory left for additional ideas.

This is the multipurpose PCB that works with Arduino Nano, a way that you can run 2 Stepper motors, 2 DC motors, 2 Servo motors at the same time and this is not it you can even connect BT module, rotary encoder, I2C device, potentiometer at same time. This PCB is very much helpful in building any project and no need to worry about messy wire connections.
