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.

TinyCandle is a simple tealight candle simulation based on the ATtiny13A.

This board measure battery voltage and shows a current battery level. Based on ATTINY13 MCU and compatible with Arduino IDE. J1 is 6-Pin AVR ISP Connector

Battery-powered minimal ST-4 dither timer for iOptron HEM27EC: two AAA cells, ATtiny1616 controller, opto-isolated RA+/RA-/DEC+/DEC- contact closures, physical interval/intensity selectors, DITHER NOW button, and low-power status LED. The previous ESP32-S3 USB-host design is preserved only as a conditional V2 archive.
