Electronics education requires didactic tools that integrate emerging technologies and promote hands-on experimentation in educational environments. In this context, the aim of this study was to design and implement a function generator controlled through Internet of Things (IoT) technologies, incorporating principles of ubiquitous computing to develop an accessible, flexible, and automated system. To this end, a distributed architecture was developed, consisting of a cloud-deployed web application, a database with real-time communication via WebSocket, an IoT module based on ESP8266, and a signal generator module implemented on an RP2040 microcontroller using an R-2R DAC for signal generation. The results show that the system enables the generation of sine, square, and sawtooth waveforms within a frequency range of 10 Hz to 100 kHz, with frequency errors below 0.12 % and an average control latency of 320 ms. Additionally, the prototype supports remote interaction and real-time monitoring of the devices. It is concluded that the integration of IoT into the function generator enhances electronics learning by improving accessibility, system control, and practical skills.
