Objetivo: leer coordenadas X/Y en un panel resistivo casero con Arduino Nano. Componentes: Arduino Nano, 16 MHz, 5 V (1x) MCP23017, expansor I/O I²C de 16 pines (1x) ADS1115, ADC I²C 16 bits (1x) Panel táctil casero, 2 láminas aluminio (1x) Resistencias serie 4.7 kΩ – 10 kΩ (4x) Fuente 5 V (USB/external) Funcionamiento: MCP23017 controla X+/X-/Y+/Y- → aplica 5 V y GND al eje activo. Ejemplo: para leer X → MCP energiza X+/X-, deja Y flotante. ADS1115 mide voltaje en el eje sin energía (ej: Y+/Y-) en modo diferencial. Arduino Nano recibe lecturas por I²C, procesa coordenadas X/Y. Coordenadas enviadas por USB serial al PC. Conexiones: Arduino Nano ↔ I²C bus ↔ MCP23017 y ADS1115 (SDA, SCL en común). MCP23017 pines → X+/X-/Y+/Y- (con resistencias serie). ADS1115 entradas analógicas → eje libre (Y+/Y- o X+/X- según ciclo). Alimentación común: 5 V + GND.

A simple walkie-talkie circuit running off an Arduino Nano. Utilizes a BJT to amplify the microphone voltage and transmits the radio signal through a nRF24L01 series Transceiver.

Universal shield for Nucleo-32 series STM32 boards and Arduino Nano with NRF24L01 on board #template #project #arduino #shield #nucleo

This is a basic design for a PCB for a 3d scanner consisting of a turntable and a z axis. it is powered by an arduino nano, 2 motor drivers.

Arduino Template based on ATMEGA328P-MU. This MCU is used in Arduino UNO Rev. 3, Arduino Nano V3.0, and some other. This template is a good starting point for your Arduino based project.

Welcome to your new project. Imagine what you can build here.

Arduino Nano RP2040 Connect with Headers - ARM® Cortex®-M0+ MCU 32-Bit Embedded Evaluation Board #template #part

Template for Arduino Nano Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Nano itself along with the board outline on the silkscreen. #Arduino #Nano #Shield #template #project #project-template
