Production-Ready Automotive Crash Detection Controller PCB (90x60mm) – 2-Layer with Arduino Nano, SIM7600E-H, IMU & RF

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.

This circuit is an ultrasonic distance meter based on an ATTiny2313 microcontroller. It uses an HC-SR04 ultrasonic sensor to measure distance and displays the results on an OLED display. The power supply is constructed using a Boost converter (TPS613222A) and a 2-cell AA battery. Additionally, it also includes ISP for programming, RESET and START switches, and LED indicators. #project #Template #projectTemplate #ultrasonic #OLED #arduino #attiny2313 #TPS613222A #ISP #referenceDesign #simple-embedded #microchip #template #reference-design
