Template for Arduino Nano RP2040 Connect Board. #template #project-template #arduino #rp2040

This is a 2 stage IR sensor circuit intended to be used as a ballistic speedometer/chronograph for my Coilgun. I based it off a common design for IR proximity sensors. There are 2 output pins to a microcontroller, and +/-pins for 2 IR receivers, 2 IR emitters, and 2 green LEDs to show when the stage is active. When the beam is broken the voltage on the microcontroller output pins will change, allowing me to code proper coil stage firing timing. The potentiometers are for tuning the sensitivity.

BPP104 PHOTODIODO, ALTAVOZ ULTRASONIDO Y LED IR

Cow health-monitoring wearable PCB for a cow-mounted device. Rear strap electronics target 20-25 g and front sensing assembly target about 15 g. Uses an ESP32-based sensor controller, 200 mAh LiPo battery, battery charging circuitry, and interfaces for ammonia, methane, IR temperature, and saliva sensing. Design must tolerate moisture, mucus, debris, vibration, fur contact, and tongue/lick exposure while remaining compact and lightweight for wearable use.
