• ESP32
• TCRT5000 Sensor
• 10K Ohm Resistor
• 100 Ohm Resistor
• 220 Ohm Resistor
• LED
• Breadboard
• Jumper Wires

Connections

ESP32

ESP32 Pin	Connection
3v3	3v3 Bus
GND	GND Bus
GPIO 2	TCRT5000 Emitter
GPIO 4	LED Anode

LED

LED Pin	Connection
Anode	ESP32 GPIO pin 4
Cathode	220 Ohm Resistor -> GND bus

TCRT5000 Sensor

TCRT 5000 Pin	Connection
Collector	3v3 Bus
Emitter	ESP32 GPIO 2 (pulled down to GND bus via 10K Ohm Resistor)
Anode	3v3 Bus
Cathode	100 Ohm Resistor -> GND bus

Build and run

Connect the ESP32 to the host then run the following command to build, run, and monitor

cargo run --release
