Circuit Central Smart Traffic Management Kit (ESP32)

Circuit Central Smart Traffic Management Kit (ESP32)

Build a four-way junction with density-based signal timing. IR sensors count vehicles on each road, the ESP32 adjusts green time automatically, and countdown displays show drivers how long is left. Wi-Fi lets you monitor the junction from a phone dashboard.

The kit is built around the ESP32 DevKit V1 and every part is chosen to work together, so students can start building on day one. All projects are programmed using the Arduino IDE (MicroPython also supported on the ESP32).

What's Included in the Kit

• 1 x ESP32 DevKit V1 (38-pin, dual-core, Wi-Fi + Bluetooth, 3.3V logic)
• 1 x USB cable (Micro-B) (For programming and power)
• 1 x MB-102 breadboard (830-point)
• 1 x Jumper wires Male to Male (40 pcs)
• 1 x Jumper wires Male to Female (40 pcs)
• 1 x Jumper wires Female to Female (40 pcs)
• 1 x Resistor pack (220Ω, 1kΩ, 2.2kΩ, 10kΩ (10 each); includes divider values for 5V sensor outputs)
• 1 x Project storage box (Reusable)
• 4 x Traffic light LED module (Red / Yellow / Green, 3.3V-5V compatible)
• 4 x IR obstacle sensor module (Vehicle detection per lane)
• 2 x TM1637 4-digit 7-segment display (Signal countdown)
• 2 x Push buttons (Pedestrian crossing request)
• 1 x Piezo buzzer (Pedestrian audio cue)
• 1 x 0.96" OLED display (I2C, junction status)
• 1 x LDR light sensor (Night-mode flashing amber)

Projects You Can Build

• Fixed-time four-way traffic signal
• Density-based green-time allocation
• Pedestrian crossing request with audio cue
• Night-mode flashing amber using an LDR
• Wi-Fi junction dashboard on a phone

What You Will Learn

• Timing and state machines for signal sequencing
• Sensor-driven adaptive control
• Multiplexing many outputs on the ESP32
• Wi-Fi monitoring of embedded systems

Who This Kit Is For

• First-year engineering students completing their course mini-project
• Engineering students across India building smart traffic management and intelligent signaling systems projects
• College labs running project-based courses and mini-projects
• Educators demonstrating practical embedded systems
• Makers and hobbyists moving beyond starter kits

Frequently Asked Questions

Is this kit suitable for first-year engineering students?
Yes. Start with the first two projects to learn the basics; the later projects are ideal for a team mini-project submission.

Why ESP32 instead of Arduino Uno?
Four traffic modules, four sensors and two displays need many pins, and the ESP32 adds Wi-Fi so the junction can be monitored remotely.

Can I build a two-way junction instead?
Yes. Use two of the four signal modules and two IR sensors; the code scales down directly.

Do I need to solder anything?
No. All modules connect with the included jumper wires and breadboard.

Which software do I use?
All projects are programmed with the Arduino IDE (MicroPython also supported on the ESP32).
