Electronics & embedded systems — making the part do something
One month of circuits, microcontrollers, and sensors — the course where a printed housing becomes a device that senses, decides, and acts.
What this month covers
The second course bridges mechanical and software. Students learn DC circuit fundamentals, breadboard prototyping, microcontroller programming, sensor and actuator interfacing, and basic PCB design — then build a working, battery-powered, sensor-driven device.
By the end of the month, a student can…
- CLO1Analyse a DC circuit with Ohm's and Kirchhoff's laws and predict currents, voltages, and power before building it.
- CLO2Prototype reliably on a breadboard, and use a multimeter and bench supply to bring up and debug a board.
- CLO3Program an Arduino / ESP32 microcontroller in C/C++: digital and analog I/O, timing, interrupts, and serial.
- CLO4Interface common sensors and actuators — read a sensor over I²C or analog, drive a motor or load through a proper driver.
- CLO5Draw a schematic and lay out a simple two-layer PCB in KiCad, with sane footprints and power routing.
- CLO6Solder through-hole and basic SMD joints cleanly, and inspect and rework a bad joint.
How this module advances the whole pathway
A graduate of E4’s three-month engineering pathway can do all six of the outcomes below. This one-month module carries the highlighted ones.
Where this course sits in the bigger picture
This is the course where E4's 'tangible output' rule bites hardest — nothing works until the wiring, the code, and the enclosure all agree. Students learn to debug systematically instead of guessing.
It sits in the middle of the pathway by design: it consumes the CAD skills from Month 1 (every project is enclosed in a printed housing) and it feeds the mechatronic capstone, which is essentially this course at a larger scale.
Embedded skills are the ones that convert to local income fastest — repairing and building electronics is a service Hunza needs and will pay for. That is Elevate and Empower in practice.
Each course is one month. A student’s journey with E4 is 3 months — three one-month modules that hand off to each other and finish on the mechatronic capstone.
What the student will learn to use
Arduino IDE / PlatformIO (VS Code)
ESP32 & Arduino-class boards
KiCad
Multimeter, bench supply, shared oscilloscope
Soldering station + sensor/actuator kit
One student, one month
Planning estimate in USD for Cohort 1 in Hunza, covering this one-month module for a single student on the free track.
| Instructor + teaching-assistant time (per-student share) | $34 |
| Components & consumables (MCUs, sensors, breadboards, wire, solder) | $28 |
| Bench-instrument & tool depreciation (per-student share) | $12 |
| Laptop depreciation | $10 |
| Space, power, internet | $18 |
| Assessment & device demo | $7 |
| Total — per student, 1 month | $109 |
About $109 of a roughly $350 blended three-month cost per student, across a three-module journey.
