What thismonthcovers.
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.
1 month (~20 sessions) — typically a student's second module
DURATION
Evening bench labs + weekend build sessions, ~15 students per section
FORMAT
CAD course, or equivalent comfort with technical tools; school-level maths
PREREQUISITES
A battery-powered device that reads a sensor and drives an output, in a printed enclosure
DELIVERABLE
Bench-skills check, a working breadboard demo, a KiCad schematic, and a final boxed device
ASSESSMENT
Component kit, shared bench instruments, soldering-station time, laptop
PROVIDED
By month'send, astudent 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.
Advancingthe wholepathway.
A graduate of E47’s three-month engineering pathway can do all six of the outcomes below. This one-month module carries the highlighted ones.
Where thiscoursesits.
This is the course where E47'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 E47 is 3 months — three one-month modules that hand off to each other and finish on the mechatronic capstone.
Tools thestudentwill use.
Arduino IDE / PlatformIO (VS Code)
ESP32 & Arduino-class boards
KiCad
Multimeter, bench supply, shared oscilloscope
Soldering station + sensor/actuator kit

Planning estimate in Pakistani rupees for Cohort 1 in Hunza, covering this one-month module for a single student on the free track. Priced at local rates: instructors hired in Gilgit-Baltistan, parts and filament bought in Pakistan, and free education licences wherever they exist. US dollar figures are for reference, at PKR 280 to US$1.
| Instructor + teaching-assistant time (per-student share) | PKR 6,500 | US$23 |
| Components & consumables (MCUs, sensors, breadboards, wire, solder) | PKR 1,500 | US$5 |
| Bench-instrument & tool depreciation (per-student share) | PKR 1,000 | US$4 |
| Laptop depreciation | PKR 1,000 | US$4 |
| Space, power, internet | PKR 1,500 | US$5 |
| Assessment & device demo | PKR 1,000 | US$4 |
| Total — per student, 1 month | PKR 12,500 | US$45 |
About PKR 12,500 of a roughly PKR 43,000 blended three-month cost per student, across a three-module journey.
