Project Title Design a Logic Gate Based Non-Programmable Sensor-Actuator PCB — Prototype Development Project Overview I need a custom electronics board designed and prototyped around a combination of Logic Gates, built for a non-programmable, hardware-only sensor-to-actuator decision system (no microcontroller/firmware involved). The board should be robust, classroom/hobbyist-safe, and ready for small-batch prototyping. Concept The core idea is a hardware logic control board where inputs (sensors which uses only digital signal like IR sensor, PIR sensor, LDR sensor etc.) and outputs (actuators/dc motors, LED and buzzer) are combined using any gate logic — with no coding or programming required. Detailed Requirements 1. Power Requirements Power input via a 9V battery. Onboard conversion to a regulated 5V supply using an LM7805 (or equivalent regulator IC). The regulated 5V output must be fed to the sensor input ports. 2. Indicator LEDs Power indication LED (Red) — shows the board is powered on. Status LEDs (Green) — one for each of the 4 output ports, indicating active output state. 4 additional LEDs to indicate inversion status — one LED per output port, showing when that port's invert switch has flipped the output signal (i.e., a dedicated "Inverted" indicator distinct from the standard Green status LED). 3. Connectors — Right-Angle JST 1x 2-pin JST connector — for battery input. 4x 3-pin JST connectors — for Inputs. 4x 3-pin JST connectors — for Outputs. 4. Output Configuration All outputs must be paired with switches to allow interconnection or separate/independent connection between ports. Input-to-output routing must support 4 connection types ( this is a must) : 1 Input → 1 Output 1 Input → Multiple Outputs Multiple Inputs → 1 Output Multiple Inputs → Multiple Outputs 5. Invert Switches 4 invert switches — one per output port — that flip/reverse the logic signal of that specific output. Each of these 4 output ports must be paired with its own dedicated inversion-indicator LED (see Section 2) that lights up when the invert switch for that port is active. Deliverables Complete schematic design (KiCad / Eagle / Altium — specify your preferred tool) PCB layout (Gerber files) Bill of Materials (BOM) Fully assembled and tested working prototype (1 unit) Basic test/validation report confirming all logic combinations (AND/OR, invert, all 4 input-output connection types) function correctly Skills Required PCB Design & Layout Analog/Digital Electronics (Logic Gates, Voltage Regulation) Embedded Hardware Prototyping Experience with JST connector-based modular hardware (preferred) Notes for Freelancers This is a non-programmable board — no microcontroller, firmware, or software logic is required. All decision logic must be implemented in hardware (discrete logic gates / ICs). Please share similar past projects (logic-gate based boards, sensor/actuator interface boards, or educational STEM hardware) if available. Open to discussing timeline and prototype iteration count before final quote. Payment after successful deliverable no matter you take 3-4 attempts in prototyping.

Hi, I can design your non-programmable logic-gate based sensor-actuator PCB with 4 digital inputs, 4 outputs, invert switches, indicator LEDs, JST connectors, 5V regulation, and hardware-only decision logic. The best solution is to first finalize the exact input/output routing matrix, gate logic requirement, actuator load type, JST pinout, switch arrangement, and enclosure/prototype expectations. Then I’ll create the schematic, design the PCB layout, prepare Gerbers/BOM, and validate the logic paths for 1 input to 1 output, 1 input to multiple outputs, multiple inputs to 1 output, and multiple inputs to multiple outputs. I’m comfortable with digital logic gates, sensor interface circuits, LM7805 power regulation, JST connector layouts, hardware-only control boards, inverter logic, LEDs/status indicators, actuator output stages, KiCad/Altium PCB design, prototyping, and test documentation. Deliverables will include: * Complete schematic * PCB layout and Gerbers * 9V to 5V power section * 4 input JST ports * 4 output JST ports * Output interconnection switches * 4 invert switches * Power/status/invert LEDs * BOM with part numbers * Prototype testing guidance * Logic validation report I’ll focus on a simple, robust, classroom-safe hardware design with no firmware or microcontroller, ensuring the board is easy to test, assemble, and use for sensor-to-actuator logic demonstrations.

Hi, We reviewed your requirements and this is an interesting hardware-only design project. We have experience in digital logic design, sensor interfaces, PCB development, and production-ready embedded hardware. We understand that this board must operate entirely with logic gate ICs, without any microcontroller or firmware. We can design a reliable and modular solution supporting all four required input-output routing modes, dedicated inversion control for each output, status indication, regulated 5V power, JST-based interfaces, and a clean PCB optimized for prototyping and future manufacturing. The design will be fully verified before prototype assembly, with complete documentation and manufacturing-ready files. Please visit our profile and portfolio to review our previous PCB and embedded hardware projects. Timeline: 7 Days Budget: ₹7,000 (We can discuss the budget further based on the final prototype scope.) A few questions: 1. Do you have a preferred logic IC family (74HC or CD4000)? 2. What is the expected current rating for each output? 3. Will prototype assembly be handled by you, or would you like us to support the complete PCBA process? We are available to start immediately and will provide regular progress updates. Regards, M&C Eng
