Week 1: We begin with an introduction with a 6-block model to visualise any electronic instrument. Each of the blocks are covered later in the course. We start with review of electronic components from wires and cables to diodes, transistors, switches, relays, optocouplers etc.
Week 2: In this week, we cover and review useful circuits and ICs. We have curated a list of commonly used circuits which we call ‘Nifty Fifty’. We also cover popular ICs such as the 555 and LM358 and RTC.
Week 3: Test and measurement instruments are key to any electronic system development. We cover DMM, DSO, LCR bridge and Logic Analyser. We also illustrate the importance of a 10:1 probe and how not to misuse a DSO by avoiding the ‘Auto Scale’ button.
Week 4: Microcontrollers are the most common ‘signal processing’ circuit blocks. We look at popular microcontroller platforms such as an Arduino, Raspberry Pi and ESP32 and how to program them. We discuss choosing an appropriate platform based on Nyquist rate.
Week 5: We cover input devices for human interaction such as switches, keypads and capacitive touch and output devices such as LEDs, displays, motors, relays etc.
Week 6: In this week, we discuss various types of sensors and analog signal conditioning circuits required to connect them to microcontrollers.
Week 7: In this section, we look at various inter and intra system communication protocols such as SPI, I2C, UART, WiFi etc. and various cloud programming options that enable to implement Internet of Things features in electronic systems.
Week 8: To be able to integrate all the elements of an electronic system, we need to learn how to use CAD software to create schematic diagrams and how to convert these diagrams into PCB layouts that can be fabricated either in the lab or in a PCB fabrication facility and then how to use various soldering techniques to build an entire system.
Week 9: Power supply is an extremely important but neglected topic. In this section, we look at various energy sources and storage options and power supply regulator circuits.
Week 10: We need to provide a suitable enclosure for our electronic instrument or system. We explore various options - from readymade enclosures to building custom enclosures using 3D printing and CNC machining. We look at basic mechanical fabrication processes in this section.
Week 11: In this section we look at steps to follow for integrating all the sub-sections to implement any given project successfully
Week 12: We finish the course with 10 sample projects, including a few IoT projects. We go through each project in detail to understand the entire journey from user requirements to finished product, including suitable documentation.
