ESP32 – blinky with delay function

This blinky project shows how to interface LED to the ESP32 and write a simple program to make the LED blink. The full code is on Github, click here. Parts List ESP-WROOM-32 module USB<->TTL converter (3.3.V) Efficient power supply (3.3V) R1 – resistor 560Ω, see LED Resistor Calculator LED1 – basic LED Circuit Diagram Firmware … Read more

ESP32 – flashing the chip

Once the ESP32 Toolchain is built, we’re ready to compile and flash the example program. This short tutorial shows how to compile and burn the code into ESP32. Compilation Before compilation part we’re able to change menu options, i.e. we can configure the serial port to be used for uploading, etc. For the test, let’s … Read more

ATtiny13 – blinky with Watchdog Timer

Yet another ATtiny13  blinky project. In our circuit a LED is connected to PB0 and it is made to blink for roughly every second by using Watchdog Timer. The code is on Github, click here. Parts Required ATtiny13  – i.e. MBAVR-1 development board Resistor – 220Ω, see LED Resistor Calculator LED Circuit Diagram Firmware This … Read more

ATtiny13 – blinky with timer OVF (Overflow)

Yet another blinky project that is based on internal timer. In our circuit a LED is connected to PB0 and it is made to blink for roughly every second by using timer OVF (overflow). The code is on Github, click here. Parts Required ATtiny13  – i.e. MBAVR-1 development board Resistor – 220Ω, see LED Resistor … Read more
