Simple LED-Timer application paired with Blynk IOT.
This small application is a arduino implementation of a simple timer. It allows you to display a timer on a basic LED panel in combination with Blynk IOT. The timer can be simply setted over your Smartphone.
This application was created especially for my son with type-1 diabetes. Originally we used our smartphones to set up a timer and wait for injection-meal interval. Because this was very intransparent for him he asked several times when he can start to eat his sweets and get very restless. I hoped that i could make him feel more comfortable by placing a timer he can access and look at. At the end we found out that this was the case.
You will need the following hardware:
- Arduino compatible board like ESP32
- 32x8 LED-Panel
Before you transfer the application to your board please set the following configuration parameter:
#define BLYNK_TEMPLATE_ID "ENTER_TEMPLATE_ID"
#define BLYNK_DEVICE_NAME "ENTER_DEVICE_NAME"
#define BLYNK_AUTH_TOKEN "ENTER_AUTH_TOKEN"
char ssid[] = "ENTER_WLAN_SSID";
char pass[] = "ENTER_WLAN_PASSPHRASE";
Blynk.begin(auth, ssid, pass, "ENTER_BLYNK_URL", "ENTER_BLYNK_PORT_AS_INTEGER");
The timer will be controlled over a small Blynk project:
